Detailed Description

wxGrid and its related classes are used for displaying and editing tabular data.

They provide a rich set of features for display, editing, and interacting with a variety of data sources. For simple applications, and to help you get started, wxGrid is the only class you need to refer to directly. It will set up default instances of the other classes and manage them for you. For more complex applications you can derive your own classes for custom grid views, grid data tables, cell editors and renderers. The wxGrid Overview has examples of simple and more complex applications, explains the relationship between the various grid classes and has a summary of the keyboard shortcuts and mouse functions provided by wxGrid.

A wxGridTableBase class holds the actual data to be displayed by a wxGrid class. One or more wxGrid classes may act as a view for one table class. The default table class is called wxGridStringTable and holds an array of strings. An instance of such a class is created by CreateGrid().

wxGridCellRenderer is the abstract base class for rendering contents in a cell. The following renderers are predefined:

The look of a cell can be further defined using wxGridCellAttr. An object of this type may be returned by wxGridTableBase::GetAttr().

wxGridCellEditor is the abstract base class for editing the value of a cell. The following editors are predefined:

Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and wxGridEditorCreatedEvent for the documentation of all event types you can use with wxGrid.

User-Resizing and Dragging

Functions controlling various interactive mouse operations.

By default, columns and rows can be resized by dragging the edges of their labels (this can be disabled using DisableDragColSize() and DisableDragRowSize() methods). And if grid line dragging is enabled with EnableDragGridSize() they can also be resized by dragging the right or bottom edge of the grid cells.

Columns and rows can also be moved to interactively change their order but this needs to be explicitly enabled with EnableDragColMove() and EnableDragColMove().

Sorting support.

wxGrid doesn't provide any support for sorting the data but it does generate events allowing the user code to sort it and supports displaying the sort indicator in the column used for sorting.

To use wxGrid sorting support you need to handle wxEVT_GRID_COL_SORT event (and not veto it) and resort the data displayed in the grid. The grid will automatically update the sorting indicator on the column which was clicked.

You can also call the functions in this section directly to update the sorting indicator. Once again, they don't do anything with the grid data, it remains your responsibility to actually sort it appropriately.

int GetSortingColumn () const
 Return the column in which the sorting indicator is currently displayed.

void UnsetSortingColumn ()
 Remove any currently shown sorting indicator.
 
Accessors for component windows.

Return the various child windows of wxGrid.

wxGrid is an empty parent window for at least 4 children representing the column labels window (top), the row labels window (left), the corner window (top left) and the main grid window. It may be necessary to use these individual windows and not the wxGrid window itself if you need to handle events for them (using wxEvtHandler::Bind()) or do something else requiring the use of the correct window pointer. Notice that you should not, however, change these windows (e.g. reposition them or draw over them) because they are managed by wxGrid itself.

When parts of the grid are frozen using FreezeTo() function, the main grid window contains only the unfrozen part and additional windows are used for the parts containing frozen rows and/or columns and the corner window if both some rows and some columns are frozen.

Constructor & Destructor Documentation

◆ wxGrid() [1/2]

wxGrid::wxGrid ( )

Default constructor.

You must call Create() to really create the grid window and also call CreateGrid() or SetTable() or AssignTable() to initialize its contents.

◆ wxGrid() [2/2]

wxGrid::wxGrid ( wxWindow * parent,
wxWindowID id,
const wxPoint & pos = wxDefaultPosition,
const wxSize & size = wxDefaultSize,
long style = wxWANTS_CHARS,
const wxString & name = wxGridNameStr )

Constructor creating the grid window.

You must call either CreateGrid() or SetTable() or AssignTable() to initialize the grid contents before using it.

◆ ~wxGrid()

virtual wxGrid::~wxGrid ( )
virtual

Destructor.

This will also destroy the associated grid table unless you passed a table object to the grid and specified that the grid should not take ownership of the table (see SetTable()).

Member Function Documentation

◆ AppendCols()

bool wxGrid::AppendCols ( int numCols = 1,
bool updateLabels = true )

Appends one or more new columns to the right of the grid.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendCols(). See InsertCols() for further information.

Returns
true on success or false if appending columns failed.

◆ AppendRows()

bool wxGrid::AppendRows ( int numRows = 1,
bool updateLabels = true )

Appends one or more new rows to the bottom of the grid.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendRows(). See InsertRows() for further information.

Returns
true on success or false if appending rows failed.

◆ AreHorzGridLinesClipped()

bool wxGrid::AreHorzGridLinesClipped ( ) const

Return true if the horizontal grid lines stop at the last column boundary or false if they continue to the end of the window.

The default is to clip grid lines.

See also
ClipHorzGridLines(), AreVertGridLinesClipped()

◆ AreVertGridLinesClipped()

bool wxGrid::AreVertGridLinesClipped ( ) const

Return true if the vertical grid lines stop at the last row boundary or false if they continue to the end of the window.

The default is to clip grid lines.

See also
ClipVertGridLines(), AreHorzGridLinesClipped()

◆ AssignTable()

void wxGrid::AssignTable ( wxGridTableBase * table,
wxGridSelectionModes selmode = wxGridSelectCells )

Assigns a pointer to a custom grid table to be used by the grid.

This function is identical to SetTable() with takeOwnership parameter set to true, i.e. it simply always takes the ownership of the passed in pointer. This makes it simpler to use than SetTable() in the common case when the table should be owned by the grid object.

Note that this function should be called at most once and can't be used to change the table used by the grid later on or reset it: if such extra flexibility is needed, use SetTable() directly.

Since
3.1.4
Parameters
tableThe heap-allocated pointer to the table.
selmodeSelection mode to use.

◆ AutoSize()

void wxGrid::AutoSize ( )

Automatically sets the height and width of all rows and columns to fit their contents.

◆ AutoSizeColLabelSize()

void wxGrid::AutoSizeColLabelSize ( int col)

Automatically adjusts width of the column to fit its label.

◆ AutoSizeColumn()

void wxGrid::AutoSizeColumn ( int col,
bool setAsMin = true )

Automatically sizes the column to fit its contents.

If setAsMin is true the calculated width will also be set as the minimal width for the column.

◆ AutoSizeColumns()

void wxGrid::AutoSizeColumns ( bool setAsMin = true)

Automatically sizes all columns to fit their contents.

If setAsMin is true the calculated widths will also be set as the minimal widths for the columns.

◆ AutoSizeRow()

void wxGrid::AutoSizeRow ( int row,
bool setAsMin = true )

Automatically sizes the row to fit its contents.

If setAsMin is true the calculated height will also be set as the minimal height for the row.

◆ AutoSizeRowLabelSize()

void wxGrid::AutoSizeRowLabelSize ( int col)

Automatically adjusts height of the row to fit its label.

◆ AutoSizeRows()

void wxGrid::AutoSizeRows ( bool setAsMin = true)

Automatically sizes all rows to fit their contents.

If setAsMin is true the calculated heights will also be set as the minimal heights for the rows.

◆ BeginBatch()

void wxGrid::BeginBatch ( )

Increments the grid's batch count.

When the count is greater than zero repainting of the grid is suppressed. Each call to BeginBatch must be matched by a later call to EndBatch(). Code that does a lot of grid modification can be enclosed between BeginBatch() and EndBatch() calls to avoid screen flicker. The final EndBatch() call will cause the grid to be repainted.

Notice that you should use wxGridUpdateLocker which ensures that there is always a matching EndBatch() call for this BeginBatch() if possible instead of calling this method directly.

◆ BlockToDeviceRect()

wxRect wxGrid::BlockToDeviceRect ( const wxGridCellCoords & topLeft,
const wxGridCellCoords & bottomRight,
const wxGridWindow * gridWindow = NULL ) const

Convert grid cell coordinates to grid window pixel coordinates.

◆ Create()

bool wxGrid::Create ( wxWindow * parent,
wxWindowID id,
const wxPoint & pos = wxDefaultPosition,
const wxSize & size = wxDefaultSize,
long style = wxWANTS_CHARS,
const wxString & name = wxGridNameStr )

Creates the grid window for an object initialized using the default constructor.

You must call either CreateGrid() or SetTable() or AssignTable() to initialize the grid contents before using it.

◆ CreateGrid()

bool wxGrid::CreateGrid ( int numRows,
int numCols,
wxGridSelectionModes selmode = wxGridSelectCells )

Creates a grid with the specified initial number of rows and columns.

Call this directly after the grid constructor. When you use this function wxGrid will create and manage a simple table of string values for you. All of the grid data will be stored in memory.

For applications with more complex data types or relationships, or for dealing with very large datasets, you should derive your own grid table class and pass a table object to the grid with SetTable() or AssignTable().

◆ DeleteCols()

bool wxGrid::DeleteCols ( int pos = 0,
int numCols = 1,
bool updateLabels = true )

Deletes one or more columns from a grid starting at the specified position.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::DeleteCols(). See InsertCols() for further information.

Returns
true on success or false if deleting columns failed.

◆ DeleteRows()

bool wxGrid::DeleteRows ( int pos = 0,
int numRows = 1,
bool updateLabels = true )

Deletes one or more rows from a grid starting at the specified position.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::DeleteRows(). See InsertRows() for further information.

Returns
true on success or false if deleting rows failed.

◆ DeselectCell()

void wxGrid::DeselectCell ( int row,
int col )

Deselects a cell.

Deselects a row of cells.

◆ DevicePosToGridWindow() [1/2]

wxGridWindow * wxGrid::DevicePosToGridWindow ( int x,
int y ) const

wxGridWindow * wxGrid::DevicePosToGridWindow ( wxPoint pos) const

Returns the grid window that includes the input coordinates.

Since
3.1.3

◆ DisableCellEditControl()

void wxGrid::DisableCellEditControl ( )

Disables in-place editing of grid cells.

Equivalent to calling EnableCellEditControl(false).

◆ DisableColResize()

void wxGrid::DisableColResize ( int col)

Disable interactive resizing of the specified column.

This method allows one to disable resizing of an individual column in a grid where the columns are otherwise resizable (which is the case by default).

Notice that currently there is no way to make some columns resizable in a grid where columns can't be resized by default as there doesn't seem to be any need for this in practice. There is also no way to make the column marked as fixed using this method resizable again because it is supposed that fixed columns are used for static parts of the grid and so should remain fixed during the entire grid lifetime.

Also notice that disabling interactive column resizing will not prevent the program from changing the column size.

See also
EnableDragColSize()

◆ DisableDragColMove()

void wxGrid::DisableDragColMove ( )

Disables column moving by dragging with the mouse.

Equivalent to passing false to EnableDragColMove().

◆ DisableDragColSize()

int horizontalAlignment = wxALIGN_LEFT,
int verticalAlignment = wxALIGN_TOP,
int textOrientation = wxHORIZONTAL ) const

◆ EnableCellEditControl()

void wxGrid::EnableCellEditControl ( bool enable = true)

Enables or disables in-place editing of grid cell data.

Enabling in-place editing generates wxEVT_GRID_EDITOR_SHOWN and, if it isn't vetoed by the application, shows the in-place editor which allows the user to change the cell value.

Disabling in-place editing does nothing if the in-place editor isn't currently shown, otherwise the wxEVT_GRID_EDITOR_HIDDEN event is generated but, unlike the "shown" event, it can't be vetoed and the in-place editor is dismissed unconditionally.

Note that it is an error to call this function if the current cell is read-only, use CanEnableCellControl() to check for this precondition.

◆ EnableDragCell()

void wxGrid::EnableDragCell ( bool enable = true)

Enables or disables cell dragging with the mouse.

◆ EnableDragColMove()

bool wxGrid::EnableDragColMove ( bool enable = true)

Enables or disables column moving by dragging with the mouse.

Note that reordering columns by dragging them is currently not supported when the grid has any frozen columns (see FreezeTo()) and if this method is called with enable equal to true in this situation, it returns false without doing anything. Otherwise it returns true to indicate that it was successful.

◆ EnableDragColSize()

void wxGrid::EnableDragColSize ( bool enable = true)

Enables or disables column sizing by dragging with the mouse.

See also
DisableColResize()

◆ EnableDragGridSize()

◆ EnableDragRowMove()

bool wxGrid::EnableDragRowMove ( bool enable = true)

Enables or disables row moving by dragging with the mouse.

Note that reordering rows by dragging them is currently not supported when the grid has any frozen columns (see FreezeTo()) and if this method is called with enable equal to true in this situation, it returns false without doing anything. Otherwise it returns true to indicate that it was successful.

Since
3.1.7

◆ EnableDragRowSize()

void wxGrid::EnableDragRowSize ( bool enable = true)

Enables or disables row sizing by dragging with the mouse.

DisableRowResize()

◆ EnableEditing()

void wxGrid::EnableEditing ( bool edit)

Makes the grid globally editable or read-only.

If the edit argument is false this function sets the whole grid as read-only. If the argument is true the grid is set to the default state where cells may be editable. In the default state you can set single grid cells and whole rows and columns to be editable or read-only via wxGridCellAttr::SetReadOnly(). For single cells you can also use the shortcut function SetReadOnly().

For more information about controlling grid cell attributes see the wxGridCellAttr class and the wxGrid Overview.

◆ EnableGridLines()

void wxGrid::EnableGridLines ( bool enable = true)

Turns the drawing of grid lines on or off.

◆ EnableHidingColumns()

bool wxGrid::EnableHidingColumns ( bool enable = true)

Enables or disables column hiding from the header popup menu.

Note that currently the popup menu can only be shown when using wxHeaderCtrl, i.e. if UseNativeColHeader() had been called.

If the native header is not used, this method always simply returns false without doing anything, as hiding columns is not supported anyhow. If enable value is the same as CanHideColumns(), it also returns false to indicate that nothing was done. Otherwise, it returns true to indicate that the value of this option was successfully changed.

The main use case for this method is to disallow hiding the columns interactively when using the native header.

Since
3.1.3

DisableHidingColumns()

◆ EndBatch()

void wxGrid::EndBatch ( )

Decrements the grid's batch count.

When the count is greater than zero repainting of the grid is suppressed. Each previous call to BeginBatch() must be matched by a later call to EndBatch(). Code that does a lot of grid modification can be enclosed between BeginBatch() and EndBatch() calls to avoid screen flicker. The final EndBatch() will cause the grid to be repainted.

wxGridUpdateLocker

◆ Fit()

virtual void wxGrid::Fit ( )
virtual

Overridden wxWindow method.

Reimplemented from wxWindow.

◆ ForceRefresh()

void wxGrid::ForceRefresh ( )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ FreezeTo() [2/2]

bool wxGrid::FreezeTo ( unsigned row,
unsigned col )

Sets or resets the frozen columns and rows.

Parameters
rowThe number of rows to freeze, 0 means to unfreeze all rows.
colThe number of columns to freeze, 0 means to unfreeze all columns.
Returns
true on success or false if it failed.

Note that this method doesn't do anything, and returns false, if any of the following conditions are true:

  • Either row or col are out of range
  • Size of the frozen area would be bigger than the current viewing area
  • There are any merged cells in the area to be frozen
  • Grid uses a native header control (see UseNativeColHeader())

(some of these limitations could be lifted in the future).

Since
3.1.3

◆ GetBatchCount()

int wxGrid::GetBatchCount ( ) const

Returns the number of times that BeginBatch() has been called without (yet) matching calls to EndBatch().

While the grid's batch count is greater than zero the display will not be updated.

◆ GetCellHighlightColour()

wxColour wxGrid::GetCellHighlightColour ( ) const

◆ GetCellHighlightPenWidth()

int wxGrid::GetCellHighlightPenWidth ( ) const

◆ GetCellHighlightROPenWidth()

int wxGrid::GetCellHighlightROPenWidth ( ) const

◆ GetCellOverflow()

bool wxGrid::GetCellOverflow ( int row,
int col ) const

Returns true if the cell value can overflow.

This is identical to calling GetCellFitMode() and using wxGridFitMode::IsOverflow() on the returned value.

Prefer using GetCellFitMode() directly in the new code.

◆ GetCellRenderer()

wxGridCellRenderer * wxGrid::GetCellRenderer ( int row,
int col ) const

Returns a pointer to the renderer for the grid cell at the specified location.

See wxGridCellRenderer and the wxGrid Overview for more information about cell editors and renderers.

The caller must call DecRef() on the returned pointer.

◆ GetCellSize() [1/2]

wxSize wxGrid::GetCellSize ( const wxGridCellCoords & coords) const

Get the number of rows and columns allocated for this cell.

This overload doesn't return a CellSpan value but the values returned may still be negative, see GetCellSize(int, int, int *, int *) for details.

◆ GetCellSize() [2/2]

CellSpan wxGrid::GetCellSize ( int row,
int col,
int * num_rows,
int * num_cols ) const

Get the size of the cell in number of cells covered by it.

For normal cells, the function fills both num_rows and num_cols with 1 and returns CellSpan_None. For cells which span multiple cells, i.e. for which SetCellSize() had been called, the returned values are the same ones as were passed to SetCellSize() call and the function return value is CellSpan_Main.

More unexpectedly, perhaps, the returned values may be negative for the cells which are inside a span covered by a cell occupying multiple rows or columns. They correspond to the offset of the main cell of the span from the cell passed to this functions and the function returns CellSpan_Inside value to indicate this.

As an example, consider a 3*3 grid with the cell (1, 1) (the one in the middle) having a span of 2 rows and 2 columns, i.e. the grid looks like

+----+----+----+
| | | |
+----+----+----+
| | |
+----+ |
| | |
+----+----+----+

Then the function returns 2 and 2 in num_rows and num_cols for the cell (1, 1) itself and -1 and -1 for the cell (2, 2) as well as -1 and 0 for the cell (2, 1).

Parameters
rowThe row of the cell.
colThe column of the cell.
num_rowsPointer to variable receiving the number of rows, must not be NULL.
num_colsPointer to variable receiving the number of columns, must not be NULL.
Returns
The kind of this cell span (the return value is new in wxWidgets 2.9.1, this function was void in previous wxWidgets versions).

◆ GetCellTextColour()

wxColour wxGrid::GetCellTextColour ( int row,
int col ) const

Returns the text colour for the grid cell at the specified location.

◆ GetCellValue() [1/2]

wxString wxGrid::GetCellValue ( const wxGridCellCoords & coords) const

Returns the string contained in the cell at the specified location.

For simple applications where a grid object automatically uses a default grid table of string values you use this function together with SetCellValue() to access cell values. For more complex applications where you have derived your own grid table class that contains various data types (e.g. numeric, boolean or user-defined custom types) then you only use this function for those cells that contain string values.

See wxGridTableBase::CanGetValueAs() and the wxGrid Overview for more information.

◆ GetSelectedBlocks()

wxGridBlocks wxGrid::GetSelectedBlocks ( ) const

Returns a range of grid selection blocks.

The returned range can be iterated over, e.g. with C++11 range-for loop:

for ( const auto block: grid->GetSelectedBlocks() ) {
if ( block.Intersects(myBlock) )
break;
}

Notice that the blocks returned by this method are not ordered in any particular way and may overlap. For grids using rows or columns-only selection modes, GetSelectedRowBlocks() or GetSelectedColBlocks() can be more convenient, as they return ordered and non-overlapping blocks.

Since
3.1.4

◆ GetSelectedCells()

wxGridCellCoordsArray wxGrid::GetSelectedCells ( ) const

Returns an array of individually selected cells.

Notice that this array does not contain all the selected cells in general as it doesn't include the cells selected as part of column, row or block selection. You must use this method, GetSelectedCols(), GetSelectedRows() and GetSelectionBlockTopLeft() and GetSelectionBlockBottomRight() methods to obtain the entire selection in general.

Please notice this behaviour is by design and is needed in order to support grids of arbitrary size (when an entire column is selected in a grid with a million of columns, we don't want to create an array with a million of entries in this function, instead it returns an empty array and GetSelectedCols() returns an array containing one element).

The function can be slow for the big grids, use GetSelectedBlocks() in the new code.

◆ GetSelectedColBlocks()

wxGridBlockCoordsVector wxGrid::GetSelectedColBlocks ( ) const

Returns an ordered range of non-overlapping selected columns.

This method is symmetric to GetSelectedRowBlocks(), but is useful only in wxGridSelectColumns selection mode.

See also
GetSelectedBlocks()
Since
3.1.4

◆ GetSelectedCols()

wxArrayInt wxGrid::GetSelectedCols ( ) const

Returns an array of selected columns.

Please notice that this method alone is not sufficient to find all the selected columns as it contains only the columns which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see GetSelectedCells() for more details.

The function can be slow for the big grids, use GetSelectedBlocks() in the new code.

◆ GetSelectedRowBlocks()

wxGridBlockCoordsVector wxGrid::GetSelectedRowBlocks ( ) const

Returns an ordered range of non-overlapping selected rows.

For the grids using wxGridSelectRows selection mode, returns the possibly empty vector containing the coordinates of non-overlapping selected row blocks in the natural order, i.e. from smallest to the biggest row indices.

To see the difference between this method and GetSelectedBlocks(), consider the case when the user selects rows 2..4 in the grid and then also selects (using Ctrl/Shift keys) the rows 1..3. Iterating over the result of GetSelectedBlocks() would yield two blocks directly corresponding to the users selection, while this method returns a vector with a single element corresponding to the rows 1..4.

This method returns empty vector for the other selection modes.

GetSelectedBlocks(), GetSelectedColBlocks()
Since
3.1.4

◆ GetSelectedRows()

wxArrayInt wxGrid::GetSelectedRows ( ) const

Returns an array of selected rows.

Please notice that this method alone is not sufficient to find all the selected rows as it contains only the rows which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see GetSelectedCells() for more details.

The function can be slow for the big grids, use GetSelectedBlocks() in the new code.

◆ GetSelectionBackground()

wxColour wxGrid::GetSelectionBackground ( ) const

Returns the colour used for drawing the selection background.

◆ GetSelectionBlockBottomRight()

wxGridCellCoordsArray wxGrid::GetSelectionBlockBottomRight ( ) const

Returns an array of the bottom right corners of blocks of selected cells.

Please see GetSelectedCells() for more information about the selection representation in wxGrid.

The function can be slow for the big grids, use GetSelectedBlocks() in the new code.

GetSelectionBlockBottomRight()

◆ GetSelectionForeground()

wxColour wxGrid::GetSelectionForeground ( ) const

Returns the colour used for drawing the selection foreground.

Returns wxNOT_FOUND if sorting indicator is not currently displayed at all.

See also
SetSortingColumn()

◆ GetTable()

wxGridTableBase * wxGrid::GetTable ( ) const

Returns a base pointer to the current table object.

The returned pointer is still owned by the grid.

◆ GoToCell() [1/2]

void wxGrid::GoToCell ( const wxGridCellCoords & coords)

Make the given cell current and ensure it is visible.

This method is equivalent to calling MakeCellVisible() and SetGridCursor() and so, as with the latter, a wxEVT_GRID_SELECT_CELL event is generated by it and the selected cell doesn't change if the event is vetoed.

◆ GoToCell() [2/2]

void wxGrid::GoToCell ( int row,
int col )

Make the given cell current and ensure it is visible.

This method is equivalent to calling MakeCellVisible() and SetGridCursor() and so, as with the latter, a wxEVT_GRID_SELECT_CELL event is generated by it and the selected cell doesn't change if the event is vetoed.

◆ GridLinesEnabled()

bool wxGrid::GridLinesEnabled ( ) const

Returns true if drawing of grid lines is turned on, false otherwise.

◆ HideCellEditControl()

void wxGrid::HideCellEditControl ( )

Hides the in-place cell edit control.

◆ HideCol()

void wxGrid::HideCol ( int col)

Hides the specified column.

To show the column later you need to call SetColSize() with non-0 width or ShowCol() to restore the previous column width.

If the column is already hidden, this method doesn't do anything.

Parameters
colThe column index.

◆ HideColLabels()

void wxGrid::HideColLabels ( )

Hides the column labels by calling SetColLabelSize() with a size of 0.

The labels can be shown again by calling SetColLabelSize() with a height greater than 0.

Note that when the column labels are hidden, the grid won't have any visible border on the top side, which may result in a less than ideal appearance. Because of this, you may want to create the grid window with a border style, such as wxBORDER_SIMPLE, when you don't plan to show the column labels for it.

See also
HideRowLabels()

◆ HideRow()

void wxGrid::HideRow ( int col)

Hides the specified row.

To show the row later you need to call SetRowSize() with non-0 width or ShowRow() to restore its original height.

If the row is already hidden, this method doesn't do anything.

Parameters
colThe row index.

◆ HideRowLabels()

void wxGrid::HideRowLabels ( )

Hides the row labels by calling SetRowLabelSize() with a size of 0.

The labels can be shown again by calling SetRowLabelSize() with a width greater than 0.

See HideColLabels() for a note explaining why you may want to use a border with a grid without the row labels.

◆ InsertCols()

bool wxGrid::InsertCols ( int pos = 0,
int numCols = 1,
bool updateLabels = true )

Inserts one or more new columns into a grid with the first new column at the specified position.

Notice that inserting the columns in the grid requires grid table cooperation: when this method is called, grid object begins by requesting the underlying grid table to insert new columns. If this is successful the table notifies the grid and the grid updates the display. For a default grid (one where you have called CreateGrid()) this process is automatic. If you are using a custom grid table (specified with SetTable() or AssignTable()) then you must override wxGridTableBase::InsertCols() in your derived table class.

Parameters
posThe position which the first newly inserted column will have.
numColsThe number of columns to insert.
updateLabelsCurrently not used.
Returns
true if the columns were successfully inserted, false if an error occurred (most likely the table couldn't be updated).

◆ InsertRows()

bool wxGrid::InsertRows ( int pos = 0,
int numRows = 1,
bool updateLabels = true )

Inserts one or more new rows into a grid with the first new row at the specified position.

Notice that you must implement wxGridTableBase::InsertRows() if you use a grid with a custom table, please see InsertCols() for more information.

Parameters
posThe position which the first newly inserted row will have.
numRowsThe number of rows to insert.
updateLabelsCurrently not used.
Returns
true if the rows were successfully inserted, false if an error occurred (most likely the table couldn't be updated).

◆ ProcessTableMessage()

bool wxGrid::ProcessTableMessage ( wxGridTableMessage & msg)

Receive and handle a message from the table.

◆ RefreshAttr()

void wxGrid::RefreshAttr ( int row,
int col )

Invalidates the cached attribute for the given cell.

For efficiency reasons, wxGrid may cache the recently used attributes (currently it caches only the single most recently used one, in fact) which can result in the cell appearance not being refreshed even when the attribute returned by your custom wxGridCellAttrProvider-derived class has changed. To force the grid to refresh the cell attribute, this function may be used. Notice that calling it will not result in actually redrawing the cell, you still need to call wxWindow::RefreshRect() to invalidate the area occupied by the cell in the window to do this. Also note that you don't need to call this function if you store the attributes in wxGrid itself, i.e. use its SetAttr() and similar methods, it is only useful when using a separate custom attributes provider.

Parameters
rowThe row of the cell whose attribute needs to be queried again.
colThe column of the cell whose attribute needs to be queried again.
Since
2.9.2

◆ RefreshBlock() [1/2]

void wxGrid::RefreshBlock ( const wxGridCellCoords & topLeft,
const wxGridCellCoords & bottomRight )

Redraw all the cells in the given block.

Refresh the block of cells with the given corners.

If the bottom right corner coordinates are invalid, i.e. set to -1, the top left corner coordinates are used for it, i.e. just a single cell is refreshed. If the top left corner coordinates are invalid as well, the function simply returns without doing anything. Note, however, that both coordinates need to be valid or invalid simultaneously, i.e. setting the top row to -1 but using a valid value for the left column is unsupported and would result in an assertion failure.

Since
3.1.3

◆ RefreshBlock() [2/2]

void wxGrid::RefreshBlock ( int topRow,
int leftCol,
int bottomRow,
int rightCol )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ RegisterDataType()

void wxGrid::RegisterDataType ( const wxString & typeName,
wxGridCellRenderer * renderer,
wxGridCellEditor * editor )

Register a new data type.

The data types allow to naturally associate specific renderers and editors to the cells containing values of the given type. For example, the grid automatically registers a data type with the name wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and wxGridCellTextEditor as its renderer and editor respectively – this is the data type used by all the cells of the default wxGridStringTable, so this renderer and editor are used by default for all grid cells.

However if a custom table returns wxGRID_VALUE_BOOL from its wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and wxGridCellBoolEditor are used for it because the grid also registers a boolean data type with this name.

And as this mechanism is completely generic, you may register your own data types using your own custom renderers and editors. Just remember that the table must identify a cell as being of the given type for them to be used for this cell.

Parameters
typeNameName of the new type. May be any string, but if the type name is the same as the name of an already registered type, including one of the standard ones (which are wxGRID_VALUE_STRING, wxGRID_VALUE_BOOL, wxGRID_VALUE_NUMBER, wxGRID_VALUE_FLOAT, wxGRID_VALUE_CHOICE and wxGRID_VALUE_DATE), then the new registration information replaces the previously used renderer and editor.
rendererThe renderer to use for the cells of this type. Its ownership is taken by the grid, i.e. it will call DecRef() on this pointer when it doesn't need it any longer.
editorThe editor to use for the cells of this type. Its ownership is also taken by the grid.

◆ Render()

void wxGrid::Render ( wxDC & dc,
const wxPoint & pos = wxDefaultPosition,
const wxSize & size = wxDefaultSize,
const wxGridCellCoords & topLeft = wxGridCellCoords(-1, -1),
const wxGridCellCoords & bottomRight = wxGridCellCoords(-1, -1),
int style = wxGRID_DRAW_DEFAULT )

Draws part or all of a wxGrid on a wxDC for printing or display.

Pagination can be accomplished by using sequential Render() calls with appropriate values in wxGridCellCoords topLeft and bottomRight.

Parameters
dcThe wxDC to be drawn on.
posThe position on the wxDC where rendering should begin. If not specified drawing will begin at the wxDC MaxX() and MaxY().
sizeThe size of the area on the wxDC that the rendered wxGrid should occupy. If not specified the drawing will be scaled to fit the available dc width or height. The wxGrid's aspect ratio is maintained whether or not size is specified.
topLeftThe top left cell of the block to be drawn. Defaults to ( 0, 0 ).
bottomRightThe bottom right cell of the block to be drawn. Defaults to row and column counts.
styleA combination of values from wxGridRenderStyle.

◆ SaveEditControlValue()

void wxGrid::SaveEditControlValue ( )

Sets the value of the current grid cell to the current in-place edit control value.

◆ SetColFormatCustom()

void wxGrid::SetColFormatCustom ( int col,
const wxString & typeName )

Sets the specified column to display data in a custom format.

This method provides an alternative to defining a custom grid table which would return typeName from its GetTypeName() method for the cells in this column: while it doesn't really change the type of the cells in this column, it does associate the renderer and editor used for the cells of the specified type with them.

See the wxGrid Overview for more information on working with custom data types.

◆ SetColFormatDate()

See wxGridCellEditor and the wxGrid Overview for more information about cell editors and renderers.

◆ SetDefaultRenderer()

void wxGrid::SetDefaultRenderer ( wxGridCellRenderer * renderer)

Sets the default renderer for grid cells.

The grid will take ownership of the pointer.

See wxGridCellRenderer and the wxGrid Overview for more information about cell editors and renderers.

◆ SetDefaultRowSize()

void wxGrid::SetDefaultRowSize ( int height,
bool resizeExistingRows = false )

Sets the default height for rows in the grid.

This will only affect rows subsequently added to the grid unless resizeExistingRows is true.

If height is less than GetRowMinimalAcceptableHeight(), then the minimal acceptable height is used instead of it.

◆ SetGridCursor() [1/2]

void wxGrid::SetGridCursor ( const wxGridCellCoords & coords)

Set the grid cursor to the specified cell.

The grid cursor indicates the current cell and can be moved by the user using the arrow keys or the mouse.

Calling this function generates a wxEVT_GRID_SELECT_CELL event and if the event handler vetoes this event, the cursor is not moved.

This function doesn't make the target call visible, use GoToCell() to do this.

◆ SetGridCursor() [2/2]

void wxGrid::SetGridCursor ( int row,
int col )

Set the grid cursor to the specified cell.

The grid cursor indicates the current cell and can be moved by the user using the arrow keys or the mouse.

Calling this function generates a wxEVT_GRID_SELECT_CELL event and if the event handler vetoes this event, the cursor is not moved.

This function doesn't make the target call visible, use GoToCell() to do this.

◆ SetGridFrozenBorderColour()

void wxGrid::SetGridFrozenBorderColour ( const wxColour & )

◆ SetGridFrozenBorderPenWidth()

void wxGrid::SetGridFrozenBorderPenWidth ( int width)

◆ SetGridLineColour()

void wxGrid::SetGridLineColour ( const wxColour & colour)

Sets the colour used to draw grid lines.

◆ SetLabelBackgroundColour()

void wxGrid::SetLabelBackgroundColour ( const wxColour & colour)

Sets the background colour for row and column labels.

int extraHeight )

Sets the extra margins used around the grid area.

A grid may occupy more space than needed for its data display and this function allows setting how big this extra space is

◆ SetReadOnly()

void wxGrid::SetReadOnly ( int row,
int col,
bool isReadOnly = true )

Makes the cell at the specified location read-only or editable.

See also
IsReadOnly()

◆ SetRowAttr()

void wxGrid::SetRowAttr ( int row,
wxGridCellAttr * attr )

Sets the cell attributes for all cells in the specified row.

The grid takes ownership of the attribute pointer.

See the wxGridCellAttr class for more information about controlling cell attributes.

◆ SetRowLabelAlignment()

void wxGrid::SetRowLabelAlignment ( int horiz,
int vert )

Sets the horizontal and vertical alignment of row label text.

Horizontal alignment should be one of wxALIGN_LEFT, wxALIGN_CENTRE or wxALIGN_RIGHT. Vertical alignment should be one of wxALIGN_TOP, wxALIGN_CENTRE or wxALIGN_BOTTOM.

◆ SetRowLabelSize()

void wxGrid::SetRowLabelSize ( int width)

Sets the width of the row labels.

If width equals wxGRID_AUTOSIZE then width is calculated automatically so that no label is truncated. Note that this could be slow for a large table.

◆ SetRowLabelValue()

void wxGrid::SetRowLabelValue ( int row,
const wxString & value )

Sets the value for the given row label.

If you are using a derived grid table you must override wxGridTableBase::SetRowLabelValue() for this to have any effect.

◆ SetRowMinimalAcceptableHeight()

void wxGrid::SetRowMinimalAcceptableHeight ( int height)

Sets the minimal row height used by default.

See SetColMinimalAcceptableWidth() for more information.

◆ SetRowMinimalHeight()

void wxGrid::SetRowMinimalHeight ( int row,
int height )

Sets the minimal height for the specified row.

See SetColMinimalWidth() for more information.

◆ SetRowPos()

void wxGrid::SetRowPos ( int rowID,
int newPos )

Sets the position of the specified row.

Since
3.1.7

◆ SetRowSize()

void wxGrid::SetRowSize ( int row,
int height )

Sets the height of the specified row.

See SetColSize() for more information.

◆ SetRowSizes()

Restore all rows sizes.

See also
SetColSizes()

◆ SetRowsOrder()

void wxGrid::SetRowsOrder ( const wxArrayInt & order)

This method takes an array containing the indices of the rows in their display order.

Since
3.1.7

◆ SetScrollLineX()

void wxGrid::SetScrollLineX ( int x)

Sets the number of pixels per horizontal scroll increment.

The default is 15.

See also
GetScrollLineX(), GetScrollLineY(), SetScrollLineY()

◆ SetScrollLineY()

void wxGrid::SetScrollLineY ( int y)

Sets the number of pixels per vertical scroll increment.

The default is 15.

GetScrollLineX(), GetScrollLineY(), SetScrollLineX()

◆ SetSelectionBackground()

void wxGrid::SetSelectionBackground ( const wxColour & c)

Set the colour to be used for drawing the selection background.

◆ SetSelectionForeground()

void wxGrid::SetSelectionForeground ( const wxColour & c)

Set the colour to be used for drawing the selection foreground.

◆ SetSelectionMode()

void wxGrid::SetSelectionMode ( wxGridSelectionModes selmode)

Set the selection behaviour of the grid.

The existing selection is converted to conform to the new mode if possible and discarded otherwise (e.g. any individual selected cells are deselected if the new mode allows only the selection of the entire rows or columns).

◆ SetSortingColumn()

void wxGrid::SetSortingColumn ( int col,
bool ascending = true )

Set the column to display the sorting indicator in and its direction.

Parameters
colThe column to display the sorting indicator in or wxNOT_FOUND to remove any currently displayed sorting indicator.
ascendingIf true, display the ascending sort indicator, otherwise display the descending sort indicator.
See also
GetSortingColumn(), IsSortOrderAscending()

◆ SetTabBehaviour()

void wxGrid::SetTabBehaviour ( TabBehaviour behaviour)

Set the grid's behaviour when the user presses the TAB key.

Pressing the TAB key moves the grid cursor right in the current row, if there is a cell at the right and, similarly, Shift-TAB moves the cursor to the left in the current row if it's not in the first column.

What happens if the cursor can't be moved because it it's already at the beginning or end of the row can be configured using this function, see wxGrid::TabBehaviour documentation for the detailed description.

IF none of the standard behaviours is appropriate, you can always handle wxEVT_GRID_TABBING event directly to implement a custom TAB-handling logic.

Since
2.9.5

◆ SetTable()

bool wxGrid::SetTable ( wxGridTableBase * table,
bool takeOwnership = false,
wxGridSelectionModes selmode = wxGridSelectCells )

Passes a pointer to a custom grid table to be used by the grid.

This should be called after the grid constructor and before using the grid object. If takeOwnership is set to true then the table will be deleted by the wxGrid destructor.

Use this function instead of CreateGrid() when your application involves complex or non-string data or data sets that are too large to fit wholly in memory.

When the custom table should be owned by the grid, consider using the simpler AssignTable() function instead of this one with true value of takeOwnership parameter.

◆ SetUseNativeColLabels()

void wxGrid::SetUseNativeColLabels ( bool native = true)

Call this in order to make the column labels use a native look by using wxRendererNative::DrawHeaderButton() internally.

There is no equivalent method for drawing row columns as there is not native look for that. This option is useful when using wxGrid for displaying tables and not as a spread-sheet.

See also
UseNativeColHeader()

◆ ShowCellEditControl()

void wxGrid::ShowCellEditControl ( )

Displays the active in-place cell edit control for the current cell after it was hidden.

This method should only be called after calling HideCellEditControl(), to start editing the current grid cell use EnableCellEditControl() instead.

◆ ShowCol()

void wxGrid::ShowCol ( int col)

Shows the previously hidden column by resizing it to non-0 size.

The column is shown again with the same width that it had before HideCol() call.

If the column is currently shown, this method doesn't do anything.

See also
HideCol(), SetColSize()

◆ ShowRow()

void wxGrid::ShowRow ( int col)

Shows the previously hidden row.

The row is shown again with the same height that it had before HideRow() call.

If the row is currently shown, this method doesn't do anything.

See also
HideRow(), SetRowSize()

◆ UnsetSortingColumn()

void wxGrid::UnsetSortingColumn ( )

Remove any currently shown sorting indicator.

This is equivalent to calling SetSortingColumn() with wxNOT_FOUND first argument.

◆ UseNativeColHeader()

bool wxGrid::UseNativeColHeader ( bool native = true)

Enable the use of native header window for column labels.

If this function is called with true argument, a wxHeaderCtrl is used instead to display the column labels instead of drawing them in wxGrid code itself. This has the advantage of making the grid look and feel perfectly the same as native applications (using SetUseNativeColLabels() the grid can be made to look more natively but it still doesn't feel natively, notably the column resizing and dragging still works slightly differently as it is implemented in wxWidgets itself) but results in different behaviour for column and row headers, for which there is no equivalent function, and, most importantly, is unsuitable for grids with huge numbers of columns as wxHeaderCtrl doesn't support virtual mode. Because of this, by default the grid does not use the native header control but you should call this function to enable it if you are using the grid to display tabular data and don't have thousands of columns in it.

Another difference between the default behaviour and the native header behaviour is that the latter provides the user with a context menu (which appears on right clicking the header) allowing to rearrange the grid columns if CanDragColMove() returns true. If you want to prevent this from happening for some reason, you need to define a handler for wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in particular doesn't skip the event) as this will prevent the default right click handling from working.

Also note that currently wxEVT_GRID_LABEL_RIGHT_DCLICK event is not generated for the column labels if the native columns header is used (but this limitation could possibly be lifted in the future).

Finally, please note that using the native control is currently incompatible with freezing columns in the grid (see FreezeTo()) and this function will return false, without doing anything, if it's called on a grid in which any columns are frozen.

◆ XToCol()

int wxGrid::XToCol ( int x,
bool clipToMinMax = false,
wxGridWindow * gridWindow = NULL ) const

Returns the column at the given pixel position depending on the window.

Parameters
xThe x position to evaluate.
clipToMinMaxIf true, rather than returning wxNOT_FOUND, it returns either the first or last column depending on whether x is too far to the left or right respectively.
gridWindowThe associated grid window that limits the search (note that this parameter is only available since wxWidgets 3.1.3). If gridWindow is NULL, it will consider all the cells, no matter which grid they belong to.
Returns
The column index or wxNOT_FOUND.

◆ XToEdgeOfCol()

int wxGrid::XToEdgeOfCol ( int x) const

Returns the column whose right hand edge is close to the given logical x position.

If no column edge is near to this position wxNOT_FOUND is returned.

◆ XYToCell() [1/2]

wxGridCellCoords wxGrid::XYToCell ( const wxPoint & pos,
wxGridWindow * gridWindow = NULL ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ XYToCell() [2/2]

wxGridCellCoords wxGrid::XYToCell ( int x,
int y,
wxGridWindow * gridWindow = NULL ) const

Translates logical pixel coordinates to the grid cell coordinates.

Notice that this function expects logical coordinates on input so if you use this function in a mouse event handler you need to translate the mouse position, which is expressed in device coordinates, to logical ones.

The parameter gridWindow is new since wxWidgets 3.1.3. If it is specified, i.e. non-NULL, the coordinates must be in this window coordinate system and only the cells of this window are considered, i.e. the function returns wxNOT_FOUND if the coordinates are out of bounds.

If gridWindow is NULL, coordinates are relative to the main grid window and all cells are considered.

XToCol(), YToRow()

◆ YToEdgeOfRow()

int wxGrid::YToEdgeOfRow ( int y) const

Returns the row whose bottom edge is close to the given logical y position.

If no row edge is near to this position wxNOT_FOUND is returned.

◆ YToRow()

int wxGrid::YToRow ( int y,
bool clipToMinMax = false,
wxGridWindow * gridWindow = NULL ) const

Returns the grid row that corresponds to the logical y coordinate.

The parameter gridWindow is new since wxWidgets 3.1.3. If it is specified, i.e. non-NULL, only the cells of this window are considered, i.e. the function returns wxNOT_FOUND if y is out of bounds.

If gridWindow is NULL, the function returns wxNOT_FOUND only if there is no row at all at the y position.
