Class DateTime
- All Implemented Interfaces:
Drawable
Note that although this class is a subclass of Composite,
it does not make sense to add children to it, or set a layout on it.
- Styles:
- DATE, TIME, CALENDAR, SHORT, MEDIUM, LONG, DROP_DOWN, CALENDAR_WEEKNUMBERS
- Events:
- DefaultSelection, Selection
Note: Only one of the styles DATE, TIME, or CALENDAR may be specified, and only one of the styles SHORT, MEDIUM, or LONG may be specified. The DROP_DOWN style is only valid with the DATE style.
IMPORTANT: This class is not intended to be subclassed.

DateTime
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.The style value is either one of the style constants defined in class
SWTwhich is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using theint"|" operator) two or more of thoseSWTstyle constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.- Parameters:
parent- a composite control which will be the parent of the new instance (cannot be null)style- the style of control to construct- Throws:
IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the parent is null
SWTException-- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
- ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

addSelectionListener
Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in theSelectionListenerinterface.widgetSelectedis called when the user changes the control's value.widgetDefaultSelectedis typically called when ENTER is pressed.- Parameters:
listener- the listener which should be notified- Throws:
IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the listener is null
SWTException-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

checkSubclass
protected void checkSubclass()Description copied from class:WidgetChecks that this class can be subclassed.The SWT class library is intended to be subclassed only at specific, controlled points (most notably,
CompositeandCanvaswhen implementing new widgets). This method enforces this rule unless it is overridden.IMPORTANT: By providing an implementation of this method that allows a subclass of a class which does not normally allow subclassing to be created, the implementer agrees to be fully responsible for the fact that any such subclass will likely fail between SWT releases and will be strongly platform specific. No support is provided for user-written classes which are implemented in this fashion.
The ability to subclass outside of the allowed SWT classes is intended purely to enable those not on the SWT development team to implement patches in order to get around specific limitations in advance of when those limitations can be addressed by the team. Subclassing should not be attempted without an intimate and detailed understanding of the hierarchy.

removeSelectionListener
Removes the listener from the collection of listeners who will be notified when the control is selected by the user.- Parameters:
listener- the listener which should no longer be notified- Throws:
IllegalArgumentException-- ERROR_NULL_ARGUMENT - if the listener is null

setBackground
Description copied from class:ControlSets the receiver's background color to the color specified by the argument, or to the default system color for the control if the argument is null.Note: This operation is a hint and may be overridden by the platform.
- Overrides:
setBackgroundin classControl- Parameters:
color- the new color (or null)
-
setEnabled
public void setEnabled(boolean enabled) Description copied from class:ControlEnables the receiver if the argument istrue, and disables it otherwise. A disabled control is typically not selectable from the user interface and draws with an inactive or "grayed" look.- Overrides:
setEnabledin classControl- Parameters:
enabled- the new enabled state
-
setFont
Description copied from class:ControlSets the font that the receiver will use to paint textual information to the font specified by the argument, or to the default font for that kind of control if the argument is null. -
setForeground
Description copied from class:ControlSets the receiver's foreground color to the color specified by the argument, or to the default system color for the control if the argument is null.Note: This operation is a hint and may be overridden by the platform.
- Overrides:
setForegroundin classControl- Parameters:
color- the new color (or null)
-
setDate
public void setDate(int year, int month, int day) Sets the receiver's year, month, and day in a single operation.This is the recommended way to set the date, because setting the year, month, and day separately may result in invalid intermediate dates.
- Parameters:
year- an integer between 1752 and 9999month- an integer between 0 and 11day- a positive integer beginning with 1- Throws:
SWTException-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
- Since:
- 3.4
-
setDay
public void setDay(int day) Sets the receiver's date, or day of the month, to the specified day.The first day of the month is 1, and the last day depends on the month and year. If the specified day is not valid for the receiver's month and year, then it is ignored.
- Parameters:
day- a positive integer beginning with 1- Throws:
SWTException-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
- See Also:
-
setHours
public void setHours(int hours) Sets the receiver's hours.Hours is an integer between 0 and 23.

The sequence of key strokes, button presses and/or button releases that are used to request a pop up menu is platform specific.Note: Disposing of a control that has a pop up menu will dispose of the menu. To avoid this behavior, set the menu to null before the control is disposed.
-
