Class FontMetrics
java.lang.Object
org.eclipse.swt.graphics.FontMetrics
Instances of this class provide measurement information
about fonts including ascent, descent, height, leading
space between rows, and average character width.
FontMetrics are obtained from GCs
using the getFontMetrics() method.- See Also:

equals
Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. -
getAscent
public int getAscent()Returns the ascent of the font described by the receiver. A font's ascent is the distance from the baseline to the top of actual characters, not including any of the leading area, measured in points.- Returns:
- the ascent of the font
-
getAverageCharacterWidth
public double getAverageCharacterWidth()Returns the average character width, measured in points, of the font described by the receiver.- Returns:
- the average character width of the font
- Since:
- 3.107
-
getAverageCharWidth
Deprecated.Use getAverageCharacterWidth() insteadReturns the average character width, measured in points, of the font described by the receiver.- Returns:
- the average character width of the font
-
getDescent
public int getDescent()Returns the descent of the font described by the receiver. A font's descent is the distance from the baseline to the bottom of actual characters, not including any of the leading area, measured in points.- Returns:
- the descent of the font
-
getHeight
public int getHeight()Returns the height of the font described by the receiver, measured in points. A font's height is the sum of its ascent, descent and leading area.- Returns:
- the height of the font
- See Also:
-
getLeading
public int getLeading()Returns the leading area of the font described by the receiver. A font's leading area is the space above its ascent which may include accents or other marks.- Returns:
- the leading space of the font
-
hashCode
public int hashCode()Returns an integer hash code for the receiver. Any two objects that returntruewhen passed toequalsmust return the same value for this method.
