Eclipse Platform
Release 3.5

org.eclipse.swt.graphics
Class GlyphMetrics

java.lang.Object
  extended by 
org.eclipse.swt.graphics.GlyphMetrics

public final class GlyphMetrics
extends Object

Instances of this class represent glyph metrics.

The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.

Application code does not need to explicitly release the resources managed by each instance when those instances are no longer required, and thus no dispose() method is provided.

Since:
3.2

 int descent
          the descent of the GlyphMetrics
 int width
          the width of the GlyphMetrics
 
Constructor Summary
GlyphMetrics (int ascent, int descent, int width)
