Package org.eclipse.draw2d
Class SWTGraphics
java.lang.Object
org.eclipse.draw2d.Graphics
org.eclipse.draw2d.SWTGraphics
A concrete implementation of
Graphics
using an SWT
GC
. There are 2 states contained in this graphics class -- the
applied state which is the actual state of the GC and the current state which
is the current state of this graphics object. Certain properties can be
changed multiple times and the GC won't be updated until it's actually used.
WARNING: This class is not intended to be subclassed.
