Method Detail

paintImpl

protected void paintImpl(org.eclipse.swt.events.PaintEvent e,
                         GlyphGC gc)

Description copied from class: Glyph

Implement this if you don't want to worry about AffineTransforms. Your graphics will be rasterized and have an AffineTransform applied to them

Overrides:

paintImpl in class Glyph

getEdge

protected int getEdge(int x,
                      int y)

getBoundsImpl

protected org.eclipse.swt.graphics.Rectangle getBoundsImpl()

Specified by:

getBoundsImpl in class Glyph

Returns:

your bounds without having the AffineTransform applied to them

pointInsideImpl

protected boolean pointInsideImpl(int x,
                                  int y)

Description copied from class: Glyph

Return if the point is inside your glyph without the AffineTransform applied

Specified by:

pointInsideImpl in class Glyph

mouseDoubleClick

public void mouseDoubleClick(org.eclipse.swt.events.MouseEvent arg0)

Specified by:

mouseDoubleClick in interface org.eclipse.swt.events.MouseListener

mouseDown

public void mouseDown(org.eclipse.swt.events.MouseEvent me)

Specified by:

mouseDown in interface org.eclipse.swt.events.MouseListener

mouseUp

public void mouseUp(org.eclipse.swt.events.MouseEvent arg0)

Specified by:

mouseUp in interface org.eclipse.swt.events.MouseListener

getDeltaLat
