Hi - can anyone tell me how I can go about changing the background color of
my palette (interested in a white background) - thanks, Barry.

Hi Barry,

To me this seems not an easy thing to do, it's straight-forward, but
requires a lot of work. The colors for palette entries are hard coded in
palette edit parts classes under
org.eclipse.gef.internal.ui.palette.editparts. This means they are not
supposed to be used by clients. Hence you'll have to extend
PaletteEditPartFactory to provide your own edit parts and create them
based on the edit parts in the GEF's internal package above. In your edit
parts you'll be able to provide custom colors for the edit parts' figures.
The customized edit part factory can be plugged to the PaletteViewer. This
could be done in PaletteViewerProvider#configurePaletteViewer().
You can try this, unless someone has a better idea of how to implement
custom colours for palette.

Cheers,
Alex

Hi Alex,

That does seem like alot of work. If all else fails, I will certainly give
it a try - Thanks alot for the explanation. Does anyone else know of a
simpler solution?
thanks - Barry

Hi,

thats easy....

In DiagramEditPart:

protected IFigure createFigure() {

ConnectionLayer connLayer = (ConnectionLayer) getLayer(LayerConstants.CONNECTION_LAYER);
connLayer.setConnectionRouter(new ManhattanConnectionRouter());

return new DiagramFigure();
}

// use your own Figure for the Diagram

public class DiagramFigure extends FreeformLayer {

public DiagramFigure() {

setBorder(new MarginBorder(3));
setLayoutManager(new FreeformLayout());
setBackgroundColor(ColorConstants.lightGray);
// Create the static router for the connection layer
}

/** Paint this figure. */
public void paintFigure(Graphics graphics) {
graphics.setAntialias(SWT.ON);

graphics.setForegroundColor(ColorConstants.lightGray);

graphics.setBackgroundColor(ColorConstants.white);
graphics.fillGradient(getBounds(), true);

}
}

Hope this helps,
peter
