Change the color of the selection frame [message #221404]

I have a GEF editor based on the logic - example.

My problem is, that the background of the GraphicViewer has to be black.

Therefore one can't see the frame that the selection-tool draws around

a selected part and the handles are not shown with verry good contrast

( black handles with thin white frames on black background ).

My Question is: Where and how can I change the color of the frame

and the handles that are drawn around a selected part.

Thanks in advance

Look in class ResizableEditPolicy/NonResizableEditPolicy.

That worked perfectly:

/**
* @return
* @see org.eclipse.gef.editpolicies.ResizableEditPolicy#createSelec tionHandles()
*/
@Override
protected List createSelectionHandles() {

List l = super.createSelectionHandles();
for (Object obj : l) {
if(obj instanceof AbstractHandle) {
AbstractHandle handle = (AbstractHandle) obj;
Border border = handle.getBorder();
if(border instanceof LineBorder) {
LineBorder lborder = (LineBorder) border;
lborder.setColor(ColorConstants.red);
}
}
}

return l;
}

Thanks a lot.
