GEF editor background image [message #244844]

Hi , every one. I have tried to set Background image on the editor by
modifying the paint method at Venueditpart(createfigur method). This
works fine but when I am drawing components I can not see them as the
layer has been over draw by the image.

Is there any way I can set the layer to the components or the anything
with image which will solve this problem.

Please..
Thanks.
RAJ

Put the image on the last(bottom) layer which you need create, because
any layer above is transparent. e.g:

overwrite org.eclipse.gef.editparts.ScalableFreeformRootEditPart

protected ScalableFreeformLayeredPane createScaledLayers() {
ScalableFreeformLayeredPane pane = super.createScaledLayers();
pane.add(new BackgroundLayer(),"BACKGROUND_IMG");
return layers;
}

on EditPart:

public void addNotify() {
IFigure bg_figure = ...
getLayer("BACKGROUND_IMG").add(bg_figure);
super.addNotify();
}
