How is it possible to get the grid on the image?

Thanks for your help.

Hi,

look in your RootEditPart, there is a layer called GRID_LAYER. This layer
should be added after your layer with the background image is added.

Greets,

Ok, i added a grid_layer to the figure, which paints the image. e.g.

MyEditPart(){
IFigure createFigure() {
Figure f = new FreeformLayer() {
protected void paintFigure(Graphics graphics) {
graphics.drawImage(foo_image,0,0);
}
}
return f;
}
}

The grid can be toggled with

IAction showGrid = new ToggleGridAction(getGraphicalViewer());

So when i add an other grid_layer to the Figure, the grid cant be hidden
by the action.
