I was looking at the source of the class
org.eclipse.gef.editparts.GridLayer. If you extend this class you could
change the colour and how it is drawn.
If you have a FreeformGraphicalRootEditPart then you could extend this
class and over-ride this method:
protected GridLayer createGridLayer() {
return new GridLayer();
}
to:
protected GridLayer createGridLayer() {
return new MyGridLayer();
}
and then create a MyGridLayer class which extends GridLayer and
over-ride the method:
protected void paintGrid(Graphics g) {
FigureUtilities.paintGrid(g, this, origin, gridX, gridY);
}
to:
protected void paintGrid(Graphics g) {
customPaintGrid(g, this, origin, gridX, gridY);
}
and write your own customPaintGrid() method based on the one at
FigureUtilities.paintGrid()
