Hello everybody,
In GEF, Normally, the connections are drawn on top of the diagrams.
Therefore, diagrams can get overlapped with connections. But i want the
connections to go under the diagrams. How can I put them into the
background?
I tried overriding the createPrintableLayers in a class that inherits from
ScalableFreeformRootEditPart.
protected LayeredPane createPrintableLayers() {
FreeformLayeredPane layeredPane = new FreeformLayeredPane();
layeredPane.add(new ConnectionLayer(), CONNECTION_LAYER);
layeredPane.add(new FreeformLayer(), PRIMARY_LAYER);
return layeredPane;
}
And i also set the viewer's root edit part to an instance of the class
that extends ScalableFreeformRootEditPart.
Diagrams are made up of some polygon and inside the polygon, at the centre
there is image. With the approach described above, the portion of the
connection that gets overlapped with the image goes under the image and is
not seen. But remaining portion of the connection is still on top of the
polygon.
Therefore, Partly, the connections are on top of diagram.
Please help me in this problem. Any links, source examples would also be
of great help to me
Thanks,
Best Regards
Shruthi

Are you sure your polygon is not just transparent? Let's see a screenshot.

As I suspected, your figures are transparent. So, of course, you'd see
whatever's underneath them. IFigure#setOpaque(true) should do the trick.
Ensure that any custom figures you might have invoke super.paintFigure().
For Shapes (such as RectangleFigure), setFill(true) should be sufficient.
