[news.eclipse.tools.gef] problem with repaint()

["cz" <chenzhuang2000@xxxxxxx>]

Hi, all,
I have a layer and some figures.
The figures are the children of the layer.
If i add a new figure into the children list, I want to repaint() the layer.
But, what i got is that the repaint() can only be used in the method of
paintFigrue(Graphics).

So, I try:

Display.getCurrent().timerExec(1000, new RepaintThread());

but the new figure can be added if the ClientArea is resized.

How to atuo repaint the layer when the new figure added?

Regards!
