You can override containsPoint(x, y) to return true in the areas where the
figure *does* paint.

Can you select it if you "setOpaque(true)" it ?

I suppose you have already tried it but who knows...just to be sure...

I believed that the opacity of a Figure has only to do with weither or n=
ot =

the
background is filled with the background color before painting the =

Figure...
assuming that, I don't see any reason the opacity of a Figure would have=

something to do with the selectability of its EditPart...

But as always I may be wrong...

I code like below in Figure java file

public boolean containsPoint(int x, int y) {
Rectangle clientArea = getClientArea();
if (((clientArea.x < x)&& (clientArea.x + clientArea.width > x))
&& ((clientArea.y < y)&& (clientArea.y + clientArea.height >
y)))
{
return true;
} else
return super.containsPoint(x, y );

}



But not working.

Am I Correct?

Does you figure use a local coordinate system or zoom? getClientArea would
be the wrong method to call in that case, since its in the children's
coordinates. Otherwise I can't think of anything.

Hello Randy,

My Figure is using local coordinate system.

So the code is incorrect. You should use
getBounds().getCropped(getInsets()).contains(x, y);
