How can I draw a selection frame in a composite ?

What I'm trying to do:
I have a composite containing controls. When pressing down the left
mouse button and moving the mouse a selection frame should be displayed
(like in Windows explorer).

Problems:
1. Acording to a statement from Steve Northover (from early 2004) it is
not possible to draw onto the child controls.

2. I can't get the mouseevents when the mouse is above a children. The
events are delivered to the children in that case.

Any suggesstions ?

Regards,
Yves

Have you investigated the class Tracker? This class is used to do rubber
banding.
