|Okay article that fried me.
I was almost sure I couldn't pull this trick (and still thinking about it Trapping OnChildNotify ...).
I think I'll try to derive A Ctoolbar class with a wndproc handler - OnChildNotify firing messages on to my derived clistbox wndproc. It seems that might do it. All it would need is the original Window creating the toolbar.
If that fails
I'll probably just recreate my class Via CFrame, add the cListbox and toolbar. write the toolbar handler in Cframe ... and make the CFrame invisible using Defines
Still it seems that you should be able to rout the WndProc messages of a child to any handler you want. Then filter, and send unprocessed messages to the original handler.
One way or the other Thanx for your input
