Re: [GD-Windows] Propagating messages from child to parents

[brian s. <pud...@po...>]

You can subclass the window procedure of the toolbar so that you can 
catch the messages sent from the slider and pass them up to your app's 
wndproc (with SendMessage as someone else suggested).  I suspect that 
MFC does a lot of heavy lifting for you in this area, but I don't know 
if you're using it.  Subclassing windows isn't that hard anyway.

I think you can also create the slider with your app's window as the 
parent, and then after it's created, call SetParent to change the 
parent window to the toolbar...that might get the messages going to 
your parent while maintaining the correct hierarchy for drawing.  Kind 
of a hack though.
