[GD-Windows] Propagating messages from child to parents

[Brian H. <ho...@bo...>]

Let's say I make a toolbar window and add a slider to it.  The slider 
will automatically send messages to the toolbar window, but I want 
those slider messages to get to the application.  Is there a standard 
way of doing this (or does a toolbar automatically propagate child 
messages upstream if it doesn't understand them?).

Thanks,

Brian
