Question:
I have a class derived form TTreeWindow as a child to a
TPaneSplitter (very much like the Explorer). The messages
(TVN_...) from my window seem to be rooted to the parent
window, where I can catch them without problem. Is it possible
to respond to the messages within the tree window ?
Answer:
Yes it is. It is a little trick that will work for all Child
windows that want to respond to parent caught messages. When
you define your Response table, set the events control id to
UINT_MAX (or -1) like so:
EV_...(UINT_MAX, handler)
