Not normally using the "Lib" Im confused.
I put a tabcontrol on my hWnd and a tabitem for the tabcontrol then
created a groupbox and added a treeview control to this groupbox.
How come I can not have a popup for this treeview control?

Ok. Just let me get this straight.
You called the popup() routine, specifying which popup menu you wanted, and
where it was to be
displayed, and nothing happened. Is that right?
Maybe you could give us more of hint about what you actually did and what
actually happened (as
opposed what didn't happen).

Hello again Derek,
I really thought my explanation two post ago was quit good but
what better way to do this than to actually give you code that doesnt work...
You should be able to run the demo and right click on the treeview for a popup
menu
but this doesnt happen.

Okay, now I see the problem. I guess you were expecting win32lib to show the
popup menu when the
user clicked the right-mouse button (I suppose) in the treeview?
This is not how it is designed to work.
You must detect the triggering mechanism and explicitly call popup() to display
the menu. The
problem with letting win32lib do this is it doesn't know what the trigger
mechanism will be, nor
does it know where on the screen you want the menu to display.
For example, you might want different popup menus to display for Ctrl-RButton,
and Alt-RButton. And
do you want them directly under the mouse pointer? Or maybe shown in such a way
that it doesn't
obscure the control underneath. May you need it relative to the top-left corner
of the control?
There are just too many varaitions for me to make an educated guess.
Popup menus are not designed to be associated with any specific control. It is
better to have the
Window own them. Look at the popup menu example program that comes with win32lib
for some more
variations on a theme.
