What window message do I need to handle in other to handle mouse clicks on non region of a window? Specifically I need it to know when a user right clicks on a tab control so that I can display a floating menu with which the user can close one or more tabs as it is done in moilla firefox.

Sorry about the omission.I meant "non-client region of a window"

Those are special separate non-client messages: http://msdn.microsoft.com/en-us/library/windows/desktop/ms645618%28v=vs.85%29.aspx[^].

(In the MSDN article referenced above, look at the left part for all messages named as WM_NC*.)

However, you should understand what the client area is: http://msdn.microsoft.com/en-us/library/windows/desktop/dd162743%28v=vs.85%29.aspx[^].

In particular, tab areas are not non-client. Non-client area is everything between client rectangle and outer window bounds: borders, title bars…

If I subclass the Tab control won't it receive WM_NC* that is meant for it?

I don't think the tab has any non-client areas, or maybe this area is just the thin border around. It's more like button.
The tab notifications are described here:

P.S.: and of course subclassing cannot make a client area non-client or visa versa. :-) Windows just look at window object and its "window class" in the sense of the Window API (non-OOP), as I tried to explain recently.

So how would you suggest I monitor right clicking on the tab control

Sergey Alexandrovich Kryukov 6-Feb-14 8:25am

As described in the MSDN article referenced above...

Perhaps you should see this:

It says "How to create status bar". How is that related...

Sorry there was a mixup. I think you should see this:

Okay, and..?
Didn't I answer on how to capture tab events?
