WM_RBUTTONDOWN/UP vs WM_CONTEXT_MENU

[Olaf van der Spek]

Hi,

What's the exact difference between those two? To me, they seem to do the
same.

Olaf,

The WM_RBUTTONxxx messages are the basic messages generated by the
mouse driver. The WM_CONTEXTMENU message is a notification message
sent when the default message handler processes those raw messages.

The WM_CONTEXTMENU message is also send for the keyboard operations
Shift+F10, and (if you've got a new keyboard) the context menu key. So
it is the proper message to handle, rather than the mouse specific
ones.

Ok, but what if I would like to decide myself whether or not to display a
context menu or to do some other action?
Which handler should Iuse then?

Use WM_CONTEXTMENU - if you don't use that you'll miss handling the
keyboard activation method.

If you're trying to circumvent something (like the standard popup that
an edit controls has), handle WM_CONTEXTMENU, do your own code, and
don't pass that message to the default handler.
