Chevron for deskband does not show as pushed.

[Matt]

Hello, I catch the RBN_CHEVRONPUSHED notification. When finished I return 0.
The problems would be that the chevron does not display in a pushed state
when I click it with the mouse though everything else seems fine. How can I
fix it?
Thanks from Matt.

After processing, return DefWindowProc(....) instead of 0.

If I do that a strange rectangular popup window appears. It looks as though
a pupup menu needs to be created during the processing of this notification
and then return without calling DefWindowProc(...) to prevent the strange
window from appearing.

Thanks

According to
http://msdn.microsoft.com/library/en-us/shellcc/platform/commctls/faq/ietoolbar.asp?frame=true#handle_chevrons,
it's intended that you call TrackPopupMenu. You may be able to substitute
your own popup window, but I suspect you'll need to keep TrackPopupMenu's
blocking behavior.

In other words, the chevron will be drawn pushed, you'll be sent
RBN_CHEVRONPUSHED, and as soon as you return the chevron is drawn flat
again.

And you're most likely right that DefWindowProc is not necessary, sorry for
the bad tip.
