Dynamic pane re-pin painting bug?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey all,

I am running into an issue that happens when a pane is docked and then
unpinned, then the user clicks on the tab that is created for the pane
and pins it again.  The problem is that as soon as the user clicks
on the pin button to repin the pane, a duplicate of the pane is drawn
just to the right of the pane itself.  If you cause the window to
be repainted (resize it for example) then the "garbage pane" disappears
and all looks normal again.   I have already tried adding
WS_CLIPCHILDREN and WS_CLIPSIBLINGS to the frame and view - didn't
help.  The pane contains no control - I originally had a list box
in it but removed it just to make sure it wasn't causing the bug. 
I need some help here.

I took screenshots of the steps involved.

1.  User clicks on the push pin to unpin the pane

2.  Unpin works great, user clicks tab

3.  Pane is unpinned correctly, user clicks the push pin to re-pin the pane

4.  Pane is re-pinned with the "garbage pane" painted over the view

	Okay I found out what was going on. Since my view is (obviously from the screenshots) a CFormView, the dialog it contains also needs to have the WS_CLIPCHILDREN and WS_CLIPSIBLINGS styles. When I added to those the CFormView's Dialog, everything worked fine.
