I'm trying to use a single docking pane to display any number of windows.

So when someone selects something new, I'm calling Detach() then Attach() to attach the new CWnd to the tabbed pane.

This causes some weird problems.

For starters it doen't draw the new tab. This is because the selection hasn't changed, and in CXTPDockingPaneTabbedContainer::InvalidatePane

bSelectionChanged = false, so it doesn't draw the pane.

If I select another pane then back to the one, it shows it fine, although as soon as I resize the tabbed panel, it stops showing it again (just shows grey background).

I've tried calling all sorts of things... including windows functions on the hWND of the child window. I can see in Spy++ that the window does changeits parent.

Is it supposed to be supported to attach and detach windows at will from a docked pane?

p.s. - sorry, the call stack shows that the call to InvalidatePane was in the context of me resetting the pane title, nothing to do with attaching the pane.

All that seems to do is set the new parentage. It's weird that it won't then redraw.

Also, when I'm attaching the window, I only have an HWND, so I'm passing in CWnd::FromHandle(hchild) to Attach(). I see the pane only stores the hwnd, and when it wants a CWnd it calls FromHandle itself, so I presume there's no problem with what I'm doing there.
