Custom MDI childwnd problem

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

   Hi,

In my application, I have a MDI child window (and only one).
This child frame is derived from CMDIChildWnd to draw custom informations in its title bar (display buttons, dynamic informations, ...), overwritting the "OnNcPaint()" function..

It works fine, but when I move the window with the mouse, my title bar disappears.

It is very annoying.

I already modified the CXTPSkinObjectFrame::UseDefWindowProcAvail(..) method to avoid the "return FALSE;" :
if (HasCaption()) 
    return FALSE;

if (GetExStyle() & WS_EX_MDICHILD)  
    return FALSE;

Withou that, my title bar is never drawn.

Here are two screen captures explaining the problem:

When I run the application:

Just after moving a little the child window:

Have I to modify another part of the XTP code to get my title bar all the time?

Thank you.

	Hi, if you manually draw this window better just call XTPSkinManager()->Remove(m_hWnd) to not skin it.
