Deeply nested controls do not resize properly

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

Hi,
In our APP we have a lot of nested CJ Controls, mostly panes, inside panes, collapsing and expanding and at the end of the chain( sometimes down to 5 levels of panes ) we have one control that is ours.  
When I resize the application( Main window ), or top levels panes, some of the controls near the end of the chain won't paint or resize properly, both CJ and our controls.

The chain is something like this

XTPFrameWindow
	XTPDockingPaneManager
	XTPDockingPaneTabbedContainer
		FrameWindow
			XTPDockingPaneManager 	
			XTPDockingPaneTabbedContainer
				(...)
	XTPDockingPaneTabbedContainer
		FrameWindow
			XTPDockingPaneManager 	
			XTPDockingPaneTabbedContainer				
				(...)

It then repeats several times, depending on the how the end user design it at runtime, I put no limitation of how deep this chain could repeat it self.

After several days of investigation I found out that probably the cause is a limitation from Windows Kernel, not a bug from my APP or CJ

http://support.microsoft.com/kb/953934

But the solution seems to require a non standard implementation. :-)

I'm not quite sure how to do it with the old MFC in Visual C++ 6.0 and Codejock 13.

Does CJ have any upgrade or any ideia for a solution ? 

Best regards,

	Found a solution, seems to be working but i'm not sure it's the right one... void CMyFrameWnd::OnWindowPosChanged(WINDOWPOS* lpwndpos) { if ( lpwndpos == &m_wndPos ) Default(); else { memcpy( &m_wndPos, lpwndpos, sizeof( WINDOWPOS ) ); PostMessage( WM_USER_POSTWINDOWPOSTCHANGED, 0, (LPARAM)&m_wndPos ); } } LRESULT CMyFrameWnd::OnPostWindowPosChanged( WPARAM w, LPARAM l ) { WINDOWPOS lpwndpos = (WINDOWPOS)l; WNDPROC wndProc = (WNDPROC)GetWindowLongPtrW(GetSafeHwnd(), GWLP_WNDPROC); LRESULT lResult = ::CallWindowProc(wndProc, GetSafeHwnd(), WM_WINDOWPOSCHANGED, 0, (LPARAM)lpwndpos); return lResult; }
