Hello

There are tabbed MDI client windows which can be changed to Max, Min or normal size. After maximized one window, and then switched among client windows by clicked the title tabs, the view is drawed twinkling and not smooth. Please help me how to resolve it?

Thanks.

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
// Make sure view is maximum size to eliminate
// flicker when switching tabs.
cs.x = cs.y = 0;
cs.cx = cs.cy = 32767;

if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;

return TRUE;
}

Hello,

the best way to avoid fleeking is to inherit from CXTPTabClientWnd and to catch the WM_MDIACTIVATE message. You should then lock the redraw before calling the base class and unlock it after execution. See code below.

best regards from G�ttingen, germany

BEGIN_MESSAGE_MAP(CMainTabClientWnd, CXTPTabClientWnd)ON_WM_MDIACTIVATE()
END_MESSAGE_MAP()

void CMainTabClientWnd::OnMDIActivate(BOOL bActivate,CWnd* pActivateWnd, CWnd* pDeactivateWnd)
{
SetRedraw(FALSE);
CWnd::OnMDIActivate(bActivate, pActivateWnd, pDeactivateWnd);
SetRedraw(TRUE);

RedrawWindow( NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_ALLCHILDREN);
}
