Hello everyone:

I am developing an application based on MFC "CMDIChildWnd" classes. I have inserted a "CXTPDockingPaneManager" in every child window and some docking panes which "CFormViews" attached on them.

The problem comes when I try to resize the CMDIChildWnd dragging it with the mouse: all the controls in the CFormsViews begin flickering while the OnSize process goes on. This gives the application a horrible final aspect and a non-professional style.

Is there any way to fix this in an easy way?

Thank you very much.

Thank you for answer me so far, Oleg.

Your solution works fine with dockink panes� flickering when the user hides or shows those panes, but I am resizing the child windows. The flickering persists during the child window resize process or even during the application resize, but NOT if I move the application dragging it around the screen. I have all my docking panes attached on the view as a tabbed window.

In Toolkit�s 9.7 samples this also happens, but due to the small amount of controls in the CFormView is almost imperceptible.

Thanks.

See sample.

Main code is:

int CProperttiesView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFormView::OnCreate(lpCreateStruct) == -1)
return -1;

ModifyStyle(0, WS_CLIPSIBLINGS | WS_CLIPCHILDREN);

return 0;
}

void CProperttiesView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();

SetScaleToFitSize(CSize(1, 1));
}

Thank you again, Oleg. The sample attached has been very useful for me.

Almost everything is now OK in my "CFormViews", but the MFC�s Group Boxes and Month Calendar Controls still flicker. Can you help me with this or it�s a MFC bug?

Best regards.

just checked - flicker anyway :(

To avoid some drawing (not flicker problems) also in properties of Group Box check "Tranparent" property...

Thank you, Oleg.

Your are giving me great support with this subject. "CXTResizeGroupBox" works terrific and almost everything is now OK, but the problem with CMonthCalendarCtrl, CSliderCtrl and some others persist. All them flicker (it would better say they flash!!!) yet and it�s kind of annoying.

Regards and congratulations for this forum�s support.
