The first issue is that the title bar flickers between Prof-UIS and old school classic windows when ever you drag the window around or resize it.  And if you change the text in the title bar at regular intervals it will sometimes appear (drawn) like classic windows until I interact with the menu or toolbar.

The second issue is that I have a dialog derived from CExtResizableDialog and I have several controls like a slider, etc. all of which are surrounded by a Group Box.  When the slider is moved the Group Box (which has a control attached because i change the text periodically while using the dialog) flickers.  it’s not just once in a blue moon it’s the entire time I’m dragging any of the 5 sliders in the dialog around.  Inside and outside the boundary of the group box.

These seem related somehow.  Like Windows is still rendering the window whatever way it used, but then Prof-UIS jumps in and paints over that.

Regardless, how can i make the flickering stop?

1) Your dialog template resource has both WS_CLIPCHILDREN|WS_CLIPSIBLINGS styles.

Yes.



2) The Z-order of all the group boxes should be larger than the Z-orders of all the controls "inside" groupboxes.

Yes.

The dialog controls should also have the WS_CLIPCHILDREN|WS_CLIPSIBLINGS styles set on, including group boxes.
Do you have any DirectX/OpenGL/Video output in your dialog? If yes, then the hardware accelerated output should be performed in a standalone window create as a child of your dialog.

It did not fix the issue.  I strongly believe this issue is related to the title bar issue.  I have managed to alleviate the flickering int he dialog by only calling SetWindowText() on SB_ENDSCROLL.  But the title bar could changed as often as once a second.

Then we need your help in reproducing this flickering issue with any of our sample applications or with some simple test project.

How should I go about getting the binary to you?  Email?

You can contact us by email at support@prof-uis.com.

Okay, I’m sorry it took so long.  I found an application that could be modified easily enough.  In Prof-UIS sample FunnyBars, add the following code to the end of the _UpdateHotBar function:

CString str;
    srand((unsigned int)time(NULL) ˆ clock());
    str.Format("This is a random number: %d",rand());
    this->m_wndBoxBrightness.SetWindowText(str);
    str.Format("Another random number: %d",rand());
    this->m_wndBoxFont.SetWindowText(str);

You’ll see that as you drag the brightness slider around the group boxes for Brightness and Font flicker.  The flickering is noticeable when using any theme but is most noticeable when using the Office 2007 Obsidian and Office 2010 Black.

Thank you for reporting this issue. To fix it, please update the source code for the following method:

LRESULT CExtGroupBox::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
#if (defined WM_UPDATEUISTATE)       
            ASSERT( WM_UPDATEUISTATE == 0x0128 );
#endif
            // WM_UPDATEUISTATE causes repaint without WM_PAINT, so we eat it
            if( message == 0x0128 )
                        return 0;
            if(                     message == WM_SETTEXT 
                        ||           message == WM_ENABLE
                        
                        )
            {
                        SetRedraw( FALSE );
                        LRESULT lResult = CButton::WindowProc(message, wParam, lParam);
                        SetRedraw( TRUE );
                        Invalidate();
                        UpdateWindow();
                        return lResult;
            }
            if( message == WM_PRINT || message == WM_PRINTCLIENT )
            {
                        CDC * pDC = CDC::FromHandle( (HDC)wParam );
                        CRect rcClient;
                        GetClientRect( &rcClient );
                        DoPaint( pDC, rcClient );
                        return (!0);
            }           
            return CButton::WindowProc(message, wParam, lParam);
}

This fix worked.  Thank you.

Any movement on the non-client window title bar redraw issue?

Still didn’t reproduce the window caption flicker. We used the modified version of the PageContainer sample application where we added the following code into the beginning of the CMainFrame::PreTranslateMessage() message:

   if( pMsg->message == WM_TIMER && pMsg->hwnd == m_hWnd && pMsg->wParam == 111 )
            {
                        static unsigned long garbage = 0;
                        CString str;
                        str.Format("This text has been set %d times...",garbage++);
                        SetWindowText(str);
                        return TRUE;
            }

We started the timer in the following method:

void CMainFrame::OnSetFocus(CWnd* pOldWnd)
{
            pOldWnd;
            // forward focus to the view window
CView * pView = GetActiveView();
            if( pView != NULL )
                        pView->SetFocus();

            SetTimer( 111, 200, NULL );
}

I never tried it with PageContainer because it doesn’t accurately represent our application which is an MDI application with one or more threads that that signal a window title change.  The header and source file I posted previously is almost exactly what we’re doing.  That has to work.

In the MDI application, we instantiate the App then create a child window that we maximize immediately.  So all the user sees a single window filling their entire screen.  Now at any instant we could change the window text.  For the sample I posted earlier, I chose 1 second interval to demonstrate the issue in an efficient manner.  What you should see if you double click the title bar is the window shrink slightly, then when you click maximize the window fills the screen again and the titlebar will be redrawn like old school windows.  If you cannot reproduce the bug then I’ll go so far as to screen grab or FRAPS the event and send it to you.

Keep in mind that this isn’t a consistent event, but it happens frequently enough that it’s very, very noticeable.

It would be very helpful if you show us how to reproduce this issue using any of our sample apps.

"I never tried it with PageContainer because it doesn’t accurately represent our application which is an MDI application with one or more threads that that signal a window title change.  The header and source file I posted previously is almost exactly what we’re doing.  That has to work."

From April 23rd, 2010:

I had some spare time while I was waiting for an answer so I fooled around with the "MDI" sample project.  Copy the following code into the project, file->new, maximize the child window, maximize the main window.  What you should see is the title bar turning into classic windows (or whatever theme you have on your PC) and staying that way.

Any idea if something similar will fix the title bar repainting issue?  Can I find a spot to make the same mod to ensure the Title bar is redrawn properly when we use mainFrame->SetWindowText()?

We checked the title bar text changing in Prof-UIS 2.89 and it’s OK. The older Prof-UIS versions may require sending the WM_NCPAINT message after changing window text.

Should i just SendMessage(WM_NCPAINT) after I change the title text?  Or is their a tighter way to make sure this bug is fixed?

To sending a WM_NCPAINT message is enough. Please note, this issue with window text changing is gone in the latest Prof-UIS version.

Please check the following:

1) Your dialog template resource has both WS_CLIPCHILDREN|WS_CLIPSIBLINGS styles.

2) The Z-order of all the group boxes should be larger than the Z-orders of all the controls "inside" groupboxes.

I had some spare time while I was waiting for an answer so I fooled around with the "MDI" sample project.  Copy the following code into the project, file->new, maximize the child window, maximize the main window.  What you should see is the title bar turning into classic windows (or whatever theme you have on your PC) and staying that way.

Some additional information: It’s an MDI application but only running one child window (document), when the entire window (mainframe) is smaller than the screen (not maximized) the title bar is fine (almost always, 99.9%)  When the window is maximized it’s constantly painting the title bar wrong.  When the mainframe is maximized but the document (child window) is not maximized the title bar is fine even when the window text is changed.  It only seems to be an issue when both the main window is maximized and the child window within it is maximized.  This also happens to be the normal state of the application while it’s being used.
