Hi!
I'm using the CXTSplitterWnd and the Views are flickering A LOT!

I'm with the 1200 version, on VS2005 and WinXP SP2.

I'm appending CDialog controls inside my views (CView) and both (the CDialogs and the CViews) are being templated trought the CXTPNoFlickerWnd template class.
Inside the CDialogs also live other child dialogs, with other controls.
The CView derived class, calls to MoveWindow of the child CDialogs as a basic logic for the splitter (just for now).
Also I'm applying the fix for the Splitter related with the OnMouseMove and OnLButtonUp issues.
This how I'm initializin the controls: 

     if(_splitter == NULL)

          _splitter = new CGdxSplitterWndFixed;

     _splitter->CreateStatic(_frameContainer,2, 1);

     _splitter->ModifyStyleEx(WS_EX_CLIENTEDGE, 0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOZORDER|SWP_NOACTIVATE);

     //_splitter->SetSplitterStyle(XT_SPLIT_DOTTRACKER);

     _splitter->CreateView(0,0, RUNTIME_CLASS(CHolderView), CSize(rect.Width(), rect.Height()/2), &ccc);

     CHolderView* pView = (CHolderView*)_splitter->GetPane(0,0);

     ASSERT_VALID(pView);

     if(_report == NULL)

          _report = new CXTPNoFlickerWnd<CGdxReportViewDialog>;

     pView->setWnd(_report);

     pView->setOwner(parent);

     _report->Create(CGdxReportViewDialog::IDD, pView);

and then the show thing with the EnableThemeDialogTexture 

_report->ShowWindow(SW_SHOW);

_frameContainer->ShowWindow(SW_SHOW);

_splitter->ShowWindow(SW_SHOW);

XTPSkinManager()->EnableThemeDialogTexture(_report->GetSafeHwnd(), ETDT_ENABLE);     

and so...

How can avoid the Flickering?

Thanks!

Hi,
 
in Views catch WM_ERASEBGND and return TRUE, add WS_CLIPCHILDREN for Views and Splitter.

No, no luck.
I added the WS_CLIPCHILDREN to the splitter and to the CViews, also to the parent frame of the splitter.
Almost all child windows of the splitter are templated using the CXTPNoFlickerWnd, which returns TRUE in the WM_ERASEBGND.
Maybe you can send me an example using CDialogs inside the splitter that doesn't flicker?

Thanks!

Oleg,

 
I posted comments about CXTSplitterWnd in the Beta group quite some time ago and it seems that nothing has been changed thru 12.0.2
 
OnLButtonUp should be deleted entirely or forwarded to CSplitterWnd, and OnMouseMove should be simplified as shown below.
 

void CXTSplitterWnd::OnLButtonUp(UINT nFlags, CPoint point)

{

CSplitterWnd::OnLButtonUp(nFlags, point);

// Invalidate();

}

void CXTSplitterWnd::OnMouseMove(UINT nFlags, CPoint point)

{

CSplitterWnd::OnMouseMove(nFlags, point);

if(m_bTracking && m_bFullDrag && m_point != point)

{

OnLButtonUp(MK_LBUTTON, point);

OnLButtonDown(MK_LBUTTON, point);

RedrawWindow(NULL, NULL, RDW_ALLCHILDREN | RDW_UPDATENOW);

m_point = point;

}

}

Need remove:

OnLButtonUp(MK_LBUTTON, point);

OnLButtonDown(MK_LBUTTON, point);

Anyway it does not work correctly.

i patch it that:
void CXTSplitterWnd::OnMouseMove( UINT nFlags, CPoint point )
{
    if ( m_bFullDrag == FALSE )
    {
        CSplitterWnd::OnMouseMove( nFlags, point );
        return;
    }

    if ( GetCapture() != this )
    {
        StopTracking( FALSE );
    }

    if ( m_bTracking )
    {
        // move tracker to current cursor position
        point.Offset(m_ptTrackOffset); // point is the upper right of hit detect

        // limit the point to the valid split range
        if (point.y < m_rectLimit.top)
        {
            point.y = m_rectLimit.top;
        }
        else if (point.y > m_rectLimit.bottom)
        {
            point.y = m_rectLimit.bottom;
        }
        if (point.x < m_rectLimit.left)
        {
            point.x = m_rectLimit.left;
        }
        else if (point.x > m_rectLimit.right)
        {
            point.x = m_rectLimit.right;
        }

        if (m_htTrack == vSplitterBox || m_htTrack >= vSplitterBar1 && m_htTrack <= vSplitterBar15)
        {
            if (m_rectTracker.top != point.y)
            {
                OnInvertTracker(m_rectTracker);
                m_rectTracker.OffsetRect(0, point.y - m_rectTracker.top);
                OnInvertTracker(m_rectTracker);
            }
        }
        else if (m_htTrack == hSplitterBox || m_htTrack >= hSplitterBar1 && m_htTrack <= hSplitterBar15)
        {
            if (m_rectTracker.left != point.x)
            {
                OnInvertTracker(m_rectTracker);
                m_rectTracker.OffsetRect(point.x - m_rectTracker.left, 0);
                OnInvertTracker(m_rectTracker);
            }
        }
        else if (m_htTrack == bothSplitterBox || (m_htTrack >= splitterIntersection1 && m_htTrack <= splitterIntersection225))
        {
            if (m_rectTracker.top != point.y)
            {
                OnInvertTracker(m_rectTracker);
                m_rectTracker.OffsetRect(0, point.y - m_rectTracker.top);
                OnInvertTracker(m_rectTracker);
            }
            if (m_rectTracker2.left != point.x)
            {
                OnInvertTracker(m_rectTracker2);
                m_rectTracker2.OffsetRect(point.x - m_rectTracker2.left, 0);
                OnInvertTracker(m_rectTracker2);
            }
        }

        int htTrack = m_htTrack;
        StopTracking( TRUE );
        StartTracking( htTrack );

        if (m_point != point)
        {
            RedrawWindow(NULL, NULL, RDW_ALLCHILDREN | RDW_UPDATENOW);
            m_point = point;
        }
    }
    else
    {
        // simply hit-test and set appropriate cursor
        int ht = HitTest(point);
        SetSplitCursor(ht);
    }
}

Have you tested this with this setting enabled/disabled?

SystemParametersInfo(SPI_SETDRAGFULLWINDOWS, 0, (PVOID)FALSE, SPIF_SENDCHANGE);
vs
SystemParametersInfo(SPI_SETDRAGFULLWINDOWS, 0, (PVOID)TRUE, SPIF_SENDCHANGE);
