Hi,
 
I have also problem with CXTButton added to status bar. In this same status bar i have a second pane that shows current cursor position.
My button is declared as CXTPNoFlickerWnd<CXTButton> m_wndStatusButton. And when I am moving mouse the button is flickering.


If anybody have any ideas i would be appreviative for help.
 
Thanks
Bastian

Hi,
 
It doesn't help. My code is very simple.When I am resizing windows a view inside Workspace view still flickers. I didn't change code very much. Just instead your CScrollRichEdit class I am using normal CView class.
 

void CMainView::OnPaint()

{

    CPaintDC dc( this );

    CRect rc;

    GetClientRect( &rc );

    CXTMemDC MemoryDC( &dc, &rc );

    rc.DeflateRect( 16, 16, 16, 16 );

    MemoryDC.FillSolidRect( &rc, RGB( 255, 0, 0 ) );

}

 

BOOL CMainView::OnEraseBkgnd( CDC *pDC )

{

    return TRUE;

}

Thanks for help.
