Hi Support-Team I want to have a ControlBar with an ExtTreeCtrl inside. And it works well if create the tree without the CExtNCSB template class and with the template class it doesn’t work. But without this class I get the tree with standard scrollbar. Is there any possibility to get the ExtTreeCtrl with right theme scrollbar in a ExtControlBar? Regards

Yes.
The CExtNCSB template class controls two CExtScrollBar windows created over other window with scroll bar like non-client areas.
The CExtNSB template class is designed for inserting CExtScrollBar scroll bars into any CExtScrollWnd -based window like CExtGridWnd , CExtTreeGridWnd , CExtReportGridWnd , CExtImageEditWnd and CExtColorPaletteWnd .

So what do I need to do in a control-bar that has a grid in it?

Just create the grid window inside the control bar. The grid can be based on the CExtNSB template class or not be based on it - in any case there are no need to invoke non-default constructors.

The CExtNCSB template class creates two CExtScrollBar windows in the same z-order layer with the CExtTreeCtrl window. As a result, the CExtControlBar window contains three child windows. But the CExtControlBar window is designed to be a container for one child window only. The CExtNCSB template class can also be configured for using <b>middle container mode</code>. In this mode it creates one container window between the tree and the control bar and creates two scroll bars as children of this container window. You can instantiate the CExtNCSB < CExtTreeCtrl > object dynamically and make it using the <b>middle container mode</code> in parameters of the CExtNCSB template class constructor: // in scope of main frame class declaration:
CExtTreeCtrl * m_pWndTree;
// in main frame’s constructor
CMainFrame::CMainFrame()
: m_pWndTree( NULL )
. . .
{
. . .
m_pWndTree = new CExtNCSB < CExtTreeCtrl > ( true, true );
. . .
}
// in main frame’s destructor
CMainFrame::~CMainFrame()
{
. . .
if( m_pWndTree != NULL )
{
delete m_pWndTree;
m_pWndTree = NULL;
}
. . .
}
You should simply create the m_pWndTree window as child of the CExtControlBar window in main frame’s OnCreate() method.
