Hi,

I need to add/remove buttons to a floating CExtToolControlBar.
After calling InsertButton or remove button I try to notify the toolbar
that its layout changed:

CFrameWnd *pParent = GetParentFrame();
if (pParent)
{
    pParent->RecalcLayout();
    pParent->Invalidate();
    pParent->RedrawWindow();
}

But the upper part (which contains the title and the small ’x’) stays at the old size until I move the mouse somewhere over the toolbar.

In another docked toolbar I change the button text from time to time. But RecalcLayout does not work there, too. So the text ’runs’ into the next toolbar button.

What do I miss here?

Thanks!
Gregor

In some cases the non-client area of floating mini frame window should be re-painted manually. You should invoke the following code:

CFrameWnd * pFrame = GetParentFrame();
      if( pFrame != NULL )
      {
            ASSERT_VALID( pFrame );
            pFrame->RecalcLayout();
            if( pFrame->IsKindOf( RUNTIME_CLASS( CMiniFrameWnd ) ) )
                  pFrame->SendMessage( WM_NCPAINT );
      }
