How do I add a bitmap to a pane in the CXTPStatusBar?
It seems that CXTPStatusBarIconPane plays a role in this.
Thanks for any pointers .... Stan

I came up with a solution for this.
Briefly:
Derive a BmpWnd class from CXTPStatusBarPaneWnd.
Call its Create() passing the m_wndStatusBar.
Add a pane for it: wndStatusBar.AddIndicator(ID)
Associate the window: wndStatusBar.AddControl(&m_bmpWnd,ID)
Most of the work is done in BmpWnd::DoPaint() - BitBlts that make a selected color in the bmp transparent.
-------
BTW Ultimate Toolbox has SetPaneBitmap member in its COXStatusBar which makes this easy to do. I'm migrating our application to CJ so needed to implement the equivalent. SetPaneBitmap would be a welcome addition to CXTPStatusBar or CXTPStatusBarPane
Cheers .... Stan (using XTP v11.2.2)

Hi,
Better derive from CXTPStatusBarPane and override its CXTPStatusBarPane::OnDraw
CXTPStatusBarPaneWnd class add additional window handle to draw, and it can reason of flickers.

Hi Oleg,
I tried your suggestion to move the implementation into CXTPStatusBarPane rather than using CXTPStatusBarPaneWnd. It worked as well but I had problems resolving heap corruption on application close during processing WM_NCDESTROY (using CXTPStatusBarPaneWnd, I don't see this).
Thanks .... Stan

Hi,
don't delete pane manually. It will be deleted by CXTPStatusbar. and create it dynamically.
