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.
