CXTPStatusBar not subclassed from CStatusBar

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am working with a large existing application, making use of Codejock in various places.  In a few places, I would like to replace CStatusBar usage with CXTPStatusBar to take advantage of its extended capabilities.  I assumed that the XTP control would derive from the MFC control, and that I could change the single internal API I have to obtain the status bar control to cast the CXTPStatusBar to a CStatusBar, and that most places in my code base could continue to function just fine through the CStatusBar interface without any editing on my part.  However, that fell apart once I realized that CXTPStatusBar doesn't derive from CStatusBar. 

Is there any way to handle this without massive edits to my code base?

	Hello, Yes, CXTPStatusBar is not derived from CStatusBar, but it has all same methods. Just replace CStatusBar to CXTPStatusBar, think it will work without any changes.

	It doesn't have the exact same methods. CXTPStatusBar::SetPaneText asks for a CString& rather than LPCTSTR. The proprietary object I use for most of my text handling can automatically cast to LPCTSTR. To get CString& I will have to edit code. Also, if (OK, when) I replace CStatusBar with CXTPStatusBar, I will need to change every pointer declaration that deals with CStatusBar and make the change there, too. That's a bummer, and I'm wondering why you didn't just subclass CStatusBar and avoid that kind of issue.
