byo, a reply to your mail . the in fact the wxsbitmapbutton.h is not missing , in contract , I add wxsbitmapbutton.cpp accidentally , I have not coded the bitmapbutton widget . Anyway , I shall add the wxsbitmapbutton.h later.
One thing that I notice in the wxSmith.cbp , both in "new" and HEAD version, miss out the host application setting .. Any purpose of taking of the that ? I could only run the wxSmith project when the host application is set.
