Please see the program below. Originally I built and ran it in Ubuntu environment. There is a frame around the SDL window with a title in upper left corner. When my program switches operating mode or the data set being used it writes the status in the upper left (title area) of the frame using
SDL_SetWindowTitle(win1, headr)
It is a very useful feature. Now I have built the program for use with Windows. It works fine except for one thing - in Windows no frame is displawed around the SDL window. So, in Windows I don’t have the program status displayed. Can someone here tell me how to get the frame displayed around the the SDL window? When running in Ubuntu I have the frame, when running in Windows I don’t have the frame.
TIA. Bill S.
