Thanks. I added the following lines as told. Now I am getting a window but 1) it is not circular shaped although I am using X shape extension API 2) it is not accepting any input. XNextEvent() still hangs attached is the modified program. Anything else I need to add Also, can anyone help me to understand what difference does it make if we call XSelectInput or XShapeSelectInput? Do we always need to use XShapeSelectInput if we have set a shape on the window? Or are there cases in which we would want to use XSelectInput with a shaped window?
