The following is a sample 'setup' for sending a Panel data stream to DESQview as well as the code needed to create and open the Keyboard, Mouse, Window, and Object object handles. This example is designed to take various topics in the DESQview API and combine them into a usable example. The resulting window contains 18 fields selectable with the mouse or the keyboard. The data returned by DESQview with this setup allows the mouse and the keyboard to behandled as the same logical input device. Keep in mind that this is a program fragment, not a complete program. It is merely intended to demonstrate sample procedures to create a window with selectable fields using the keyboard or the mouse.
