Overview ¶
Example graceful-window-close shows how to create windows that can be closed without killing your X connection (and thereby destroying any other windows you may have open). This is actually achieved through an ICCCM standard. We add the WM_DELETE_WINDOW to the WM_PROTOCOLS property on our window. This indicates to well-behaving window managers that a certain kind of client message should be sent to our client when the window should be closed. If we *don't* add the WM_DELETE_WINDOW to the WM_PROTOCOLS property, the window manager will typically call KillClient---which will destroy the window and your X connection.
If you click inside one of the windows created, a new window will be automatically created.
The program will stop when all windows have been closed.
