How to detect (subscribe to) messages that causes screen repaint
Hello, Can someone please point me to some documentation/samples on how to do the following: I have to detect events (messages) that are issued when any of attached screens (one or possibly more of them) will be repainted (partially or completely). So any key press, new window, resize window, mouse move etc. What I am trying is to write a simple VNC viewer (server) for Linux/Android and I have not yet managed to figure out how to subscribe to such events in order to get 'paint' message and affected rectangular area. Thank you in advance ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
