38/// Wrapper for X window
39/**
40 * Example:
41 * FbWindow window(0, 10, 10, 100, 100, ExposeMask | ButtonPressMask); \n
42 * this will create a window on screen 0, position 10 10, size 100 100 \n
43 * and with eventmask Expose and ButtonPress. \n
44 * You need to register it to some eventhandler so you can catch events: \n
45 * EventManager::instance()->add(your_eventhandler, window); \n
46 * @see EventHandler
47 * @see EventManager
