| Description | ||||||||
Event handlers are registered with setXXXHandler for a particular widget. Allthough event handlers can be unregistered explicitly, all registered widget handlers will be automatically unregistered when a widget is destroyed. When quit is called, it will close all windows, unregister all event handlers and destroy all timers. | ||||||||
| Synopsis | ||||||||
| Clean up | ||||||||
| unregisterAllWindowHandlers :: WindowHandle -> IO () | ||||||||
| Unregister all event handlers and menu handlers associated with a specific window. This function is automatically called when a window is destroyed. | ||||||||
| Timers | ||||||||
| registerTimer :: TimerHandle -> IO () | ||||||||
| unregisterTimer :: TimerHandle -> IO () | ||||||||
| getAllTimerHandles :: IO [TimerHandle] | ||||||||
| getAllTimerHandles returns list of handles for all created timers. | ||||||||
| Events | ||||||||

| setTimerDestroyDefHandler :: TimerHandle -> IO () | ||||||||
| getTimerDestroyHandler :: TimerHandle -> IO (IO ()) | ||||||||
| Windows | ||||||||
| registerWindow :: WindowHandle -> IO () | ||||||||
| registerWindow should be called by all top-level window creation functions. The windows are automatically unregistered when destroyed. | ||||||||
| unregisterWindow :: WindowHandle -> IO () | ||||||||
| getAllWindowHandles :: IO [WindowHandle] | ||||||||
| getAllWindowHandles returns list of handles for all opened windows, sorted in Z-order. | ||||||||
