Set an event handler for paint events. The implementation uses an intermediate buffer for non-flickering redraws. The device context (DC) is always cleared before the paint handler is called. The paint handler also gets the currently visible view area as an argument (adjusted for scrolling). Note: you can not set both a windowOnPaintRaw and windowOnPaint handler!

Set an event handler for raw paint events. Draws directly to the paint device context (PaintDC) and the DC is not cleared when the handler is called. The handler takes two other arguments: the view rectangle and a list of dirty rectangles. The rectangles contain logical coordinates and are already adjusted for scrolled windows. Note: you can not set both a windowOnPaintRaw and windowOnPaint handler!

Set an event handler for GCDC paint events. The implementation uses an intermediate buffer for non-flickering redraws. The device context (GCDC) is always cleared before the paint handler is called. The paint handler also gets the currently visible view area as an argument (adjusted for scrolling). Note: you can not set both a windowOnPaintRaw and windowOnPaint handler!

Create a new Timer that is attached to a window. It is automatically deleted when its owner is deleted (using windowAddOnDelete). The owning window will receive timer events (windowOnTimer). Broken! (use 'windowTimerCreate'\/'timerOnCommand' instead.)

Create a new TimerEx timer. It is automatically deleted when its owner is deleted (using windowAddOnDelete). React to timer events using timerOnCommand.

Set an event handler that is called on a timer tick. This works for TimerEx objects.

Get the current timer event handler.

appRegisterIdle interval handler registers a global idle event handler that is at least called every interval milliseconds (and possible more). Returns a method that can be used to unregister this handler (so that it doesn't take any resources anymore). Multiple calls to this method chains the different idle event handlers.

Pass the event on the next wxWidgets event handler, either on this window or its parent. Always call this method when you do not process the event. (This function just call skipCurrentEvent).

Pass the event on the next wxWidgets event handler, either on this window or its parent. Always call this method when you do not process the event. Note: The use of propagateEvent is encouraged as it is a much better name than skipCurrentEvent. This function name is just for better compatibility with wxWidgets :-)

Do something with the current event if we are calling from an event handler.

Installs an init handler and starts the event loop. Note: the closure is deleted when initialization is complete, and than the Haskell init function is started.

Attach a Haskell value to an object derived from EvtHandler. The IO action executed when the object is deleted.

Set a generic event handler on a certain window.

Set a generic event handler on a certain window. Takes also a computation that is run when the event handler is destroyed -- the argument is True if the owner is deleted, and False if the event handler is disconnected for example.

Type synonym to make the type signatures shorter for the documentation :-)

Sets a generic event handler, just as evtHandlerOnEventConnect but first disconnects any event handlers for the same kind of events.

Sets a generic event handler on an EvtHandler object. The call (evtHandlerOnEventConnect firstId lastId eventIds state destroy handler object) sets an event handler handler on object. The eventhandler gets called whenever an event happens that is in the list eventIds on an object with an Id between firstId and lastId (use -1 for any object). The state is any kind of Haskell data that is attached to this handler. It can be retrieved via unsafeGetHandlerState. Normally, the state is the event handler itself. This allows the current event handler to be retrieved via calls to buttonGetOnCommand for example. The destroy action is called when the event handler is destroyed. Its argument is True when the owner is deleted, and False if the event handler is just disconnected.
