Comment #16 on issue 19 by daniel.schoepe: Investigate a way to allow contrib extensions to use compositing. http://code.google.com/p/xmonad/issues/detail?id=19 The advantage of handleEventHook is that you also receive events that would otherwise be handled by xmonad. Layouts only receive unhandled events. State could be done by using an IORef. I also submitted a patch a while ago that adds arbitrary other state to XState that can be used by extension, to avoid this abuse of the layoutHook, which might be suitable for this. I don't know what you mean by actions not having a way to receive Events: If you mean something like a callback on a specific event that can be done with handleEventHook or a layout modifier(by passing around an IORef these actions can also maintain state between calls). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
