*propagateEvent* :: IO () Pass the event on the next /wxWindows/ 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 <http://wxhaskell.sourceforge.net/doc/Graphics.UI.WXCore.Events.html#v%3AskipCurrentEvent>). I want to do the opposite - handle the event in the frame where the expression is displayed, but not send it to whatever is handling the scroll bars My code - for the relevant windows > -- Goal Window > gp <- panel h [] > g <- scrolledWindow gp [] Do I need to nest another window inside the scrolled window ? When I perform the right-arrow action (say), I repaint g, which renders the expression appropriately. My biggest problem is that the documentation is very unclear. -- -------------------------------------------------------------------- Andrew Butterfield Tel: +353-1-896-2517 Fax: +353-1-677-2204 Foundations and Methods Research Group Director.
