I'm experimenting with wxHaskell, and I've got something like: main = run mainFrame mainFrame = do -- main application frame ... cbEdit <- checkBox p1 [text := "Edit Mode", on command ::= onCbEdit textlog] ... where ... It would be useful to have some convenience function, let's say, isEditing, which works out whether cbEdit is checked, or not. That way, one could just pass this in as a parameter without requiring any extra code. The problem is, I can't see how it can be done. I've tried various things in the main section, and nothing worked. I tried putting the following defintion into the where clause: isEditing = do checkedp <- get cbEdit checked return checkedp but the compiler complained that cbEdit is not in scope. I /could/ pass in cbEdit as a parameter to isEditing, but I'd rather not. ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!
