I'm using wxhaskell 0.10.3 with ghc 6.8.2 on Windows XP Pro. I'm trying to figure out how to change the content of a frame dynamically. The program shown below has several problems: * The initial text is garbled (a combination of "Screen 1" and "Screen 2"). * The button label doesn't change when first clicked. * Nothing changes on subsequent button presses. Any ideas?
> module Main where > > import Graphics.UI.WX > > main = start gui > > gui = do > f <- frame [text := "Test 1"] > p <- panel f [] > t1 <- staticText p [text := "Screen 1"] > b1 <- button p [text := "switch to 2"] > t2 <- staticText p [text := "Screen 2"] > b2 <- button p [text := "switch to 1"] > set b1 [on command := switch f p t2 b2] > set b2 [on command := switch f p t1 b1] > switch f p t1 b1 > > switch f p t b = set f [layout := fill $ container p $ margin 10 $ >column 5 [widget t, widget b]] ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
