gtk2hs

Hi! I tried to implement a simple counter with gtk2hs. To increase my counter I defined following event: onClicked btn $ do si <- textBufferGetStartIter tb ei <- textBufferGetEndIter tb val <- textBufferGetText tb si ei False textBufferSetText tb $ show $ (+1) $ read val But now I don't want always read the textfield to get my counter-value, I would like to save the state of my increased value and would like to pass it to the next call of the function. How can I do this? thanks Christian This is the complete code: import Gtk quitDialog :: IO Bool quitDialog = ..... main :: IO () main = do initGUI --main window win <- windowNew onDelete win (\_->(quitDialog>>= (return . not ))) onDestroy win mainQuit vb <- vBoxNew True 5 hb <- hBoxNew True 5 btn <- buttonNewFromStock stockExecute btn2 <- buttonNewFromStock stockQuit tv <- textViewNew tb <- textBufferNew Nothing textBufferSetText tb "0" textViewSetEditable tv False textViewSetCursorVisible tv False textViewSetBuffer tv tb boxPackStartDefaults vb tv boxPackStartDefaults vb hb boxPackStartDefaults hb btn boxPackStartDefaults hb btn2 hgf <- onClicked btn $ do si <- textBufferGetStartIter tb ei <- textBufferGetEndIter tb val <- textBufferGetText tb si ei False textBufferSetText tb $ show $ (+1) $ read val disconnect hgf onClicked btn2 $ do quit <- quitDialog if quit then widgetDestroy win else return () containerAdd win vb widgetShowAll win mainGUI
