What does # mean in this code ? (from Data.List)

findIndices p ls = loop 0# ls
 where
   loop _ [] = []
   loop n (x:xs) | p x   = I# n : loop (n +# 1#) xs
  | otherwise = loop (n +# 1#) xs

[Haskell-cafe] qtHaskell signal and slots

[c8h10n4o2]

I have the following code that tries to resize window after a click. But
nothing happens. If I use a builtin slot that does not need a function, such
as close, quit it works, however for any other slot it seems my function
is ignored. Which slot/signal should I use and how?

module Main where

import Qtc.Classes.Qccs
import Qtc.Classes.Gui
import Qtc.Gui.Base
import Qtc.Gui.QApplication
import Qtc.Gui.QPushButton
import Qtc.Core.QFile
import Qtc.Tools.QUiLoader
import Qtc.Enums.Core.QIODevice
import Qtc.Core.Base
import Qtc.ClassTypes.Gui
import Qtc.Gui.QAbstractButton

main = do 
 app - qApplication  ()
 loader - qUiLoader ()
 uiFile - qFile slide.ui
 open uiFile fReadOnly
 ui - load loader uiFile
 close uiFile ()
 add - findChild ui (QPushButton*, pushButton) 
 connectSlot add clicked() add click()  $ t ui
 qshow ui ()
 qApplicationExec ()
 
t :: QWidget () - QWidget () - IO ()
t ui _= resize ui (500::Int ,500::Int)

[Haskell-cafe] GUI Designer

[c8h10n4o2]

There's a tutorial on how to use qtDesigner with qtHaskell ? Or how to use
XRC files with wxHaskell?

I was able to parse function definition, but function call still is a
problem,

And why 
b - between (char ',') (char '=') (sepBy alphaNum (char ',') )
does not return [String] ?

I read the parsec documentation and saw my mistake.
By the way, there is a parser that returns [String] for my case?

No, it is not secret. I'm having trouble to define functions. Take a look at
my code(please be gentle)

[c8h10n4o2]

The problem is there. A function in Hai would be function-name,
arg1,argn=body.
Func stores function name,arguments and body as Strings(I was thinking to
put Func String String String).
The parser func that I wrote so far try to parse a function definition, not
a function call.
But when I try to store the function on my Map I get a error with somthing
called 'functional dependencies'(which I don't know what is).
