Thread: [wxhaskell-users] How do I call statusBarSetStatusWidths :: StatusBar a -> Int -> Ptr CInt -> IO ()

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi.  I'd like to call statusBarSetStatusWidths - apparently it wants an =
array of integers (the status field widths) - how do I create that as a =
Ptr CInt?

Thanks!  -- Dave

Hi Dave,

This should be in wxhaskell of course, I'll add it to the next version.
For now, you can use the same code as in "WXCore.Frame.statusBarCreateFields".
If you don't have access to the sources, here it is:

  import Foreign.Marshal.Array
  ...
  statusBarCreateFields :: Frame a -> [Int] -> IO (StatusBar ())
  statusBarCreateFields parent widths
    = do ...
          then do withArray (map toCInt widths)
                            (\pwidths -> statusBarSetStatusWidths sb (length widths) pwidths)
                  ...

All the best,
  Daan.

btw. I am curious why you need to call this function? Are the functions
in "WX.Menu" not good enough (and why not)? Maybe we can improve the interface?

Because I didn't know about it!  I was looking in Controls for a status bar
wrapper, not Menus.  None of the samples had status bars and I wanted to
start off by doing something that wasn't in the samples.  I guess I need to
browse *all* of the documentation so I have a better idea of what's where.

Thanks for your help!  -- David

You've hit one the most important issues wxHaskell: documentation :-)
Although I think that it is a good thing that there is at least
some (good) documentation, it would be good if there was some better
overview of where to find the things you are looking for -- especially
with regard to attributes.

Success with the statusbars,
  -- Daan.

ps. See the "samples/wx/" "minimal" and "imageviewer" example for a statusbar
