[wxhaskell-users] dynamically setting slider bounds?

[Conal E. <co...@co...>]

Is it possible to change the min & max values of a slider after creation?

Maybe

    import Graphics.UI.WXCore

    sliderSetRange :: Slider a -> Int -> Int -> IO ()

works.
Sometimes it is necessary to turn to WXCore functions because not  
everything is available in the higher-level WX layer. The two *huge*  
HTML pages come in handy then:

http://wxhaskell.sourceforge.net/doc/ 
Graphics.UI.WXCore.WxcClassesAL.html
http://wxhaskell.sourceforge.net/doc/ 
Graphics.UI.WXCore.WxcClassesMZ.html

Good luck, Arjan

sliderSetRange does change the bounds, but the screen space reserved for
each bounds of the slider widget does not get increased, so when the bound
gains another digit, the last digit is invisible until i manually resize th=
e
window.  i'm using this layout for each widget::

    boxed label $ hfill $ widget ctl

and this for putting the layouts together:

    set f [ layout :=3D container p $ column 5 $ layouts ]

i thought maybe "dynamic" layout would get the bounds space re-adjusted.
when i apply it after "boxed label", i see no effect.  when i apply it afte=
r
widget or after hfill, i don't get nearly enough width to see the widgets
and much more height than i want.  i also tried combinations of "dynamic" i=
n
the widget layout *and* the frame layout, with no success.

any ideas?  is this a bug in "dynamic"?

Cheers,  - Conal

Does refit help?
---
refit :: Window a -> IO ()
Ensure that a widget is refitted inside a window when its size changes, 
for example when the text of a staticText control changes. (calls 
windowReFit)
---

Otherwise, can you send me some code I can compile so that I can 
reproduce the problem?
