I wanted to have a vertical slider with small numbers at the bottom and
large numbers at the top. To this end I implemented a variant of
'vslider' that automatically inverses its direction, if the bottom value
is smaller than the top value. You may like to replace the current
'vslider' implementation by this one (and the hslider accordingly).
wxSL_INVERSE :: Int
wxSL_INVERSE = 0x1000
vslider ::
WX.Window a -> Bool -> Int -> Int ->
[WX.Prop (WX.Slider ())] -> IO (WX.Slider ())
vslider parentW showLabels top bottom props =
let (minV, maxV, dirFlags) =
if top<bottom
then (top, bottom, 0)
else (bottom, top, wxSL_INVERSE)
in WX.sliderEx parentW minV maxV
(WXCore.wxVERTICAL .+. dirFlags -- .+. wxSL_LEFT .+.
wxSL_AUTOTICKS
.+. (if showLabels then WXCore.wxSL_LABELS else 0))
props
