Description
A vertical slider widget for selecting a value from a range
- data VScale
- class ScaleClass o => VScaleClass o
- castToVScale :: GObjectClass obj => obj -> VScale
- gTypeVScale :: GType
- toVScale :: VScaleClass o => o -> VScale
- vScaleNew :: Adjustment -> IO VScale
- vScaleNewWithRange :: Double -> Double -> Double -> IO VScale
Detail
The VScale
widget is used to allow the user to select a value using a
vertical slider. To create one, use vScaleNewWithRange
.
The position to show the current value, and the number of decimal places
shown can be set using the parent Scale
class's functions.

Constructors
Arguments
:: Adjustment |
|
-> IO VScale |
Creates a new VScale
.
Arguments
:: Double |
|
-> Double |
|
-> Double |
|
-> IO VScale |
Creates a new vertical scale widget that lets the user input a number
between min
and max
(including min
and max
) with the increment
step
. step
must be nonzero; it's the distance the slider moves when
using the arrow keys to adjust the scale value.
Note that the way in which the precision is derived works best if step
is a power of ten. If the resulting precision is not suitable for your
needs, use Graphics.UI.Gtk.Abstract.Scale.scaleSetDigits
to correct it.
