Description
A vertical slider widget for selecting a value from a range
Synopsis
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
vScaleNew
:: Adjustment | `adjustment` - the `Adjustment` which sets the range of the scale.
-> IO VScale |
Creates a new `VScale`.
vScaleNewWithRange
:: Double | `min` - minimum value
-> Double | `max` - maximum value
-> Double | `step` - step increment (tick size) used with keyboard shortcuts
-> 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.
