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 #

Arguments

:: Adjustment	`adjustment` - the `Adjustment` which sets the range of the scale.
-> IO VScale

Creates a new VScale.

vScaleNewWithRange #

Arguments

:: 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 scaleSetDigits to correct it.
