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

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 hScaleNewWithRange.

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. Must be nonzero.
-> 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.
