Description

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.

GtkVScale has been deprecated, use Scale instead.

Synopsis

newtype VScale = VScale (ManagedPtr VScale)
class GObject o => IsVScale o
toVScale :: (MonadIO m, IsVScale o) => o -> m VScale
noVScale :: Maybe VScale
vScaleNew :: (HasCallStack, MonadIO m, IsAdjustment a) => a -> m VScale
vScaleNewWithRange :: (HasCallStack, MonadIO m) => Double -> Double -> Double -> m VScale

class GObject o => IsVScale o Source #

Type class for types which can be safely cast to VScale, for instance with toVScale.

toVScale :: (MonadIO m, IsVScale o) => o -> m VScale Source #

Cast to VScale, for types for which this is known to be safe. For general casts, use castTo.

noVScale :: Maybe VScale Source #

A convenience alias for Nothing :: Maybe VScale.

Methods

new

vScaleNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsAdjustment a)
=> a	`adjustment`: the `Adjustment` which sets the range of the scale.
-> m VScale	Returns: a new `VScale`.

Deprecated: (Since version 3.2)Use scaleNew with OrientationVertical instead

Creates a new VScale.

newWithRange

vScaleNewWithRange Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Double	`min`: minimum value
-> Double	`max`: maximum value
-> Double	`step`: step increment (tick size) used with keyboard shortcuts
-> m VScale	Returns: a new `VScale`

Deprecated: (Since version 3.2)Use scaleNewWithRange with OrientationVertical instead

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.
