GI.Gtk.Objects.VScale

Contents

Description

The tVScale 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 tScale class’s functions.

GtkVScale has been deprecated, use tScale instead.

class (GObject o, IsDescendantOf VScale 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

Overloaded methods

new

vScaleNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsAdjustment a) 
=> a

adjustment: the tAdjustment which sets the range of the scale.

-> m VScale

Returns: a new tVScale.

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

Creates a new tVScale.

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 tVScale

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.
