Description

The HScale widget is used to allow the user to select a value using a horizontal 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.

GtkHScale has been deprecated, use Scale instead.

Synopsis

newtype HScale = HScale (ManagedPtr HScale)
class GObject o => IsHScale o
toHScale :: (MonadIO m, IsHScale o) => o -> m HScale
noHScale :: Maybe HScale
hScaleNew :: (HasCallStack, MonadIO m, IsAdjustment a) => Maybe a -> m HScale
hScaleNewWithRange :: (HasCallStack, MonadIO m) => Double -> Double -> Double -> m HScale

class GObject o => IsHScale o Source #

Type class for types which can be safely cast to HScale, for instance with toHScale.

toHScale :: (MonadIO m, IsHScale o) => o -> m HScale Source #

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

noHScale :: Maybe HScale Source #

A convenience alias for Nothing :: Maybe HScale.

Methods

new

hScaleNew Source #

Arguments

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

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

Creates a new HScale.

newWithRange

hScaleNewWithRange Source #

Arguments

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

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

Creates a new horizontal 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.
