GI.Gtk.Objects.ScaleButton

Contents

Description

ScaleButton provides a button which pops up a scale widget. This kind of widget is commonly used for volume controls in multimedia applications, and GTK+ provides a VolumeButton subclass that is tailored for this use case.

CSS nodes

GtkScaleButton has a single CSS node with name button. To differentiate it from a plain Button, it gets the .scale style class.

Synopsis

Exported types

class GObject o => IsScaleButton o Source #

Type class for types which can be safely cast to ScaleButton, for instance with toScaleButton.

toScaleButton :: (MonadIO m, IsScaleButton o) => o -> m ScaleButton Source #

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

Properties

adjustment

No description available in the introspection data.

constructScaleButtonAdjustment :: (IsScaleButton o, IsAdjustment a) => a -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “adjustment” property. This is rarely needed directly, but it is used by new.

getScaleButtonAdjustment :: (MonadIO m, IsScaleButton o) => o -> m Adjustment Source #

Get the value of the “adjustment” property. When overloading is enabled, this is equivalent to

get scaleButton #adjustment

setScaleButtonAdjustment :: (MonadIO m, IsScaleButton o, IsAdjustment a) => o -> a -> m () Source #

Set the value of the “adjustment” property. When overloading is enabled, this is equivalent to

set scaleButton [ #adjustment := value ]

icons

The names of the icons to be used by the scale button. The first item in the array will be used in the button when the current value is the lowest value, the second item for the highest value. All the subsequent icons will be used for all the other values, spread evenly over the range of values.

If there's only one icon name in the icons array, it will be used for all the values. If only two icon names are in the icons array, the first one will be used for the bottom 50% of the scale, and the second one for the top 50%.

It is recommended to use at least 3 icons so that the ScaleButton reflects the current value of the scale better for the users.

Since: 2.12

constructScaleButtonIcons :: IsScaleButton o => [Text] -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “icons” property. This is rarely needed directly, but it is used by new.

getScaleButtonIcons :: (MonadIO m, IsScaleButton o) => o -> m (Maybe [Text]) Source #

Get the value of the “icons” property. When overloading is enabled, this is equivalent to

get scaleButton #icons

setScaleButtonIcons :: (MonadIO m, IsScaleButton o) => o -> [Text] -> m () Source #

Set the value of the “icons” property. When overloading is enabled, this is equivalent to

set scaleButton [ #icons := value ]

size

Signals

popdown

type C_ScaleButtonPopdownCallback = Ptr () -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type ScaleButtonPopdownCallback = IO () Source #
