GI.Gtk.Objects.ScaleButton

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.

The popup widget that contains the scale has a .scale-popup style class.

Properties

adjustment

No description available in the introspection data.

constructScaleButtonAdjustment :: (IsScaleButton o, MonadIO m, IsAdjustment a) => a -> m (GValueConstruct o)

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

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 ()

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, MonadIO m) => [Text] -> m (GValueConstruct o)

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])

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 ()

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

set scaleButton [ #icons := value ]

size

No description available in the introspection data.

constructScaleButtonSize :: (IsScaleButton o, MonadIO m) => IconSize -> m (GValueConstruct o)

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

getScaleButtonSize :: (MonadIO m, IsScaleButton o) => o -> m IconSize

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

get scaleButton #size

setScaleButtonSize :: (MonadIO m, IsScaleButton o) => o -> IconSize -> m ()

Signals

popdown

type ScaleButtonPopdownCallback = IO ()

The popdown signal is a [keybinding signal][GtkBindingSignal] which gets emitted to popdown the scale widget.

The default binding for this signal is Escape.

Since: 2.12

afterScaleButtonPopdown :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonPopdownCallback) -> m SignalHandlerId

Connect a signal handler for the popdown signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after scaleButton #popdown callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onScaleButtonPopdown :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonPopdownCallback) -> m SignalHandlerId

Connect a signal handler for the popdown signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on scaleButton #popdown callback

popup

type ScaleButtonPopupCallback = IO ()

The popup signal is a [keybinding signal][GtkBindingSignal] which gets emitted to popup the scale widget.

The default bindings for this signal are Space, Enter and Return.

Since: 2.12

afterScaleButtonPopup :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonPopupCallback) -> m SignalHandlerId

Connect a signal handler for the popup signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after scaleButton #popup callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onScaleButtonPopup :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonPopupCallback) -> m SignalHandlerId

Connect a signal handler for the popup signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on scaleButton #popup callback

valueChanged

type ScaleButtonValueChangedCallback

Arguments

 = Double

value: the new value

-> IO ()

The valueChanged signal is emitted when the value field has changed.

Since: 2.12

afterScaleButtonValueChanged :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonValueChangedCallback) -> m SignalHandlerId

Connect a signal handler for the valueChanged signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after scaleButton #valueChanged callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onScaleButtonValueChanged :: (IsScaleButton a, MonadIO m) => a -> ((?self :: a) => ScaleButtonValueChangedCallback) -> m SignalHandlerId

Connect a signal handler for the valueChanged signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on scaleButton #valueChanged callback
