Detail
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.

Constructors
Arguments
| :: IconSize |
|
| -> Double |
|
| -> Double |
|
| -> Double |
|
| -> [String] | icons |
| -> IO ScaleButton |
Creates a ScaleButton, with a range between min and max, with a
stepping of step.
Methods
Arguments
| :: ScaleButtonClass self | |
| => self | |
| -> [String] | icons |
| -> IO () |
Sets the icons to be used by the scale button. For details, see the icons property.
Arguments
| :: ScaleButtonClass self | |
| => self | |
| -> IO Widget | returns the popup of the |
Retrieves the popup of the ScaleButton.
- Available since Gtk+ version 2.14
scaleButtonGetPlusButtonSource
Arguments
| :: ScaleButtonClass self | |
| => self | |
| -> IO Widget | returns the plus button of the |
Retrieves the plus button of the ScaleButton.
- Available since Gtk+ version 2.14
scaleButtonGetMinusButtonSource
Arguments
| :: ScaleButtonClass self | |
| => self | |
| -> IO Widget | returns the minus button of the |
Retrieves the minus button of the ScaleButton.
- Available since Gtk+ version 2.14
Attributes
scaleButtonValue :: ScaleButtonClass self => Attr self DoubleSource
The value of the scale.
Default value: 0
scaleButtonSize :: ScaleButtonClass self => Attr self IconSizeSource
The icon size.
Default value: ''IconSizeSmallToolbar''
scaleButtonAdjustment :: ScaleButtonClass self => Attr self AdjustmentSource
The Adjustment that contains the current value of this scale button object.
scaleButtonIcons :: ScaleButtonClass self => ReadWriteAttr self [String] (Maybe [String])Source
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
Signals
scaleButtonPopdown :: ScaleButtonClass self => Signal self (IO ())Source
The popdown signal is a keybinding signal which gets emitted to popdown the scale widget.
The default binding for this signal is Escape.
scaleButtonPopup :: ScaleButtonClass self => Signal self (IO ())Source
The popup signal is a keybinding signal which gets emitted to popup the scale widget.
The default bindings for this signal are Space, Enter and Return.
scaleButtonValueChanged :: ScaleButtonClass self => Signal self (Double -> IO ())Source
The scaleButtonValueChanged signal is emitted when the value field has changed.
