ScaleButton, VolumeButton

Required Methods§

Gets the Adjustment associated with the ScaleButton’s scale.

See RangeExt::adjustment() for details.

Returns

the adjustment associated with the scale

Retrieves the minus button of the ScaleButton.

Returns

the minus button of the ScaleButton

Retrieves the plus button of the ScaleButton

Returns

the plus button of the ScaleButton

Retrieves the popup of the ScaleButton.

Returns

the popup of the ScaleButton

Gets the current value of the scale button.

Returns

current value of the scale button

Sets the Adjustment to be used as a model for the ScaleButton’s scale.

adjustment

a Adjustment

Sets the icons to be used by the scale button.

icons

a None-terminated array of icon names

Sets the current value of the scale.

If the value is outside the minimum or maximum range values, it will be clamped to fit inside them.

The scale button emits the signal::ScaleButton::value-changed signal if the value changes.

value

new value of the scale button

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.

Emitted to dismiss the popup.

This is a keybinding signal.

The default binding for this signal is Escape.

Emitted to popup the scale widget.

This is a keybinding signal.

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

Emitted when the value field has changed.

value
