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 "value-changed" signal if the value changes.

Since 2.12

gtk_scale_button_get_adjustment ()

GtkAdjustment *     gtk_scale_button_get_adjustment     (GtkScaleButton *button);

Gets the GtkAdjustment associated with the GtkScaleButton's scale. See gtk_range_get_adjustment() for details.

Retrieves the minus button of the GtkScaleButton.

Since 2.14

The "adjustment" property

  "adjustment"               GtkAdjustment*        : Read / Write

The GtkAdjustment that contains the current value of this scale button object.

The "icons" property

  "icons"                    GStrv                 : Read / Write

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 GtkScaleButton reflects the current value of the scale better for the users.

Since 2.12

The "size" property

  "size"                     GtkIconSize           : Read / Write
