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
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.
