public class Scale extends Range
A slider control which allows the user to manipulate a numeric value.
As with many other Widget hierarchies in
GTK, there is a horizontal (HScale) and vertical (VScale) implementation for you to choose from.
The default
position for the value to be displayed is TOPwhich may not be quite what you want. UsesetValuePosition()to change it.Otherwise, most of the useful methods (notably those relating to the value) are inherited from the parent class,
Range.- Since:
- 4.0.6
