The Range Slider is a control that lets you input two values, typically an upper and a lower bound. Normal sliders just lets you input one value.
Because the look and feel is very close to the
Scale widget, I've decided to copy the same methods.
The only difference concerns the "selection" getters and setters, because there are 2 values.
An example called RangeSliderSnippet.java is located in the plugin org.eclipse.nebula.widgets.opal.rangeslider.snippets.
This example is also available here : https://git.eclipse.org/c/nebula/org.eclipse.nebula.git/tree/widgets/opal/rangeslider/org.eclipse.nebula.widgets.opal.rangeslider.snippets/src/org/eclipse/nebula/widgets/opal/rangeslider/snippets/RangeSliderSnippet.java
