Introduction

The AngleSlider is just a widget designed to pick angles.

Usage

Currently this widget is very very simple, and not customizable. For example, its size is fixed because the "wheel" is an image.

You can just :

• select a value with the method setSelection(int value)
• get the selection with the method getSelection, which returns the angle in degrees between 0 and 360.
• Add a selection listener, fired when the selection changed.

Example

A snippet called AngleSliderSnippet is available in the directory src/test/java/org/mihalis/opal/angles.

This example is also available here : https://github.com/lcaron/opal/blob/master/src/test/java/org/mihalis/opal/angles/AngleSliderSnippet.java

Future enhancements

Future enhancements are planned :

• Vectorial drawing, so the size of the widget will be dynamic
• Orientation : currently the value "0" is located in the bottom of the circle, it should be anywere
• Add a reference mark for 0 degree or common angles (45°, 90°...)
