public class RJThumbWheel extends JComponent
This class has the behavior of a slider, without boundaries (so you can set values beyond the visible min and max). Furthermore, it has a 3D thumbwheel look, that is particularly nice for radial values. It also has an optional linear look, which is good for unbounded linear values.

      public boolean getValueIsAdjusting()
      Returns whether the thumbweel is in a state of rapid interactive use (from mouse loop).

    • processMouseEvent

      protected void processMouseEvent(MouseEvent e)
      Forwards mouse events to mouse methods.
      Overrides:
      processMouseEvent in class JComponent

    • processMouseMotionEvent

      protected void processMouseMotionEvent(MouseEvent e)
      Forwards mouse events to mouse methods.

    • getValueAtPoint

      public double getValueAtPoint(Point aPoint)
      This method gives the value that corresponds to a point with respect to the given frame and the visible range. When in radial mode, the point on the thumbwheel is approximated with a power series for arcCos to get legal values for points outside of the frame.
