Method Detail

handleNewStroke

public void handleNewStroke(NewStrokeEvent evt)

This callback is called when the stroke should be handled by this object. If you, the listener, have consumed the Stroke, then call SatinEvent.setConsumed() with true to signify that it is consumed and no one else should handle it. Furthermore, if you don't want the stroke to be rendered, then call SatinEvent.setShouldRender(boolean) with false. By default, the stroke will be rendered.

Parameters:

evt - is the event to handle.

handleUpdateStroke

public void handleUpdateStroke(UpdateStrokeEvent evt)
