SelectionToolSample

public class SelectionToolSample
extends java.lang.Object

SelectionToolSample demonstrates how the SelectionTool works.

Internally, the SelectionTool uses three smaller tools (named as 'Tracker') to fulfill its task. If the user presses the mouse button over an empty area of a drawing, the SelectAreaTracker comes into action. If the user presses the mouse button over a figure, the DragTracker comes into action. If the user presses the mouse button over a handle, the HandleTracker comes into action.

You need to edit the source code as marked below.
