This program behaves like the line tool common in drawing programs.

import objectdraw.*;

public class MysteryProgram extends WindowController {
	private Line currentLine;
	private Location start;
	
	public void onMousePress( Location point )
	{
		start = point;
		currentLine = new Line( point, point, canvas);
	}

	public void onMouseDrag( Location point )
	{
	    // Erase current line
	    currentLine.removeFromCanvas();
		
	    currentLine = new Line( start, point, canvas);
	}
}
