Look at Graphics2D.hit() You can build a small Rectangle centered at the mouse click and see if it intersects a Shape.
Will this work for you? -----Original Message----- From: Discussion list for Java 2D API [mailto:[EMAIL PROTECTED] On Behalf Of Danilo Costa Sent: Thursday, August 26, 2004 8:55 AM To: [EMAIL PROTECTED] Subject: [JAVA2D] Click detection Hi EveryBody! I'm trying to do the following: I have some geometrics objects such as ellipses, rectanglesand poly-lines instancied and drawn on a canvas, and I need to know when the user clicks over the lines of one of its. There is the method called "contains(double x, double y)" but it checks if the point is inside of some geom object .. I need something like the Line2D method : " int relativeCCW(double PX, double PY)" that return 0 when the point lies exactly on the line segment. But I need to know when it lies on a ellipse , on the lines of a rectangle, or polyline, or polygon! I hope I was clear Please, I realy need help on it!
