Detecting Dynamic Resizing of a window in real time

[chris_moulton22]

Is there some kind of a window listener with a method that can return the size of a jframe constantly during runtime so if a resize happens you can manipulate other things in the program accordingly. I have a simple program with circles bouncing around and i want to make it so if i resize the jframe (while viewing it with jcreators applet viewer) that i can resize the boundaries of where the circles can bounce to. - Sorry if thats confusing.

Thanks -

yes there is. you will have to add a componentlistener to your frame:

frame.addComponentListener(
	new ComponentListener(){
		public void componentResized(ComponentEvent e){
			System.out.println("*FRAME: component resized");
			Dimension size = frame.getSize();
			doSomething();
		}
				
		public void componentMoved(ComponentEvent e) {
			System.out.println("*FRAME: component moved");
			Point location = frame.getLocation();
		}

		public void componentHidden(ComponentEvent e) {}
		public void componentShown(ComponentEvent e) {}
	}
);

this will enable you to trace: resizing, moving, hiding and showing of your frame.
