java - How to get a dot(or a very small circle) to center at the middle of a JFrame? -
i trying dot stay @ center of screen regardless of user move screen around, or resize screen using paint graphics or graphics2d.
thanks in advance
public void paint(graphics g) { super.paint(g); int x = getwidth() /2 ; int y = getheight() / 2; g.drawoval(x, y, 10, 10); }
to make sure stays in middle time, add componentlistener jframe, this:
myjframe() { addcomponentlistener(new componentadapter() { @override public void componentresized(componentevent e) { repaint(); } }); }
the componentlistener not needed....
