Changing window state by JFrame

Question

Hi guys,
I want to maximize a JFrame window, bit I dont know how.
I tried it with
public void maximizeWindow() {
frame.setExtendedState(Frame.MAXIMIZED_BOTH); // frame is the instance of JFrame
}I too tried it with Frame.MAXIMIZED_VERT and Frame.MAXIMIZED_HORIZ, bit it didn't work.
About a quick help I would be very happy.

Answer 1

package fi.stuff.testing;
import javax.swing.JFrame;
import java.awt.Frame;
public class Test
     public static void main(String[] args)
          JFrame frame = new JFrame("Maximized");
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setExtendedState(Frame.MAXIMIZED_BOTH);
          frame.setVisible(true);
}It does work here. Have you perhaps set setResizable(false)?
Cheers
