Setting minimum size limit for a window in java swing

Question

I have a JFrame which has 3 JPanels in GridBagLayout..

Now, when I minimize a windows, after a certain limit, the third JPanel tends to disappear. I tried setting minimizing size of JFrame using setMinimumSize(new Dimension(int,int)) but no success. The windows can still be minimized.

So, I actually want to make a threshhold, that my window cannot be minimized after a certain limit.

How can I do so?

Code:-

import java.awt.Dimension;

import javax.swing.JFrame;

public class JFrameExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Hello World");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setMinimumSize(new Dimension(400, 400));
        frame.setVisible(true);
    }
}

Also:

Gives me output like

**UPDATE: ** The same when run though Netbeans IDE gives expected output.. When I run through "java JFrameExample" compiler, I am facing issues.. Now, what that means??

Answer 1

The documentation tells me, that this behavior is platform dependent. Especially, since the following example code works for me as desired in Windows Vista:

import java.awt.Dimension;

import javax.swing.JFrame;

public class JFrameExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Hello World");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setMinimumSize(new Dimension(100, 100));
        frame.setVisible(true);
    }
}
