Question

Why Java jFrame setResizable() is failling to act?

Answer 1

+2 A:

You have a mistake in your code; my simple self-contained test program shows that setResizable(false) works just fine:

package com.businesslink.core.tst.ld.dct;

import java.awt.*;
import javax.swing.*;

public class SwgTestFrame1b
extends JFrame
{

public SwgTestFrame1b() {
    super("SwgTestFrame1b");

    setBackground(Color.white);
    setResizable(false);
    pack();
    }

static public void main(String[] args) {
    new SwgTestFrame1b().show();
    }
}

A quick search of your code reveals nowhere that show or setVisible is invoked on mainFrame; it looks like you are only showing dialogs related to mainFrame. Now setResizable is only done on mainFrame, that will not impact any dialogs that are children of mainFrame. Nor will it affect the frame used by your FrameView.

PS, and just FTR, I absolutely abhor windows that are not resizable they are the mark of either an inadequate GUI toolkit or a lazy programmer.

Answer 2

+1 A:

The default application was not contained in a jFrame! It was in jPanel only which I didn't know how to make it none re-sizable. so I added a jFrame

you shouldn't be creating an extra JFrame, your panel was already in a frame You should have used something like this instead of creating a new frame:

getFrame().setResizeable(false);
