[Help] setSize work wrong ???

[dawp]

I'm trying to make a tiny application : click into a button and JFrame will resize

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) 
{
     setSize(500,[COLOR="DarkRed"]1000[/COLOR] ); /// apply for Frame
     System.out.println("width" + getWidth());
     System.out.println("height " + getHeight());
     
}

The result is : width 500 height 920 :confused: .
I cannot understand why i setHeight 1000 but result is 920 . Anybody can help me ???

I usually use setPreferredSize(new Dimension(x, y)) and I usually call it on something other than the JFrame such as the JFrame's contentPane. I then call pack() on the JFrame to get it to listen to my new preferred size.

I tried

setPreferredSize(new Dimension(500, 1000));
pack();

But result didn't change : height 920 :(

It looks as if you called preferred size on the jframe, not its content pane. Truthfully, it's hard to tell what you're doing without seeing a small compilable program that demonstrates your problem, a minimal working example or SSCCE. I suggest you consider creating this and posting this.

Here is it . It was creat by NeatBean IDE

import java.awt.Dimension;

public class MainFrame extends javax.swing.JFrame {

    public MainFrame() {
        initComponents();
    }

    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {

        jButton1 = new javax.swing.JButton();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        addWindowListener(new java.awt.event.WindowAdapter() {
            public void windowClosed(java.awt.event.WindowEvent evt) {
                formWindowClosed(evt);
            }
        });

        jButton1.setText("New");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(129, 129, 129)
                .addComponent(jButton1, javax.swing.GroupLayout.PREFERRED_SIZE, 123, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addContainerGap(148, Short.MAX_VALUE))
        );
        layout.setVerticalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(118, 118, 118)
                .addComponent(jButton1, javax.swing.GroupLayout.PREFERRED_SIZE, 77, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addContainerGap(105, Short.MAX_VALUE))
        );

        pack();
    }// </editor-fold>                        

   [COLOR="Olive"] private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
            /* 
            setSize(500,1000);
            System.out.println(getHeight()); */

            setPreferredSize(new Dimension(500, 1000));
            pack();
            System.out.println(getHeight());

    }   [/COLOR]                                     

    
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new MainFrame().setVisible(true);
            }
        });
    }
SecondFrame a;
    // Variables declaration - do not modify                     
    private javax.swing.JButton jButton1;
    // End of variables declaration                   

}

So strange bc when i set Height small it work perfect , but when it large (out of screen ) it work wrong :(

[camickr]

but when it large (out of screen ) it work wrong

Well, maybe that is a clue, it doesn't make sense to make the frame larger than the screen.

My screen resolution is 1024 x 768 and the size seems to max out a 1036 x 780, so it seems to allow 12 extra pixels. I don't know what the significance of that is.

Maybe that's correct clue. Thanks Fubarable & camickr

You can go with setBounds method
