Thread: How to maximize a JFrame Form?

To maximize a JFrame you need the following code.

myFrame.setExtendedState(JFrame.MAXIMIZED_BOTH);

And to put an image in a JPanel you would create a JLabel and set the ImageIcon for that JLabel.

someLabel.setIcon(new ImageIcon("C:\\Documents and Settings\\User\\Desktop\\image.png"));

Thanks buddy... I think that shall work cheers...
The Maximizing worked..

but the code to place an image ain't working

Basically I am using a JDesktopPane to place internal frames in my Application and i want to apply Image to this JDesktopPane as a background.
Now what happens is when i use a label inside this DesktopPane to place an image as :

public class User extends javax.swing.JFrame 
{
    public User() 
    {
        this.setExtendedState(JFrame.MAXIMIZED_BOTH);
        image.setIcon(new ImageIcon("D:\\Visuals\\walls\\Windows-8-Grass-Wallpaper1.jpg"));
        initComponents();
        paneltransact.setVisible(false);
        panelmastershoots.setVisible(false);
        panelmasterview.setVisible(false);
        //int height,width;
    }

where during runtime the following error is generated:

error3.jpg

please help i also tried placing a panel inside the desktop pane and then placing a label inside the panel and then working out and same error showed up.

Where did you initialize the JLabel? It seems like you might be missing the following.

JLabel image = new JLabel();
// And then then set the imageicon
image.setIcon(new ImageIcon("D:\\Visuals\\walls\\Windows-8-Grass-Wallpaper1.jpg"));
