Overlay a JButton over JLabel in Java Swing?

问题

Is it possible to overlay a Button over a Label in Swing?

For example, if have a JLabel with image and no text, and i want to overlay my button over this JLabel. Label is defined something like:

myLabel = new javax.swing.JLabel(new ImageIcon( myPicture ));

If not, then any ideas how can i realize this, thank you.

EDIT: Actually i read about adding JPanel to a JLabel, when i add a Panel with button layout, it compiles fine but nothing is visible, just the JLabel with image

UPDATE: As suggested by @paranoid-android, somehow i have solved my problem. However i still have to know how can i customize the positions of components overlayed on top of JLabel as i don't have much control (probably because normally i use netbeans for drawing layouts, and this would require hard coding).

Something Like this worked:

ImagePanel(Image image, int id) {
    this.image = image;
    this.tile = false;

    JButton backButton = new JButton();
    JButton nextButton = new JButton();
    backButton.setText(" BACK ");
    nextButton.setText(" NEXT ");


    add(backButton);
    add(nextButton);

};

@Override
public void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(image, 0, 0, getWidth(), getHeight(), this);
}

回答1:

You can do it using a JLayeredPane, although if I understand correctly, the absolute best way to do that would be to override paintComponent:

// as part of your JPanel
@Override
public void paintComponent(Graphics g){
     super.paintComponent(g);
     g.drawImage(background, 0, 0, this);
}

Then you can add components to the panel as you like, without the need for the JLabel.

You can overlap the button and the label, but you would have to do this with a Fixed Layout. You might be able to pull if off with a gridBagLayout, but I doubt it.

Here is more on what you will need.
