how can i put a JButton on an image?
I am trying to fix a JFrame where there will be a background image and on the image JButtons which will do some commands. I try to do it without layout because i want to put small buttons in some specific locations on the JFrame but every time i do it, the background image comes to the front or the JFrame has size equal to the JFrame size. With the following code, the JButton has the same size to JFrame. I have tried to change the size and location of the JButton but nothing. Can you help me please?
here is the code
public final class Test extends JCo开发者_运维问答mponent
{
private Image background;
private JFrame frame;
private Dimension dimension;
public Test()
{
dimension = new Dimension(15, 15);
frame = new JFrame("Iphone");
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(this);
frame.setBounds(641, 0, 344, 655);
frame.setVisible(true);
test = displayButton("tigka");
frame.getContentPane().add(test);
}
public void update(Graphics g)
{
paint(g);
}
public void paintComponent(Graphics g)
{
super.paintComponents(g);
g.drawImage(background, 0, 25, null); // draw background
// label();
test = displayButton("test");
}
public JButton displayButton(String name)
{
JButton button = new JButton(name);
button.setSize(100, 100);
button.setPreferredSize(dimension);
return button;
}
You need to change the content pane to get a background for your Frame.
public static void main(String[] args) throws IOException {
JFrame frame = new JFrame("Test");
frame.setContentPane(new JPanel() {
BufferedImage image = ImageIO.read(new URL("http://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png"));
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 0, 0, 300, 300, this);
}
});
frame.add(new JButton("Test Button"));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 300);
frame.setVisible(true);
}
Output:
Have you tried using a JLabel with HTML in the label? Something like this:
import javax.swing.*;
public class SwingImage1
{
public static void main( String args[] )
{
JFrame frm = new JFrame( "Swing Image 1" );
JLabel lbl = new JLabel( "<html><body><img src=\"http://liv.liviutudor.com/images/liv.gif\"></body></html>" );
frm.getContentPane().add( lbl );
frm.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frm.pack();
frm.setVisible( true );
}
}
then on top of your label you can add your button?
You should swap those two lines:
super.paintComponents(g); //paints the children, like the button
g.drawImage(background, 0, 25, null); // draw background later possibly overwriting the button
Thus it should be this order:
g.drawImage(background, 0, 25, null);
super.paintComponents(g);
Additionally, note that the content pane's default layout is BorderLayout. Thus you'd set the layout of your content pane to null explicitly.
/*it is simple to put button on image first set image by making object then make button object & add the button object direct to image object rather then add to frame.*/
package frame;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class frame
{
public frame()
{
JFrame obj = new JFrame("Banking Software");
JButton b1 = new JButton("Opening Account");
JLabel image = new JLabel(new ImageIcon("money.jpg"));
image.setBounds(0,0, 1600, 1400);
obj.setExtendedState(JFrame.MAXIMIZED_BOTH);
obj.add(image);
b1.setBounds(500,400, 100, 40);
image.add(b1);
obj.setVisible(true);
}
public static void main(String args[])
{
new frame();
}
}
加载中,请稍侯......
