Image Not Draw in GUI wehen Starting
This first step of GUI i design for a Java Application.
But my loading image ( hard code to the url) will not display in when GUI starts.
After display the blank frame I have to manually bit resize(using mouse) the frame to see the image.
_
import java.awt.BorderLayout;
import java.net.URL;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Example extends javax.swing.JPanel {
private JFrame frame ;
java.net.URL url;
ImageIcon icon;
JPanel buttonPanel;
JButton but1;
String curDir;
public Example(){
super();
frame = new JFrame();
frame.setSize(500,500);
frame.setVisible(true);
buttonPanel = new javax.swing.JPanel();
frame.getContentPane().add(this,BorderLayout.CENTER);
url = getClass().getResource("/feature.jpg");
buttonPanel.add(but1);
frame.addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
frame.repaint();
}
});
java.awt.Dimension dim = getToolkit().getScreenSize();
frame.setLocation((int)dim.getWidth()/2 - 100, (int)dim.getHeight()/2 - 100);
frame.getContentPane().add(buttonPanel,BorderLayout.SOUTH);
frame.setSize(500,500);
frame.repaint();
}
public void paint(java.awt.Graphics g) {
if(url!=null)
{
icon = new javax.swing.ImageIcon(url);
java.awt.Image image = icon.getImage();
g.drawImage(image, 2, 20, image.getWidth(this), image.getHeight(this), this);
frame.repaint();
}
}
private void exitForm(java.awt.event.WindowEvent evt) {
System.exit(0);
}
public static void main(String d[]){
new Example();
}
}
