Dear friends.
I google quite a while, also search this excellent forum, I need to edit JLabel's Text String at run time, like just right click or left click mouse, then I can edit/update JLabel's Text String, then persist my updating forever untill next I change them.
Any guru can throw some light or gave some good example?
Thanks
Sunny
Thanks, still confused,
My Jable JL has two parts:
Upper part: Icon
Lower Part: TextString
so I need to put TextField in lower part so that I can edit at my will,
see code below
import javax.swing.*;
import java.awt.*;
public class JTextFieldTest extends JFrame {
public JTextFieldTest() {
super("JTextField Test");
getContentPane().setLayout(new FlowLayout());
JLabel jl = new JLabel();
jl.setPreferredSize(new Dimension(300, 200));
JTextField textField1 = new JTextField("1", 1);
JTextField textField2 = new JTextField("22", 2);
JTextField textField3 = new JTextField("333", 3);
jl.setLayout(new FlowLayout());
jl.add(textField1);
jl.add(textField2);
jl.add(textField3);
getContentPane().add(jl);
setSize(300, 200);
setVisible(true);
}
public static void main(String argv[]) {
new JTextFieldTest();
}
}
Is it correct?
But I hope to remove bevel in TextField so that it looks like a pane untill I click it the TextField will appear.
thanks for advice
sunny
Michael: can you advice more details? some code maybe helpful.
see my code below,
import javax.swing.*;
import java.awt.*;
public class JTextFieldTest extends JFrame {
public JTextFieldTest() {
super("JTextField Test");
getContentPane().setLayout(new FlowLayout());
JLabel jl = new JLabel();
jl.setPreferredSize(new Dimension(300, 400));
JTextField textField3 = new JTextField("This is a fat Pig", 3);
ImageIcon pigIcon = createImageIcon("Pig.gif","a cute pig");
jl.setLayout(new BorderLayout());
jl.add(textField3,BorderLayout.SOUTH);
jl.setIcon(pigIcon);
getContentPane().add(jl);
setSize(300, 400);
setVisible(true);
}
/** Returns an ImageIcon, or null if the path was invalid. */
protected static ImageIcon createImageIcon(String path,
String description) {
java.net.URL imgURL = TextSamplerDemoNew.class.getResource(path);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + path);
return null;
}
}
public static void main(String argv[]) {
new JTextFieldTest();
}
}
Here I can put Icon in top and TextField at bottom, but TextField looks not so good, I hope it display like a normal label, not really TextField until I click it.
any idea?
Thanks
sunny
here's something to play around with
import javax.swing.*;
import java.awt.*;
class Testing
{
Image img = null;
public void buildGUI()
{
String imageFile = "test.gif";
try
{
img = javax.imageio.ImageIO.read(new java.net.URL(getClass().getResource(imageFile), imageFile));
}
catch(Exception e){}
JTextField tf = new JTextField(5){
protected void paintComponent(Graphics g) {
super.paintComponent(g);
if(img != null) g.drawImage(img,0,0,this);
}
};
if(img != null) tf.setMargin(new Insets(img.getHeight(tf),0,0,0));
JFrame f = new JFrame();
f.getContentPane().add(tf);
f.pack();
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
}
public static void main(String[] args)
{
SwingUtilities.invokeLater(new Runnable(){
public void run(){
new Testing().buildGUI();
}
});
}
}
