Hi all
I have a jpanel that popup after button clicking on.
So inside my jframe popup i have different jtextfield with some values.
I want that when I select one of the jtextfield (just with the cursor on)
its value fill up parent jframe jtextfield.
Monstly i need to fill up a jtextfiled in a parent jframe of my popup jframe.
Hope to be clear
Regards
hey,
you could use a focuslistener. so.. add a focuslistener to your textfields in the popup and in focusgained() set the textfield text from your "parent"-frame with the text from your popup textfield. A little demo code.....
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.FocusEvent;
import java.awt.event.FocusListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class MyFrame extends JFrame {
private JTextField field = new JTextField("myFrameField");
public static void main(String[] args) {
new MyFrame();
}
public MyFrame() {
JPanel panel = new JPanel();
panel.add(field);
JButton button = new JButton("popup");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
new Popup();
}
});
panel.add(button);
this.setContentPane(panel);
this.setLocation(100, 100);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.pack();
this.setVisible(true);
}
public JTextField getField() {
return field;
}
class Popup extends JFrame implements FocusListener {
public Popup(){
JPanel pane = new JPanel();
final JTextField field = new JTextField("first");
final JTextField field2 = new JTextField("second");
field.addFocusListener(this);
field2.addFocusListener(this);
pane.add(field);
pane.add(field2);
this.setContentPane(pane);
this.setLocation(200, 200);
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
this.pack();
this.setVisible(true);
}
public void focusGained(FocusEvent e) {
getField().setText(((JTextField)e.getComponent()).getText());
}
public void focusLost(FocusEvent e) {}
}
}
hope it helps.... :)
