Retrieve input entered in a JDialog
- by Jules Olléon
I extended JDialog to create a custom dialog where the user must fill some fields :
How should I retrieve the data entered ?
I came up with a solution that works. It mimics JOptionPane but the way I do it looks ugly to me because of the static fields involved... Here is roughly my code :
public class FObjectDialog extends JDialog implements ActionListener {
private static String name;
private static String text;
private JTextField fName;
private JTextArea fText;
private JButton bAdd;
private JButton bCancel;
private FObjectDialog(Frame parentFrame) {
super(parentFrame,"Add an object",true);
// build the whole dialog
buildNewObjectDialog();
setVisible(true);
}
@Override
public void actionPerformed(ActionEvent ae) {
if(ae.getSource()==bAdd){
name=fName.getText();
text=fText.getText();
}
else {
name=null;
text=null;
}
setVisible(false);
dispose();
}
public static String[] showCreateDialog(Frame parentFrame){
new FObjectDialog(parentFrame);
String[] res={name,text};
if((name==null)||(text==null))
res=null;
return res;
}
}
As I said, that works properly, but I guess that might raise serious concurrency issues...
Is there a cleaner way to do that ? How is it done in JOptionPane ?
