java-programmer, How can I know which button is clicked in JDialog ShowModal Hi, all,
In a programme using swing (homework), I use a JDialog window. There are
two buttons on this dialog window. I want to write the program in this way:

// some thing
JDialog d = new ...
...
d.setModal(true);
d.show();
if (d.close = btnOk){
...
} else if (d.close == btnCancel){
...
}

In fact I want to use this way like in the windows programming:
int i = d.showModal();
if (i == ok){
...
} else if ( i == cancel){
...
}

Please help me. I am a newbie in swing programming.

Thanks a lot.

Make your own subclass of JDialog that has such a method, and return a
value from it that you test. Preferrably against a constant like an
int, and not against a component. Example:

public class MyDialog extends JDialog {

public static final int OK = 1;
public static final int CANCEL = 2;
int returnValue = 0;

JButton okButton = new JButton();
...

okButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
returnValue = OK;
hide();
}
}

public int showModal() {
setModal(true);
show();
return returnValue;
}
}
