[jira] Updated: (HARMONY-4658) [classlib][swing][compartibility]
The order of ItemStateChanged events in buttonGroup is differs from RI
[ https://issues.apache.org/jira/browse/HARMONY-4658?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmitry Irlyanov updated HARMONY-4658:
-------------------------------------
Description:
The order of itemStateChanged events is different for RI and for our implementation. It isn't a bug because the behavior is unspecified, but some applications may rely on this issue
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.AbstractButton;
import javax.swing.ButtonGroup;
import javax.swing.JRadioButton;
public class Test {
public static void main(String[] args) {
ButtonGroup group = new ButtonGroup();
JRadioButton b1 = new JRadioButton("First");
JRadioButton b2 = new JRadioButton("Second");
group.add(b1);
group.add(b2);
b1.setSelected(true);
ItemListener buttonListener = new ItemListener() {
public void itemStateChanged(ItemEvent e) {
AbstractButton rb = (AbstractButton) e.getSource();
System.err.println(rb.getText() + " state changed");
}
};
b1.addItemListener(buttonListener);
b2.addItemListener(buttonListener);
b2.setSelected(true);
b1.setSelected(true);
b2.setSelected(true);
b1.setSelected(true);
}
}
Output:
RI:
First state changed
Second state changed
Second state changed
First state changed
First state changed
Second state changed
Second state changed
First state changed
Harmony:
Second state changed
First state changed
First state changed
Second state changed
Second state changed
First state changed
First state changed
Second state changed

Harmony:
Second state changed
