In my Java swing application i have noticed that when i click on a disabled JMenuItem in a JPopupMenu it hides the menu, but i i do not want to hide it, as if nothing is clicked. Is there a way to prevent this ?
-----------------------------------> Update: Added Code sample :
JMenuItem saveMenuItem = new JMenuItem();
saveMenuItem.setEnabled(false);
saveMenuItem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
saveMenuItemActionPerformed();
}
});
add(saveMenuItem);
private void saveMenuItemActionPerformed() {
System.out.println( "Save clicked." );
}
This has been tested and works.
The Look & Feel decides how to handle the mouse events on disabled menu items. Anyway, you can intercept the undesired events by using a custom MenuItem. Simply use that code (copy/paste):
public class CustomMenuItem extends JMenuItem {
public CustomMenuItem(String text) {
super(text);
}
public CustomMenuItem() {
super();
}
protected void processMouseEvent(MouseEvent e) {
if (isEnabled()) super.processMouseEvent(e);
}
}
First, adapt the code to suit your needs (optional).
Finally, replace any JMenuItem with a CustomMenuItem.
That's it!
