Qt Code: 
  1. void MyTreeWidget::contextMenuEvent(QContextMenuEvent* event)
  2. {
  3.     QTreeWidgetItem* item = itemAt(event->pos());
  4.     if (item)
  5.     {
  6.         // an item exists under the requested position  
  7.         QMenu menu(this);
  8.         menu.addAction (chatAction);
  9.         menu.exec(event->globalPos());
  10.     }
  11.     else
  12.     {
  13.         // there is no item under the requested position
  14.     }
  15. }

I've subclassed QTreeWidget in order to create a context menu and what I want to do is to exclude some commands from the context menu in case an item from the tree is expandable. Like I have an item that's a group and its subitems are users and I don't want to have the option "Rename" on the user item but I want it on the group item.
So is there like a item->isExpandable () method, or is there any way I could implement something like that? I know there's a isExpanded () method but it checks whether the item is expanded not expandable.

I've checked here and didn't find anything useful.

I hope I made my question clear enough.

Thanks.
