Is there a signal emitted when the user changes the state of the checkbox? As far as I can tell it's not any of these:
Qt Code:
  1. // QTreeWidget
  2. void currentItemChanged(QTreeWidgetItem *, QTreeWidgetItem *);
  3. void itemActivated(QTreeWidgetItem *,int);
  4. void itemChanged(QTreeWidgetItem * item, int column);
  5. void itemClicked(QTreeWidgetItem *, int);
  6. void itemCollapsed(QTreeWidgetItem *);
  7. void itemDoubleClicked(QTreeWidgetItem *,int);
  8. void itemEntered(QTreeWidgetItem *, int);
  9. void itemExpanded(QTreeWidgetItem *);
  10. void itemPressed(QTreeWidgetItem *, int);
  11. void itemSelectionChanged();
  12. // Signals inherited from QTreeView
  13. void collapsed(const QModelIndex &);
  14. void expanded(const QModelIndex &);
  15. // Signals inherited from QAbstractItemView
  16. void activated(const QModelIndex &);
  17. void clicked(const QModelIndex &);
  18. void doubleClicked(const QModelIndex &);
  19. void entered(const QModelIndex &);
  20. void pressed(const QModelIndex &);
  21. void viewportEntered();
