Is it possible to create a signal for when a QTreeWidgetItem checkbox is toggled?

Question

I've created a checkbox that's also a QTreeWidgetItem using the code below.

//Populate list
QTreeWidgetItem *program = createCheckedTreeItem(QString::fromStdString(itr->first), true);
treePrograms->addTopLevelItem(program);

---

QTreeWidgetItem* ConfigDialog::createCheckedTreeItem(QString name,bool checkBoxState)
{
  QTreeWidgetItem *item = new QTreeWidgetItem(QStringList(name));
  item->setFlags(item->flags()|Qt::ItemIsUserCheckable);
  if (checkBoxState)
  {
    item->setCheckState(0,Qt::Unchecked);
  }
  else
  {
    item->setCheckState(0,Qt::Checked);
  }
  return item;
}

I need a way of connecting a signal and slot for when the state of this checkbox is changed. The current way I've implemented this is below but unfortunately doesn't work. Can someone explain what I'm doing wrong and what I need to do in order to get it to connect?

connect(program, SIGNAL(toggled(bool)), this, SLOT(programChecked(bool)));

Answer 1

Connect to the signal itemClicked(QTreeWidgetItem* item, int column) of the tree. When handling the signal, just verify item->checkState(column).

Answer 2

You have to grab the signal itemChanged ( QTreeWidgetItem * item, int column ) coming from QTreeWidget.
