QTreeWidgetItem checkState() signal and slot?

  • How do I implement a QTreeWidgetItem checkState() signal and slot?

    I have a child QTreeWidgetitem that I want to deliver a signal if it is checked or unchecked, so the parent treewidgetitem will uncheck too. Sort of like a full packge install, that unchecks the parent box if just one of the child boxes are unchecked.

    I'm learning signals and slots implementation without the ui, just now.

    You don't do it on the items (they are not QObject), but in the QTreeWidget using e.g.
    @QTreeWidget::itemChanged ( QTreeWidgetItem * item, int column )@

    Connect that signal to a custom slot and handle there the modification of your items.

    Hope it helps
