In my form I have a QListWidget which contains checkable QListWidgetItems. I’m looking for a way to capture the event of a QListWidgetItem being checked/unchecked. I don’t see any such signal existing for this but maybe I’m wrong. What I’m currently doing is using the QListWidget::itemClicked() signal and checking the checkState of the QListWidgetItem, but this isn’t what I want because this event happens any time the item is clicked, not just went the checkmark is toggled. Can anyone give some assistance? Thanks!

    Apparently no such signal is provided, your best bet is to use QListWidget::itemChanged(QListWidgetItem* item) , and scan the resulting item->checkState(). This should be a slight improvement over using itemClicked
