    Question How to cancel pending signals?

    I have a QTreeWidget. When the user selects an item (of type QTreeWidgetItem) and presses the Delete key, a slot is invoked on this item to delete itself.

    Under certain circumstances, deleting an item might take long enough for the user to press Delete a second time on the same item, leading in my case to a crash.

    What is the best way to handle this situation?

    I'm using Qt 4.8.6.
