I can detect whether the user is checking or unchecking the checkbox via mouse click by connecting the itemClicked signal on the QTreeWidget. But how would I do the same if the user toggled the checkbox state by pressing the spacebar on their keyboard? I tried connecting the itemActivated signal, but it doesn't have any effect. The UI I'm building requires that I check for the checkbox state change as soon as it happens, so going through all the checkboxes in the dialog's accept() event handler method is not a viable solution.
