Counting the QListWidget Items by a QLineEdit each Drag&Drop event.
Hello Qt devs, I'm pretty new to qt and I would like to ask for a simple problem:
_ I have a MainWindow with:
+ An initial widget for storing initial items.
+ 10 list widgets for storing dropped items.
+ A line edit inside a for showing a "count" variable which count how many items in there.
What I want to do is after dropping a item in these 10 widgets, the "count" number plus one, and dragging an item outside the list widgets the "count" minus one. I tried eventFilter but after installingEventFilter to a widget, the dropped item dissappears. I have stuck at this for many hours so hopefully someone could give me a solution.
Re: Counting the QListWidget Items by a QLineEdit each Drag&Drop event.
You don't need any event filter for that.
Each list widget has a model for its data and each model has signals for when it adds or removes items.
Simply connect to these and update the count.
Cheers,

Can you tell me what is this Signal, is this viewportEntered or Entered. Thanks for your reply.
