How to get a signal each time an item is dragged in a QListWidget.
-
I have a custom QListWidget for my GUI based application, I want to have a signal each time I drag an item inside the QListWidget. I read somewhere about using the signal something like new row added of model of the QListWidget but I am not so clear about it.

For your listWidget are you overriding the methods like startDrag() , dragMoveEvent(), dropEvent()
If yes, then you can easily emit a signal when calling startDrag() function.

Yeah i have them, which signal should i emit?

You can create your own signal and then emit it when you are calling startDrag()
Eg.
.h@signals:
void itemDrag();@.cpp
@void yourListView::mouseMoveEvent(QMouseEvent *event)
{
.....
.....
int distance = (event->pos()- dragPoint).manhattanLength();if (distance >= 4) // QApplication::startDragDistance()
{
emit itemDrag();
startDrag(Qt::MoveAction);
}
}@you can also emit inside startDrag() function as per your convenience, then connect the signal of your list to the slot where you want to handle the implementation.
