PyQt4中QListView的clicked（）信号

Question

I have a working QListView, but from the documentation, I can't figure out how to get a signal to fire with the index of the newly selected item. Any ideas?

Answer 1

恕我直言，更简单的方法是使用QListWidget而不是QListView，这样您可以使用itemClicked信号，该信号将选定的项目发送到回调函数。

Answer 2

These is a snipplet of code of how I achieved it:

class VenueList(QListView):
    def __init__(self, parent, venues):
        super(VenueList, self).__init__(parent)
        self.clicked.connect(self.venue_selected)
        [...]

    def venue_selected(self, index):
        venue = self.model().data(index, VenueListModel.VenueRole)
        doStuff()

You can browse the full code of how I used this here (line 69). I do warn you, however, that this code is pretty bad, and needs some serious refactoring.
