QListWidget and Multiple Selection

Question

I have a regular QListWidget with couple of signals and slots hookedup. Everything works as I expect. I can update, retrieve, clear etc.

But the UI wont support multiple selections.

How do I 'enable' multiple selections for QListWidget? My limited experience with PyQt tells me I need to create a custom QListWidget by subclassing .. but what next?

Google gave me C++ answers but I'm looking for Python

Answer 1

Unfortunately I can't help with the Python specific syntax but you don't need to create any subclasses.

After your QListWidget is created, call setSelectionMode() with one of the multiple selection types passed in, probably QAbstractItemView::ExtendedSelection is the one you want. There are a few variations on this mode that you may want to look at.

In your slot for the itemSelectionChanged() signal, call selectedItems() to get a QList of QListWidgetItem pointers.

For PyQT4 it's

QListWidget.setSelectionMode(QtGui.QAbstractItemView.ExtendedSelection)
