I think only moderators (myself) can edit posts. But no reason to do it as

Lets just look at this snippet specifically:
def populateSourceItems(self):
sourceItems = pm.ls(sl=1)
# items currently listed in QListWidget
lst = [i.text() for i in self.sourceWidget.findItems("",
QtCore.Qt.MatchContains)]
for i in sourceItems:
item = QtWidgets.QListWidgetItem("%s" % i)
self.sourceWidget.addItem(item)
You have full control over what value from your PyMel objects that you want
to add to your widget. So it shouldn't matter if its the cmds module,
PyMel, the API, or whatever. You just have to choose if you are going to
convert it to a string, or specifically use the shortName() vs longName().
If you are currently just dumping all of the list values, why not check if
you already have it in the list before adding it?
# items currently listed in QListWidget
existing = set(i.text() for i in
self.sourceWidget.findItems("", QtCore.Qt.MatchContains))
for i in sourceItems:
text = str(i)
if text in existing:
continue
item = QtWidgets.QListWidgetItem(text)
item.setData(QtCore.Qt.UserRole, i)
self.sourceWidget.addItem(item)
As you can see, you could also store the PyMel node on the item so that it
could be retrieved later via item.data(QtCore.Qt.UserRole)
