Hi all,
I just ran int this issue where I'm trying to fill a model via
QRunnable, but when I do so, it seems to add extra rows for some
mysterious reasons.
If I run the respective process in in the main thread I get the expected
results.
Can somebody please help?
Test code attached.
Cheers,
frank

path = '/tmp/exampleTree2'
sub_dirs_dict = {}
for cur_root, cur_dirs, cur_files in os.walk(path):
if not model.rowCount():
# first iteration - add item to model
cur_root_item = QtGui.QStandardItem(cur_root)
model.appendRow(cur_root_item)
else:
# subsequent iterations need to look up the item
# from previous iterations through sub dirs
try:
for item in sub_dirs_dict[os.path.dirname(cur_root)]:
if item.data(QtCore.Qt.DisplayRole) == cur_root:
cur_root_item = item
# remove the item from the list
sub_dirs_dict[os.path.dirname(cur_root)].remove(item)

# if no keys are left delete the dictionary
