That is exactly what I need. Learned something new today. Great!
One more thing though, I want to edit the text of the item. The text
reverts back to original after edit. I am trying adding setData on the
Custom item type with no success. Did search a hell lot on the Internet for
an answer before posting here.
class CustomItem(QtGui.QListWidgetItem):
USER_TYPE = QtGui.QListWidgetItem.UserType + 1
def __init__(self, customitem, parent=None):
super(CustomItem, self).__init__(parent, self.USER_TYPE)
self.customItem = customitem
def data(self, role):
if role == QtCore.Qt.DisplayRole:
return self.customItem.name()
elif role == QtCore.Qt.EditRole:
return self.customItem.name()
return super(CustomItem, self).data(role)
def setData(self, role, value):
if role == QtCore.Qt.EditRole:
self.setText(value)
print value
#self.setData(QtCore.Qt.DisplayRole, value)
The print command goes through, so setData is working. Is it possible to
edit the text even after we set the data to return the object name?
Another solution would be to revert to a regular text list for the
right-side listWidget that only contains names and not objects(custom type
subclasses).
