Thanks Justin for the quick reply.
I wanted the QListWidgetItems to be editable. Didn't know how to use the
"setFlags" on the item, so I put each object as a QListWidgetItem, made it
editable and added to the new list. I realize now it was not a good idea.
Found another way to do that.
I have replaced this code:
for obj in load_objs:
obj = QtGui.QListWidgetItem(obj, parent=self.ui.preview_new_names_list)
obj.setFlags(QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsSelectable |
QtCore.Qt.ItemIsEnabled)
self.ui.preview_new_names_list.addItem(obj)
self.newList.append(obj)
With this:
for index in xrange(self.ui.preview_new_names_list.count()):
item = self.ui.preview_new_names_list.item(index)
item.setFlags(QtCore.Qt.ItemIsEditable |
QtCore.Qt.ItemIsEnabled |
QtCore.Qt.ItemIsSelectable)
It works now. No more stale objects.
There was another train of thought while implementing this. I was trying to
find out a way to store object info instead of just the text. I'm using
PyMel. I want to retain the actual object while adding the name to the
lists. (To avoid duplicate named objects)
Is there a way I can handle duplicate named objects?
Can i store the actual object(in this case a pymel transform node) with the
list and give it a title?
Currently I have it working by making another list which holds the actual
objects when the objects are loaded in the lists by the "Load Objects"
button.
loaded_objs = []
def load_objs():
selected_objs = pmc.selected()
objs_to_process = []
for obj in selected_objs:
obj_name = _get_short_name(obj)
objs_to_process.append(obj_name)
loaded_objs.append(obj)
controller.objList.emit(objs_to_process)
def custom_rename(old_list, new_list):
for i in range(len(old_list)):
obj = pmc.PyNode(loaded_objs[i])
_do_rename(obj, new_list[i])
The short name of the objects get added to the list while the object is in
the "loaded_objs" variable.
(_do_rename is just a proc i made to rename objects with some error
checking)
Is there a better way to do this?
