currently I'm doing the PyQT Model View Programming Tutorial by Yasin
Uludag. As I'm new to PyQT I'm still unfamilar with how to get information
out of pyqt and back into Maya again. Currently I'm doing the Treeview part
of the tutorial trying to figure out how to interpret a name change in the
menu into an actual rename for the object.This is the setData method for
the model class
def setData(self, index, value, role=QtCore.Qt.EditRole):
if index.isValid():
if role ==QtCore.Qt.EditRole:
node = index.internalPointer()
node.setName(value)
return True
return False
and this is the setName method
def name(self):
return self._name
How do I convert the value in node.setName(value) into something that Maya
could read so that I could use it for a cmds.rename? Attached is also the
full script in case that information is needed.
Thanks for any suggestions given.
