Hey Bay,
While its definitely helpful to have your full code in the event that
someone wants to review all of it,it would be ideal to include some concise
snippets in the actual question to establish some context. I had to kind of
scan your entire project to figure out what you were referring to and
reproduce it.
Steps to reproduce:
1. Create a sphere and select
2. Click "Add" in the qt window. Sphere entry pops into view.
3. Select entry and click "Remove". Maya crashes.
What I have found in playing with your code is that returning the
internalPointer, and accessing it from the calling view, produces the
crash. The way I normally handle returning the underlying object
represented by a QModelIndex is to use a custom role for the model and
access it through the data() attribute on the index.
## listbuild.py
class SceneGraphModel(QtCore.QAbstractItemModel):
NodeRole = QtCore.Qt.UserRole
...
def itemFromIndex( self, index ):
return index.data(self.NodeRole).toPyObject() if index.isValid()
else self._rootNode
...
def data(self, index, role):
if not index.isValid():
return None
node = index.internalPointer()
if role == QtCore.Qt.DisplayRole or role==QtCore.Qt.EditRole:
if index.column()==0:
return node.name()
else:
return node.typeInfo()
# Handle the NodeRole
elif role == self.NodeRole:
return node
## selectorGUI.py
class Selector( QtGui.QMainWindow ):
...
def remove_Object(self):
# Seems like you wanted just the first column
# so that you can retrieve the Node?
selModel = self.tree.selectionModel()
indices = selModel.selectedRows()
folders = []
shapes = []
for index in indices:
# Modified itemFromIndex will return the Node
# Alternatively, you could just do:
# node = index.data(self._model.NodeRole)
node = self._model.itemFromIndex(index)
print node.name()
Let me know if that is what you were after?
