Error changing edit targets

[csaez]

Hi there,

Looks like the dataChanged signal fails to get emitted on PyQt5 (it work on PySide, PySide2 and PyQt4).

Traceback (most recent call last):
  File "/home/users/cesars/packages/usd_qt/0.a.3/lib/python/pxr/UsdQtEditors/outliner.py", line 269, in ChangeEditTarget
    self._stage.SetEditTarget(newLayer)
  File "/home/users/cesars/packages/usd_qt/0.a.3/lib/python/pxr/UsdQtEditors/outliner.py", line 123, in _OnEditTargetChanged
    self.dataChanged[QtCore.QModelIndex, QtCore.QModelIndex].emit(
KeyError: 'there is no matching overloaded signal'

Repro:

• Run the outliner
• Tools > Change Edit Target
• Double click on Kitchen_set.usd (or any non active layer)

Here's the code I'm using to run the outliner:

import sys
from Qt import QtWidgets
from pxr.UsdQtEditors import outliner

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    filepath = './usd_kitchen/Kitchen_set.usd'
    d = outliner.UsdOutlinerDialog.FromUsdFile(filepath)
    d.show()
    sys.exit(app.exec_())

Environment:

• PyQt-5.9.0.1
• Qt_vfx-5.6.1.7.0
• Qtpy-1.1.0
