[PyQt] QStackedLayout addWidget always returns 0

[Lee Harr]

My understanding is that QStackedLayout.addWidget should add the
widget to the end of the stack and return the index of the position at
which it was added.

For some reason, I am always getting 0...

Versions:
Ubuntu 4.10
Python 3.4.2 (default, Oct  8 2014, 13:18:07) [GCC 4.9.1]
PyQt 4.11.2


Example:
import sys
import PyQt4
from PyQt4.QtGui import QWidget, QApplication, QLabel, QStackedLayout

 
class QSLayoutExample(QWidget):
    def __init__(self):
        QWidget.__init__(self)
 
        self.layout = QStackedLayout()
        self.setLayout(self.layout)
  
        for i in range(10):
            w = QLabel(self)
            idx = self.layout.addWidget(w)
            print(idx)
            print(self.layout.count())
 
    def run(self):
        self.show()
        qt_app.exec_()


qt_app = QApplication(sys.argv)
app = QSLayoutExample()
app.run()



Output:
0
1
0

0
3
0
4
0
5
0
6
0
7
0

Am I using this wrong? Are my expectations mistaken?


Thanks for any insight.
