Python 2.7.4x32, Qt 4.8.4 (4.10.2-py27)x32 on Windows 7 64-bit OS PC's
(multiple machines)
I'm having a reproducible APPCRASH (in QtGUI4.dll) on exit of any
application I write that uses a QMainWindow and a menuBar, if the window
contains > 10 other widgets.
If I remove widgets down below the threshold (10), app closes normally.
Whether I write it by hand or in QTDesigner, but if I include a menubar,
blank or otherwise, App does not close properly in Windows resulting in a
'close program' Windows dialog.
This happens on all 3 of my Windows 7 boxes here, but works fine in a
instance of Windows XP on an older machine. (Same PyQt/Python versions)
An example with code would be I create a QMainWindow in QT Designer, put 12
widgets of any combination on it. (In this example I added a menu bar in my
code, but works the same (crash) if I add it in QTDesigner.
import sys
from PyQt4 import QtGui
import ui_mainwindow as UIMW
class MainWindow(QtGui.QMainWindow, UIMW.Ui_MainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.setupUi(self)
# MenuBar testing
self.menubar = self.menuBar()
menu = self.menubar.addMenu("Test")
app = QtGui.QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
As long as my Ui_MainWindow has > 10 widgets + menuBar, I get:
Problem Event Name: APPCRASH
Application Name: python.exe
Application Version: 0.0.0.0
Application Timestamp: 51606175
Fault Module Name: QtGui4.dll
Fault Module Version: 4.8.4.0
About 10% of the time, the first time I run the app, it will not crash
until I run it again, click on some widgets, etc, and then exit.
