Hi, i have an application built on python and PyQt with many forms, and i just switched it from the old QWorkspace to QMdiArea.
i am openning forms with this code:
def addSubWindow(self, form):
new_sub = QMdiSubWindow()
new_sub.setWidget(form)
new_sub.setAttribute(Qt.WA_DeleteOnClose)
self.mdi.addSubWindow(new_sub)
form.show()
and when the form is closed it coles this function:
def formClosed(self):
window = self.mdi.activeSubWindow()
self.mdi.removeSubWindow(window)
the problem is when i open lots of windows and then closing them and then reopen the system crashes with out an error, it happens at random not always with the same form.
i run it with gdb and it gave me the following:
Program received signal SIGSEGV, Segmentation fault.
0x618945a9 in QtGui4!?takeAt@QBoxLayout@@UAEPAVQLayoutItem@@H@Z ()
from c:\python\python27\lib\site-packages\PyQt4\QtGui4.dll
i am working on windows 7 Python 2.7.3, Qt 4.8.4, PyQt 4.9.6
