Hi,
I was asked to report this behaviour to the "PyQt Folks" and this is the best
adress I could come up with. :)
Using multiple inheritance with one predecessor being a Qt widget and the
other being a new-style class causes a segmentation fault upon instanciating
the combined child class.
-- example --
from qt import QWidget, QApplication
import sys
class A:
����def�__init__(self):
��������print�"in�A"
class B(object):
����def�__init__(self):
��������print�"in�B"
class C(QWidget,A):
����def�__init__(self):
��������QWidget.__init__(self)
��������A.__init__(self)
��������print�"in�C"
class D(QWidget,B):
����def�__init__(self):
��������QWidget.__init__(self)
��������B.__init__(self)
app = QApplication(sys.argv)
C() #works
D() #fails
-- example --
The versions where this behaviour occurs:
Python 2.3.3
>>> qt.PYQT_BUILD
'180'
>>> qt.PYQT_VERSION
198656
>>> qt.PYQT_VERSION_STR
'3.8'
Another thing I'd like to report:
pyuic makes a mistake when compiling the source of Qt Designer interface file
when the widget in the .ui file contains a toolbar with a Spacer object.
pyuic "forgetts" a "self." infront of the Toolbar object:
-- snip --
$ python LMCMain.py
Traceback (most recent call last):
File "LMCMain.py", line 65, in ?
main = LMCMain()
File "LMCMain.py", line 39, in __init__
LMCMainBase.__init__(self, parent, name, fl)
File "/home/merkosh/Projekte/LMC/LMC/GUI/LMCMainBase.py", line 1721, in
__init__
QApplication.sendPostedEvents(Toolbar,QEvent.ChildInserted)
NameError: global name 'Toolbar' is not defined
-- snip --
The lines in question yield:
-- snip2 --
spacer = QSpacerItem(0,0,QSizePolicy.Expanding,QSizePolicy.Minimum)
QApplication.sendPostedEvents(Toolbar,QEvent.ChildInserted)
Toolbar.boxLayout().addItem(spacer)
-- snip2 --
In both cases this should be
spacer = QSpacerItem(0,0,QSizePolicy.Expanding,QSizePolicy.Minimum)
QApplication.sendPostedEvents(self.Toolbar,QEvent.ChildInserted)
self.Toolbar.boxLayout().addItem(spacer)
I hope you will find this information usefull. If you need any other
information, please feel free to contact me.
Not to forgett: Thanks f�r PyQt!
Ciao
Uwe
