I am trying to switch from PySide to PyQt.
The following code seemed to work in PySide:
class FramedViewedTextGlyph(CompositeGlyph, ViewSizeable, Proxiable,
QGraphicsItemGroup): # no class inherits QObject
def __init__(self):
super(FramedViewedTextGlyph, self).__init__() # init group
This is an update to my previous post.
Here is an abstract of the code for easier reading:
class B(object):
def __init__(self):
self.a1 = A()
self.a1.signal1.connect(self.handler)# Fails in PyQt, succeeds
in PySide
def handler(self):
pass
class A (Mixin,
'parent = None' in Python means: a keyword argument, keyword is
'parent', default value is None. (That's basic knowledge of Python.)
But note that the PyQt documentation requires a little more
interpretation because: it is automatically derived from the C++ Qt
documentation. Thus 'QWidget
I haven't done much exploration as to why.

More information:
Apparently no errors during build but the .so is missing after install.
In the build directory, after a build:
Exists:
cfgtest_QtSvg.pro and .cpp
Not exists:
cfgtest_QtSvg.o and .exe and no QtSvg directory
I am not very familiar with sip and the PyQt and Qt build processes.
I determined that QtSvg is not a subtarget in the Makefile.
I will assume that is intended and that I shouldn't be using a
snapshot. I will regress to the released PyQt5.1.

The solution is to ensure that the distribution's package for QtSvg
development is installed.
On Ubunutu 13.04, installing package 'Qtcreator' is not enough.
You also must install package 'libqt5svg5-dev'.
(A decision made by Ubuntu packagers?)
The symptoms (in my case) started with a Python
This code worked in PyQt4 and Qt4 to get a dictionary of paper size names:
paperSizeNames = {}
print(vars(QPrinter))
for key, value in vars(QPrinter).items(): # Python2 iteritems():
if isinstance(value, QPrinter.PageSize):
print(key, value)
paperSizeNames[value] = key
It no longer
The QPageSetupDialog fails to appear, or is empty and small.
I posted code that demonstrates the problem at:
http://qt-project.org/forums/viewthread/33589/
I also tried parenting the QPageSetupDialog (doesn't that make PyQt own it?)
It seemed to work before I upgraded from Qt 4, but I might
