Call QObject.sender() in the slot method.

[PyQt] help with this question

[Rafael Lemus]

Hello,

I've been wondering if there is a pyqt method that can tell me which was 
the widget that sent a signal, this is because I want, that whenever a 
QPushButton is
 clicked it sends me to a method and in this method I could compare 
which button send me a signal so i can emit another signal.
thanks in
 advance

I've had another report like this. Two possible solutions - use the current
PyQt snapshot, or use Python 2.6.4.

Not if you are using Qt v4.6.1. You must have an older version of the Qt
libraries installed as well.

[PyQt] PyQt and/or Qt problems on Windows Vista

[Francesco Biccari]

Hello,

this is my first post to this list.
I am an Italian researcher. In our lab we would like to move
from Visual Basic (5!) to Python + PyQt.

Unfortunately our first tests were discouraging and I am here to
ask for some advices.

I use Windows Vista 32 bit.
I installed Python 2.6.5 (Windows installer) and
PyQt (PyQt-Py2.6-gpl-4.7.2-1.exe).

We have noticed two issues:

1. programs written with PyQt run slower
than similar programs written, for example, with wxPython.
(however this is not a big issue)

2. All non-trivial PyQt applications make python.exe to crash when we
close the application.

I tried also to compile PyQt by myself but the problems still remain.

Here there is an example of application which show these problems:
http://eli.thegreenplace.net/2009/12/12/tetris-implemented-in-pyqt/
another application is Eric4.

Thank you in advance for your help.
Regards.
Francesco

Re: [PyQt] "sip: QFileIconProvider is undefined" from import of QtGui/QtGuimod.sip with SIP 4.10, Qt 4.6.1 and Python 2.5.1

[mfloyd]

Excerpt from our pyqtconfig.py script is below.  The Qt string generated for 
pyqt_sip_flags from a Qt 4.6.1/PyQt 4.6.1 installation is 'Qt_4_5_0' - which is 
puzzling to all of us who were expecting to see something like 'Qt_4_6_x'.  Is 
the appearance of '-t Qt_4_5_0' for 'pyqt_sip_flags' in the Qt 4.6.1/PyQt 4.6.1 
installation expected behavior?

Thanks,

Works fine for me. It suggests a problem with your PyQt installation. You
can check 'pyqt_sip_flags' in pyqtconfig.py to see what flags you should be
using.

Thanks darren for your reply. But still i couldn't make it to work.

This is what i did. Installed the qt-mac-cocoa-opensource-4.6.0.dmgfrom the

$make and $make install.

Then after extracting PyQt-mac-gpl-4.7.tar.gz the $python3 configure.py
produces the following error..

Re: [PyQt] pyrcc4 query

[Clément Mairet]

Anshul Jain wrote:
Please tell me if there is any other possible way to create a resource 
file without the pyrcc4 command.


Hi!

Wondering the same thing a while back, we tried coming up with a Python
alternative to pyrcc for the Spyrit project, mostly as an exercise to
easily package and compress our resources in a slightly smaller file
format, and allow users to do so from our application itself -- for
instance to re-generate themes and so on.

We put together our own Python implementation of pyrcc4
for convenience, which generates similar output as pyrcc4 when used with
the '--legacy' option -- our version is as yet incomplete as it doesn't
handle resource subdirectories at all, nor does it use Qt compression
yet. It does work for simpler cases, however.

You can find the code in the Spyrit sources, it works as a standalone
script but should be easy to adapt to other uses:

http://spyrit.hg.sourceforge.net/hgweb/spyrit/spyrit/file/cd759ccf86a7/resources/spyrcc.py

It's probably a suboptimal implementation, and I'd also be curious to
know of similar -- and more mature -- tools in Python.

Hope it helps,

-- C.
