[PyQt] Problem with apps build with Py2exe
Some MS Windows users have problem running PyQt4 applications - exe/binary builds made with Py2exe. The problem is that Windows displays a message like this (translation from Polish) This application can't be run as it configuration is wrong. Problem may be solved by reinstalling the script. It works for some users, and for some don't (plus it's no install run.exe made from run.py).

Re: [PyQt] Learning path
I would start with whatever you have the most experience with and jump off from there. Without knowing what languages you're used to, it's hard to say. But if you're strong in Python then transitioning to PyQt is the easiest route. If you're stronger in C++ then maybe starting out with C++ is the quickest. Either way you'll need a little understanding of the structure of C++ to be able to read some of the examples and threads discussing Qt. Also, having experience with some type of gui toolkit helps. You didn't mention whether you had ever worked with one before. But if you already understand the concepts of layouts and such, then it's just a matter of learning new functionality and syntax. My background was in Python with Tkinter, so jumping into PyQt wasn't that difficult. Fortunately I'm C++ literate as well, so that opens up more help when it comes to online examples. However there's still a bit of a learning curve when trying to figure out all the data containers and views for trees/tables/etc. Other than that it's fairly straight forward. If you're completely new to gui design then start with the most basic tutorials and work your way through them to learn the concepts. If you've got some experience then the best way is to just start working through examples. I use Eric IDE with QtDesigner. When I've been stuck on the syntax of something I can just place it on the palette, generate the .py code and see what it looks like. That's worked really well for me.

Re: [PyQt] Problem with apps build with Py2exe
Hello,
Well, shouldn't py2exe include all required libraries? I'm having the same
problem here, I'll investigate some more this weekend, but if the problem is
some missing libraries there should be a way of including them in the dist
Not necessarily. For example, it will not automatically include the
QtSvg4 library because (in my installation anyways) this is considered a
system library. You can force this by overriding py2exe's isSystemDll
and creating a list of dll's you want to include automatically in your
setup.py script. I use the following code below.When py2exe is
checking which dll's should be included, it first asks if they are
system dll's; if so, they will not be included (since a system dll
should be on the system by default?).
My guess is that it needs to be forced to include msvcp90.dll or
something. If it is a dll like the MS VC Runtime DLL then that needs to
be included along side your exe (not packaged within it or it's
library). I would say in your setup.py script to manually copy it to
your dist folder.
Darryl

Example (originally from
http://eli.thegreenplace.net/2008/10/09/packaging-dlls-with-executable-made-by-py2exe/):
-
# Override the function in py2exe to determine if a dll should be included.
dllList = ('yourLibraryName.dll')
origIsSystemDLL = py2exe.build_exe.isSystemDLL
def isSystemDLL(pathname):
if os.path.basename(pathname).lower() in dllList:
return 0
return origIsSystemDLL(pathname)
py2exe.build_exe.isSystemDLL = isSystemDLL

[PyQt] KHTMLPart mouse events
Jim, Simon, I hope you can help me. I am trying to track a user's MidButton mouse click to track paste actions. It seems that khtmlMousePressEvent (khtml::MousePressEvent* event) is the right place to do that, but the sip-file does not have those mouse event methods, they are commented out. Can that be changed in a later version? Is there a reason for them not being activated? The KHTMLPart itself does the MidButton action in these methods[1].

I suspect that khtml::MousePressEvent is not a class that's exposed in the public KDE API - meaning it's declared in some file that PyKDE doesn't wrap. So if you got one, you couldn't do anything with it anyway, since it's not a wrapped class. However, there are mouse events (QMouseEvent) available in KHTMLView, and you can get the KHTMLView object from the part by calling it's view() method. Don't know if those will do what you want, but it seems like they should. Jim ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] QVariant.toPyObject semantics
Hi all, I've a question about QVariant toPyObject method. I want to store a dict in a QVariant (i hate QVariant, but i need them for QSettings and Qt.UserData in QListWidget...) i try to make an interface for converting all the python types in qt types and store the qt types in QVariants but it doesn't work on linux (on mac os x it works fine). I decide to try the toPyObject method. On linux, when i store a dict in a QVariant and i call the toPyObject method it returns exactly the python types found in the stored dict. In mac os x, with the same dict, when i try to retrieve it with the toPyObject method it returns a dict with all the python strs (or unicodes) converted in QStrings and it converts when it can, all the python types in qt types. Why the same method has a different behaviour on Linux and Mac OS X?
