Setting up PySide/Qt for GUI development

Question

I have been trying to setup PySide/Qt for use with Python3.3. I have installed

PySide-1.2.0.win32-py3.3.exe 

that I took from here and I have installed

qt-win-opensource-4.8.5-vs2010

that I took from here.

I generated .py files from .ui files (that I made using QtDesigner) using pyside-uic.exe as is explained in PySide Wiki.

Making .py files was working when I was using Qt5.1/QtCreator. I stopped using it when I found that I need to use Qt4.8 as explained on Qt-forums. With Qt4.8 it isn't working.

• I want to develop GUI using PySide.
• I want a drag-and-drop interface for making a skeleton GUI so I am using QtDesigner.
• I am on Windows 7

I want to package the GUI developed into .exe files using cx-freeze.

My problem in short
What are the correct tools to use to make .ui with QtDesigner? How to convert them to .py files for use in Python using PySide?

cx_freeze is able to make my normal files to .exe Can it be used to convert the GUI made by Qt/PySide into .exe files? Would Qt be needed on other computers where the .exe of the GUI is distributed or would it be self-contained?

I used

cxfreeze testGUI.py  --include-modules=PySide

to make the exe and related files. A directory dist was created with many files. On running nothing happened. So I used command line to find out the reason. The errors are

Traceback (most recent call last):

    raise WinError()
FileNotFoundError: [WinError 3] The system cannot find the path specified.

Anyone knows what this stacktrace means?

There is a lot of win32 in here. But I have Windows 7 64-bit. I am using 32-bit Python and all modules were installed 32-bit. Could that cause a problem? I don't think it should as other exe I made for simple Python scripts were executing fine.

Answer 1

This error:

FileNotFoundError: [WinError 3] The system cannot find the path specified.

will be fixed in next pyside release (1.2.1). It will be released in next week.

btw: in case you don't want to generate custom bindings, you don't need to install qt, pyside installer contains all qt libraries and devel tools.
