[FIXED] Unable to Launch Qt uic

Issue

I have installed Qt designer 4.8.2, Pyside, and Python 3.3. When I create a form with Qt designer I am not able to see the code when clicking on view code. The error message is:"Unable to launch C:\Qt\4.8.2\bin\uic". I have the pyuic under C:\Python33\Lib\site-packages\PyQt4\uic. Please help.

Solution

Although you can certainly use Qt Designer for creating UIs for PySide/PyQt, you should be aware that it is primarily a C++ tool - it doesn't have any built in support for Python. So the "View Code..." command you refer to only produces C++ code - which is probably not much use to you if you intend using PySide or PyQt.

Qt Designer UI files are in an XML format (they usually have a .ui extension).

To use them with Python, there are basically two options:

1. Load the .ui files directly into your application.
2. Convert the .ui files into Python modules using an external tool.

There are several differences between PySide and PyQt in how these two options are implemented.

For PyQt, the full documention for both options can be found here.

For PySide, the documentation for option 1 can be found here - but it does not look like there is any documentation for option 2. However, the external tool for PySide (which is called pyside-uic) works very similarly to the one for PyQt (which is called called pyuic4).

If you need more general information about how to get started using Qt with Python, try the PySide Wiki or the PyQt Wiki.
