On January 24 started a thread, entitled "using QProcess to run a python function." It was a discussion about communication between an extant CLI python program and a GUI to be developed for it. I found it interesting, but was disappointed that in the end no coded examples were offered.
In the simplicissimus bunch of elementary tutorials that I wrote, ref: http://qt-project.org/wiki/PySide-Newbie-Tutorials there is one tutorial, named "Engineering Application", ref: http://qt-project.org/wiki/PySide_Engineering_Application which is an example of a simple interface between a CLI style Python program (ncrunch.py) and its GUI (truss.py). Whilst the text of these tutorials has not been updated yet, the programs have been updated and placed in one repository on "github", named "tuts4pyside" ("Owner" OldAl). All the blobs in the repository can be cloned by anybody with the git command: git clone https://github.com/OldAl/tuts4pyside To run the programs one needs to install numpy (python-numpy) in addition to pyside. The CLI program can be run, after changing the work directory to "tuts4pyside/truss" in your local repository, with the command python ncrunch.py Alternatively, the GUI version can be run by python truss.py Refer to README.md in the same directory for further information. The "secret" of this dual entry to the program is a little function "printline". When the ncrunch.py is started from CLI, printline prints on stdout. When ncrunch.py is used as a module of "truss.py", printline is passed as a parameter to ncrunch.py, where it prints on the "Solution Page" of the GUI. Simple, when one thinks about it. It seems to me that many users of python programs are interested in graphical tools, such as PySide or PyQt, mainly because they want to be able to provide GUIs for their python programs. For that reason alone, it is a topic worthy of discussion. If required or desired, I can be contacted by email on this list or by private email. All feedback is appreciated. I live in Canberra, Australia, where I can also be contacted directly. Last, but not least, I want to thank Aaron Richiger who was so generous with his time and his expert advice before I was put out of action by a stroke some 6 months ago. Yes, I have mostly recovered. Also, I wish to thank "github" for hosting free of charge repositories for open source programs, including "tuts4pyside". OldAl (Al.
