Hi all,
Perhaps a stupid question. Some time ago, I received a rpi zeroW as a gift, but as I did not have any use for ii I passed it to somebody else in our electronics-group. Now, that person has had a +30 year carreer as self-taught programmer -starting out with BASIC on DOS machines- so he showed of some of his old BASIC applications in dosbox on the pi.
So far so good, but he had an interesting question: Years ago, I wrote a library in BASIC for screen / window applications in DOS. (you know, pop-up text-windows and so on). How do I do that on linux (in C)?
As I myself only do ‘backend’ coding (so no UI), I have to admit I did not have any answer to that.
So, question, For somebody who has mostly coded in BASIC (first DOS and later Visual Basic) and now switched to C and python, what is the best / most easy tool to write a basic UI application with window-function on linux/unix. I know there exist things like QT and ncurses, but I never used these, so I have no idea.
Any advice?

For text, I agree with others, ncurses
For graphical
- pyGTK
basically everything you need, some learnig curve as it’s big and versatile. But to be honest, when trying to achieve something I’d suggest to start from GTK reference to me it somehow conveys the logic better than the PyGTK reference - Kivy
haven’t used it, but might be fun to use - wxWidgets
very cross-platform. Not only you can use it to write UI that will require minor fixes to have the same code for Windows and Linux at the same time, you can also tell it whether the toolkit used under the hood on Linux should be QT or GTK - Tk
old, simple (more fancy things need some gymnastics) but simple (easy to use) and supported in Python out of the box (you don’t even need to install anything) - QT
I’m putting it here just for fairness. I don’t like it, don’t like its signal-slot design, I think it’s hogging up too much resources. But last time I used it was ~10 years ago and in the end, it does in fact work
Wauw! So many answers in such a short time. Thanks all! 👍 (I will not spam the channel by sending a thank you to all but this is really greatly apriciated)
Concerning ncurses. I did hear of it but never looked at it myself. What is not completely clear for me. I know you can use it for ‘low-level’ things, but does it also include ‘high-level’ concepts like windows, input fields and so?
The blog mentioned in one of the other posts only shows low-level things.
but does it also include ‘high-level’ concepts like windows, input fields and so
Yes, it allows you build full on TUIs.

AFAIK MC uses ncurses for GUI. So I while I don’t know if it has the concept of non-modal dialog, for example, for sure it has dialogs, fields, radios, boxes, etc
- pyGTK
If you want a terminal gui, then ncurses may be suitable which you can also use in c++. Qt and Gtk have c++ bindings.
I’d recommend egui, though you have to use Rust for it. (learning it should be easy, considering the fact that you have background in C).
Both GTK and Qt have good Python bindings.
GTK example: https://github.com/Taiko2k/GTK4PythonTutorial
There’s also PyQt but it looks more complicated and I couldn’t find as nice and straightforward of an example as GTK but I found this: https://realpython.com/qt-designer-python/
If you want to go to C, GTK works about the same way. If you want C++, Qt is pretty good there.
Otherwise you can go SDL and just put whatever pixels you want on the screen on your own.

I’d go for ncurses.
Raygui, fltk, GTK. Qt if you’re working in C++
I class myself as having similar experience to your friend having used Power Basic and Turbo Pascal mainly under DOS. I was able to use tkinter to produce some simple gui front-ends to produce dialogue boxes, process data and feed it to GnuPlot.
You don’t
Use existing frameworks like GTK and QT
FOr me the quickest and basic way would be python and tkinter or pyqt. Failing that, push it to a web app with something like Flask or React
It really depends on which language you want to use.

There is also
newtwhich is: …a programming library for color text mode, widget based user interfaces.It also comes with the
whiptailcommand for creating TUI interfaces for shell scripts. Similar todialog(ncurses) orzenity(QT).I’ve used pyTK to make some apps for personal use. Good stuff, somewhat easy to use once you follow some tutorials.
I’m not that deep into the topic, but I experimented with GTK and tkinter as a kid
Easiest GUI toolkit I’ve used was NiceGUI. The end result is a web app but the python code you write is extremely simple, and it felt very logical to me.
