From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

basic UI programming in linux (infosec.pub)

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?

So it's graphical interface we are after or text based?

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.

For higher level widgets in ncurses, you can use a library like textual or urwid.

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
