Create GUI for RPi

Hello gihu, yes, Qt is native in raspbian. But I think we should make some differentiation between the version 4 and 5. There si a large number of differences and I strongly suggest to approach Qt5 for first.

This week I have zero time but at this point I think that (according with spannerspencer previous discussions) it is the worth to start a Qt section with some specific embedded LInux tips and samples.

Sorry for my short answers in these days but I am following this thread and I will start supporting you asap.

Amit,

The best way to develop with Qt is installing Qt5.x suite. It is fundamental in my opinion to approach Qt 5.5 (or, better 5.6) because there are big changes and all in positive respect the last 4.8 versions. Finally the Qt 5.5 and up versions have removed the QtWebKit that was a total issue with incredible difficulties to compile by itself as it was a sort of add-on package. Especially for the embedded devices. In Qt 5.5 the external WebKit has been definitely replaced by the QtwebEngine that is Qt native. But - just for the essential changes - has a incredible difference that is an advantage but also a mess for porting: QtWebEngine is Chrome based and multithreaded by default.

The mix that you suggest of Qt and Python, trust me, it is not the best solution but it seems the easiest. I am working just to reorganise a package due this kind of approach that it is not the definitive winning solution. Please be patient, I am preparing a first series of articles that just try to put some order in the better way to connect Python, PyQt5.5 and Qt 5.5.1 for start.

Thank you very much Enrico!!!

Hi,

Had no experience in GUI development, wanted to develop a GUI to use PI as in a kiosk mode. Found that Tkinter was easy to learn and also access the GPIO pins.

Hi,

You might want to try FLTK (Fast, Light Toolkit) which also contains FLUID (Fast Light User Interface Designer). The stable release is 1.3.3 with the official website (http://www.fltk.org). Wikipedia has some external links for both FLTK and FLUID. I first ran across FLTK in Fldigi, an amateur radio software that allows data transmission and text chat via digital modes,the program is written by www.w1hkj.com/, downloadable from https://sourceforge.net/directory/?q=fldigi . You should be able to download FLTK if it isn't included in your OS release, as it is free and open-source software, licensed under GNU Lesser General Public License (LGPL) with an additional clause permitting static linking from applications with incompatible licenses.

Enjoy!

Thanks Frank!!

In the end I used Python for what I needed, I also want to try with Qt as many other have suggested, and I will try to have a look to the tools you say

Maybe balearicdynamics can chime in? He has just presented on a QT seminar.

Edit: ah, I see he already gave an update on the previous page.

Hey Jan!

I have not ignored this post. I am busy until tomorrow then I will update a serious comment here ... Actually I think it is time to start the Qt for embedded series of articles. We already discussed this with spannerspencer in past and I never forgot it but the course of events obliged me to stop this STEM project for a while... (is this a STEM project? Maybe?)

STEM includes any technology including software in my view. Looking forward to your picking this up when you get free.

I concur with that assessment. I think software is often an application of all 4 STEM disciplines.
