I am working on a ThreadX based embedded system. I want to include a 4.5 inch graphical UI to this device and hence exploring on the possible GUI library / frameworks existing for ThreadX based embedded applications - I am open for both open source and licensed frameworks.
Please help.
Thanks
Arun
Azure RTOS GUIX is probably your best bet. It's integrated with ThreadX already, has the same license, and comes with lots of examples.

I have been researching widely on this topic, but still haven't found a proper guide.
What I am doing is to create a GUI for an embedded system based on Linux Embedded and I would like to know if:
it's going to be possible to code the GUI using HTML, CSS and JS?
is it worth looking into porting a framework such as React JS?
is there any other alternative that allows for quick development and satisfying UI?
I am very new to this and I would be very grateful if someone more experienced could point me in the right direction.
Thanks so much.
I've just written an article listing the top 5 libraries for creating GUI on Embedded Linux. I've only mentioned one tool that renders HTML UI, the Sciter engine. It's much more compact than Webkit or Chromium. The owner of the project, Andrew Fedoniouk, recently released a new version called Sciter.Lite that will support embedded devices. Check out these two resources.

Demos are already available on their GitHub

You don't have to limit yourself to HTML UI, check out the other tools I've recommended. All of them have a free version. For rich UI, I think HTML UI is easier. I mean, Sciter Notes doesn't look to shabby and it's just under 5Mb for Win, Linux and Mac. But the backend is C++. For more minimal hardware, you'll have to look into the C/C++ toolkits I've listed. TotalCross are planning to support Android XML but has not been released yet. So you can check on them also.
Oh. Almost forgot. Two whitepapers comparing QML and HTML5 were published in 2017. Qt requires you to register so I'll just give you the links so that you can download them without registering :)
Paper 1: Qt QML v HTML5 –a practical comparison
Published on May 2017 by Sequality Software Engineering an Austrian firm that is a Qt partner and does Qt consultancy.
Downlink Link 1, Download Link 2
Here is a review of the paper by a software engineer, Amir Shrestha, who provided the first download link. There is more discussion at Hacker News. There was also an interesting discussion thread in a YouTube video about the comparison. You can read the YT comment section but first search "Andrew MacAulay" and read that thread. He was the lead engineer for the autopilot system for the F-18 jets and has worked in other senior embedded roles.
Paper 2: Qt or HTML5? A Million Dollar Question
Published on Oct 2, 2017, by Burkhard Stubert a Qt consultant and developer.

Here is the discussion on Hacker News.
An interesting piece of information I found in the second paper is that 90%+ of all home appliances are powered by micro-controllers with no OS or a very minimal RTOS.
Another interesting piece of information I discovered while writing my article, is that Micrium OS and components are now open-source under Apache 2.0. It has its own GUI toolkit written in C but it only targets Micrium OS and not embedded Linux. If developers start adopting Micrium OS (it was already quite popular in the industry and even launched in space) perhaps you can start looking into it too.
I'm looking for a desktop publishing platform for Mac, Windows, and Linux that is closely tied to PhoneGap in terms of the concept. I know that there's Titanium for Desktop (TideSDK?) but as far as I've used it before, it requires the end-users to download a big 70mb-ish runtime file once. What I liked about PhoneGap is that it doesn't require any of that (it works out of the box). I'm looking for something similar, only, instead of being meant for the mobile development, it 's targeted at desktop application development.
Perhaps I failed to mention it but if you are not aware of what I'm specifically talking about, I'm talking about an environment of sort that will let me code via an HTML base and output a native for said platforms. Both TideSDK and PhoneGap does this.
I would highly recommend giving TideSDK another chance, I have developed large, data driven applications on it in the past, and deployed to OSX and Windows and have personally been very satisfied with it. Also, it is now an open source project managed and maintained by a very good team with some oversight and help from Appcelerator (the original creators).
Theyre are two benefits to TideSDk as I see it:
License - TideSDK is open source licensed under a liberal Apache 2.0 license. As opposed to QT which is under the restrictive GNU Lesser Public, and commercial license.
Power - TideSDK allows you to leverage native API's (like phonegap) but access them in your favorite programming language (well, choose between Ruby, PHP, and Python). Your only options with QT are C++.
As for what you said about the 70MB runtime, this is not true, I built the runtime in with my last project, and the binary I gave to my clients (OSX) was only 15.3MB.
Hope this helps you come to a decision.
There is a way to run a PhoneGap HTML5 App on the Desktop with the help of Adobe AIR like described here: http://www.tricedesigns.com/2012/02/17/repurposing-phonegap-apps-as-desktop-apps/
But I am also looking for a less bloaty approach. Maybe based on Xulrunner/Prism/WebRT thing (or Chrome).
Tidesdk is the easiest, xml file is almost identical to the phonegap, provides powerful api and the best part you can package your app with runtime. I think you should stick to tidesdk.
I was looking for the same and found this implementation for windows ony: https://github.com/davejohnson/phonegap-windows
I did not tried it though.
We are looking to migrate our automotive diagnostic application from the PC to a Windows Embedded platform. We have an enormous application logic code base which we will migrate to the .net Compact Framework but we are struggling to decide on the UI framework. At the moment we have three options:
1) Silverlight
2) QT
3) Crank
I have a little experience in WPF so I'm naturally drawn to Silverlight but I have zero experience of the others. Have any of you used them on this platform? Can you give me some pros/cons and maybe some potential gotchas?
Cheers,
Chris.
If you are not tied to .NET and want to have a deployment choice between Windows, Windows Embedded, WinCE, Linux x86/x64 or ARM Embedded Linux you can take a look at:
fpGUI
CodeTyphon
CodeTyphon even includes complete cross platform SCADA package for visualization and communication with many protocols (MODBUS, Siemens, Allen Bradley and other PLCs).
I would like to build a graphical application that must work on at least Windows, Linux and MacOS. I would like to know what do you suggest I should use.
I have some experience with Java and C++ but I thought about using Java Swing first. What do you think or further suggest (like maybe tools or frameworks)? I also may be needing to connect to a PostgreSQL database to store data.
Java is probably the simplest way to get your application working on all 3 platforms as well as to add database support. All of these are equally possible in C++, but it definitely involves more work because you need to learn to use a cross-platform widget toolkit. Also, C++ database drivers usually have wildly varying designs but Java presents a unified interface via JDBC - this also means that you can change your underlying DB at any time without having to change your code.
I would use the Qt platform from Nokia. It supports all the OSes that you've mentioned and has also database connectors for PostgreSQL but also for MySQL, SQLite, etc.
It also has a very nice IDE, the QT Creator that you can use should you pick Qt.
I would suggest Qt too. Qt has seen very good development recently, their examples and documentation base is quite large, and the LGPL license is flexible too, for creating proprietary software. It has a good Qt Creator IDE, a Qt GUI Designer. Plus is has quite a number of modules, enabling it to be used in conjunction with other language developed apps/libraries. And, it is used in commercial/public apps like Google Earth, Skype (maybe only the linux version). So, it has a good history of reliability. And yeah, for Database, it has modules, like Qt-Sql. Another advantage you get over java is speed.
wxWidgets does cross-platform easily enough, using available native toolkits. You could probably use a ORM for the database part, but I don't have enough experience using them under C++ to provide an actual informed opinion there.
GTK is cross-platform. Pidgin uses it and manages to get away with being generally considered a fully-cross-platform app. The installer size is a problem, though.
Some of the requirements (restrictions) for such a ui framework/toolkit are:
No single vendor lock down
Ability for real time data visualization
Good initial widgets
Good dash boarding capabilities
cross platform
Good development/debug environment
No flash
It's a pity you can't/won't use Flash. Else I could really recommend Adobe AIR. It has a good editor (Flex Builder built on Eclipse), a good component framework with many out of the box components, charting components set, ability to communicate with many different protocols (and you could write your own protocol implementation), cross platform, runs in the AIR runtime and not in the browser, file IO, ...
I wouldn't pass over Flex/Air (Flash) without a closer consideration but here are a few others I have come across:
wxWidgets
GTK+
Qt
There is also a slashdot post with links to some tookits I haven't heard of. I'll add their recommendations here:
GLUI, an OpenGL-based GUI
Whisper, a Mac/Windows application framework
WxWindows, a framework which supports Windows 3.1/95/98/NT, and Unix with GTK/Motif/Lesstif, and MacOS
YAAF, Yet Another Application Framework, offering suport for Macintosh OS, Windows 95 and Windows NT, and X Windows
CPLAT, a framework for developing MacOS and Windows (Linux soon) applications
Ardi's Carbonless Copies technology, which is a portable rewrite of much of the MacOS API

I might suggest Mozilla XUL, but it has some drawbacks:
No really good development / debug environment (although there are tools and debuggers; they are variable)
You are locked into a vendor, but it is Mozilla.
It is very easy to use though and allows you to reuse your web Javascript skills for a rich-client app.
There's also Java of course. It satifies all your requirements AFAICS.
Plenty of custom charting controls, which are things you will struggle to find for GTK/WxWindows/$other_small_userbase_framework.
If you dont like Swing(its come a long way - Metal is dead, long live SystemDefault L&F!), there are options like SWT or even QT bindings for java(QTJambi).
For C or C++ go QT, its APIs are really nice.
For RCAs check out Eclipse RCP. For RIAs, you might be interested in OpenLaszlo. It's a rich internet platform that can compile both to Flash and DHTML.

I recently made a pretty complete list here: http://commadot.com/ria-frameworks/
ExtJS is probably my favorite and we use that at work. I think it satisfies your list. Otherwise, there are a bunch of other possibilities on that page.
