I have a QT widget app that I have been making for some time. I want to make GUI for it that looks rich and good. QT Design studio seems a good choice but I can't find resources to be sure that QT design studio GUI can be implemented to QT Widgets app.
Can I integrate UI from QT Design Studio to QT Widgets App (not QML app)?
I found a few links but they are not very clear. Can you help me answer this question, please?
No; Qt Design Studio generates QML, whereas Designer generates .ui files for widget applications.
I'm planning to build Web application and use the SignalR library to allow web admin to chat with other users (use Mobile application)
1- System admin uses Web Application built by Asp.net Boilerplate (.NET Core 3.1).
2- other users use Mobile Application built by (Qt Mobile application )
So, Is this scenario applicable with the SignalR library, or I will encounter some limitations especially with QT Mobile application?
Update:
Why I want this approach?
Because I'm using Esri QML SDK (in Mobile App)
I am not familiar with QT Mobile Application development, however I looked for it and understood that the language of development is C++.
Based on this, here is a client lib for SignalR in C++. You can use this lib to connect to c++
Click Here
Also, I wish to bring attention to an official documentation from Microsoft that states that C++ & Swift are unofficially supported framework.

I have not used SignalR before. However, Qt provides its own websocket QML client component as well as a server one, they have a client example here and a server example here should you want to see how the client component interacts.
I have used the QML websocket with a NodeJs websocket server and it presented no problems at all.
Creating a simple working environment should be no problem, Qt provides its own simulator with their IDE, just copy the client example, change the link to point to your server and give it a shot.
If you haven't got this up and running by now, I'll suggest you would take a look at signalr-qt. We have been using this for several years now, with Qt apps for iOS, Android and Windows desktop. Unfortunately it is not maintained anymore, but we've been running it in production apps using Qt 5.6, Qt 5.12 and Qt 5.15.
Is there a open source automation tool for Qt app? I'm looking for a automation tool for Qt app, Squish is too expensive
If you're OK with writing your tests in Selenium, you can try qtwebdriver
I have a window based application developed in Qt framework. When I try to automate it using UFT tool, the objects are not recognized. Does anyone know how to solve this issue?
I want to develop an Adobe air application. Whats the difference between using the Air SDK or Flex SDK and what are the advantages / disadvantages? My application will use a SQLlite database and PHP may be involved later if I turn the whole thing into a web app.
thanks
"If you want to develop an Air application, you must use the Air SDK. If you want to develop a Flex application that runs on Air, you need to use both." - #joshtnjala
I believe #joshtnjala to be partially correct, but I wanted to add on it. If using the Flex 3.3 SDK, you no longer require the AIR SDK as those tools are available to the Flex 3.3 SDK. It is important to note, because I see a lot of confusion or misuse of the term, Flex is actually three things.
Flex SDK (currently 3.3)
allows developers without the Flash and/or Flex IDE's, to develop and compile/publish Actionscript3 and MXML code to flash content (SWF). For example, one could use FlashDevelop for an IDE, and compile the code using the Flex 3.3 SDK.
Flex Framework
(From adobe [http://www.adobe.com/products/flex/overview/][1]) Flex is a free, open source framework for building highly interactive, expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. It provides a modern, standards-based language and programming model that supports common design patterns. MXML, a declarative XML-based language, is used to describe UI layout and behaviors, and ActionScript™ 3, a powerful object-oriented programming language, is used to create client logic. Flex also includes a rich component library with more than 100 proven, extensible UI components for creating rich Internet applications (RIAs), as well as an interactive Flex application debugger.
Flex Builder 3
Flex Builder is merely an IDE to assist in the development of flash (SWF), or AIR content. This builder utilizes the SDK above to compile. The framework may or may not be used depending on the developers needs. Many developers have taken themselves out of the FLASH IDE (THAT NASTY TIMELINE!) and began scripting their AS3 purely in the Flex Builder IDE as it provides many useful features for the "advanced" programmer; Not to mention its a very clean UI and is built on eclipse so it has many plugins and a solid community behind its architecture.
That being said, to expand on what joshtnala said, the difference between using the AIR SKD and the Flex 3.3 SDK, is that if you merely want to build an AIR app, composed of Actiosncript3 code, the AIR SDK is all you need (33mb unpacked). If you intend to use MXML and any part of the "Flex Framework" then you must use the Flex 3.3 SDK (190mb unpacked). This will allow you to use the many available components such as Datagrids, Accordions, etc, in your AIR application. So in the end, both will develop an AIR application as Flex 3.3 SDK incorporates the AIR 1.5 development tools. Abstract your project out, figure out what you will need, if a component works for that, or if a custom implementation is needed, etc, then choose your toolkit.
Hope this helps.
These frameworks are combinable. If you want your app to be both on the web and the desktop, make it using the Flex SDK, then wrap the desktop version of this using Air.
If you're considering deploying on the web, and communicating with a backend server and all that jazz, then flex is the way to go. If your target is desktop users, then AIR.
If you want to develop an Air application, you must use the Air SDK. If you want to develop a Flex application that runs on Air, you need to use both.
