Why there is no QtWebEngine in the Qt6? Is it depricated? Should I use a new widget?
Qt6 is a big change so for compatibility reasons Qt does not provide this module, it will be provided in Qt 6.2 as this post: Add-on support in Qt 6.0 and beyond points out.
For Qt 6.2 we are planning to provide the following additional
libraries:
Qt Bluetooth
Qt Data Visualization
Qt Lottie Animation
Qt Multimedia
Qt NFC
Qt Positioning
Qt Quick Dialogs: Folder, Message Box
Qt Remote Objects
Qt Sensors
Qt SerialBus
Qt SerialPort
Qt WebChannel
Qt WebEngine
Qt WebSockets
Qt WebView
(emphasis mine)
So you will have to wait for that release that according to what was announced will be available for September 2021

I have built a UI application using Qt 5.7 and an independent widget using Qt 4.8. The widget uses QGIS API, which is incompatible with Qt5. Is there a way to run the widget from the Qt5 based application?
It cant, the Binary Compatibility of Qt5 means that a library build with Qt 4.8 will not run on it. The Api Compatibility was mostly kept, so if you could compile the QGIS on Qt5, then you could run your application on it.
I have a manjaro Linux system. It comes preinstalled with a Qt designer software that has more widgets compared to default Qt creator. But I can only design GUI with this designer software. How would I write code for it?
I have Qt Creator 5.5 installed, but I don't know if it it possible to integrate these two and if yes, how?
As you can see from the picture it does not show Qt gui application option. What is that I am missing?
By the way it is Qt 5.2
It's the Qt Widgets Application that you are looking for. All Qt GUI applications use Widgets.
On the new Qt Creator 2.5.2, I no longer see the option to create a Mobile Qt Application when starting a New Project.
I'm on Ubuntu 12.10, and I installed Qt Creator from the repositories.
This is what I see on Qt Creator 2.4.1. This here is on Windows, but Mobile Qt Application used to be available on Ubuntu as well:
Those options appear in the Creator that comes bundled with Nokia's Qt SDK (and yes that contains an older version of Qt Creator and desktop and mobile Qt framework), you can download that from here
I have written a simple qt application with qt creator, I have tested with PC simulation and N900 device, It's OK. Qt Creator created a .deb file in my mobile. but it can't be installed. The installer always complained "incompatible package...".
The SDK document says I can modify my application's version, or I can skip the package step in the project setting, but in my Qt creator, there is no these setting at all.
Can anyone help me, thanks! :)
