I've got the following error upon trying to add QtQuick.Dialogs 1.(0/1/2) to my project:
qrc:/qml/main.qml:4 module "QtQuick.Dialogs" is not installed
Now here is the thing, if I create a completely new app (standard empty QtQuick application) and add this line and the file dialog example from QML FileDialog documentation, then there is no problem.
Any ideas on what the problem might be?
Solved it!! It turns out that the problem was that I had used windeployqt on the output folder. This conflicted with adding new qtquick components. The solution was to delete everything in the output folder and generate a clean compiled and it worked. In case it helps anyone else.

I am getting started with qt and especially qt quick now and wanted to do the example from here: https://doc.qt.io/qt-5/qtquick3d-simple-example.html
However already the line import QtQuick3D 1.15 has been giving me headaches. The error that is printed says QML Module not found (QtQuick3D). If I am trying to import other things, I get the corresponding errors.
The error message also tells me "for qmake projects use the QML_IMPORT_PATH variable to add import paths" however I don't know what path and how I should set this?
Another solution I have seen is the one suggested here: https://stackoverflow.com/a/64952178/13533641.
Again I am unsure which path to add here. I tried "/usr/lib/qt5/bin" and "/home/Qt/5.15.2/gcc_64/bin". After setting the value I restarted Qt Creator but the error remained.
The project I have been using is an empty QT Quick application which you get if you create a new project. I just added that one import line.
I have used the Mainainance Tools to check the plugins and I installed something that was named 3D. I am unsure if this is the "normal" qtwidget thing or the one I am trying to use in the code. (Or maybe there is no difference anyway, who knows)
I use qt version 5.15 right now but I also tried installing the 5.9 and 6. Everywhere I have the same problem.
My machine runs ubuntu 20.04 and I installed qt using the official download for linux.
If I am correct, it got installed in the directory /home/Qt.
Does anybody know how to solve this?
After trying different paths and versions of Qt, I found this this instruction here
However I only needed to follow until the picture of the mainaintance tool and not the building afterwards. Before I had already added the additional library for Qt3d. This enough wasn't enough apparently, after adding the Qt-shader tools it and conan it worked however.
I did this after yet another fresh installation of Qt (this time version 6) and it worked now.
Regarding the suggested change for the qml emulation layer: the path that is now set is /home/Qt/5.15.2/gcc_64/bin.
Hope this helps someone in the future!
Qt6 supports importing QML modules without specifying the version number.
Example:
Qt5: import QtQuick 2.0
Qt6: import QtQuick
where Qt6 will just choose the newest version of the module.
My problem is, that the current version of qtcreator does not seem to know about this feature (or any Qt6 features, most likely). I get the following error:
Opening the Designer with this error present, results in an error message telling me, that the QML code is broken. Running the project works flawlessly. I work on Arch Linux and installed the whole qt6 group as well as pyside6 and the install was successful. I tried to add Qt6 functionality by choosing /usr/bin/qmake-qt6 under Tools > Options > Kits > Qt Versions > Add, but this did not change anything, which does not seem surprising to me, but I thought I would try.
Is anyone else facing this problem? Have I overseen something? Can I maybe select another QML linter in an option I did not see?
Any help will be very much appreciated, I will continue to work with hardcoded version numbers for now, but I really like this new feature.
When I first run this option in first picture, I get the error in second picture.
However, if I create a new project with current project's files, this option is working well. I don't know why this happens. Can anyone help me solve this? Thank you so much.
I have search much solutions, but neither did them work for my situation.

How to make QtLinguist shipped with Qt 5.9.1 work?
I have fix this problem. Our project list contains one item that its related local file is deleted by others, and I just remove this item. Now everything just be fine. The .tf file is now can produced by Qt tool.
How can I import these code examples into QT Creator 3.4.0 ? I tried the available import options but they don't work.
I tried to create an empty QML project and add the rectangle.qml file to it. When I tried to run it, nothing showed up.
The book examples contain files .qmlproject - which seems to be a project descriptor. I wonder if it is somehow possible to import these .qmlproject files into QT Creator, click and run the examples.
I think this link might help in finding the solution : https://forum.qt.io/topic/27525/what-is-qmlproject-file/3 .
Usually I'd say that you should go to File > Open File or Project... and select the .qmlproject and you're done, but support for this type of project file was disabled by default. If you try to do this now (I believe the change is in Creator 3.4), you'll just get an error message about Creator not supporting the mime type of the file, or something. Unfortunately, this is not a very useful error message for a beginner, and it won't tell you how to fix the problem.
If you want to use .qmlproject files in newer versions of Creator, you have to navigate to Help > About Plugins... and enable the QmlProjectManager plugin (it's under the Qt Quick section) by checking the box.
So this is how you should normally open project files in Qt Creator. As for the window not showing up, that's also commonly encountered and can be fixed by making the root item in your scene a Window:
Unlike QQuickView, QQmlApplicationEngine does not automatically create a root window. If you are using visual items from Qt Quick, you will need to place them inside of a Window.
Qt Creator's new project wizard handles this for you when you create a new Qt Quick project, as you saw when you got the "Hello World" window to open in your video. It was when you loaded concepts/rectangle.qml which had a Rectangle as its root item, that it stopped showing up. That QML file was likely used in a project where a QQuickView was displaying it.
I'm trying to import a Qt Quick-Application project from a colleague of mine into my QtCreator installation. Both QtCreator versions are exactly the same.
When I am opening the .pro file I get the message that the .user file could not be found, although it is in the same folder.
When I click on proceed I am getting a default project imported but not all the files of the project which are present and should be recognized.
Also trying to add the remaining data through the option from the right-mouse-click menu does not have any effect.
Anyone here to give me a hint?
