QQmlApplicationEngine failed to load component

I use Qt in VS 2017 widows 10. here is code

and here is the error

what is the problem?

The code you're showing does not contain any errors.

Loading of main.qml fails at runtime, which suggests that:

• QRC file was not compiled
• QRC file was not included in the compiled binary
• main.qml is not in the QRC file

@sierdzio can you explain more, please?

[sierdzio]

But what should I explain?

I see you are using Visual Studio, so your setup is probably unusual. I do not know what build system you are using (qmake, cmake, something else?). I do not know if you are using QRC file at all (are you?). I have not seen the code of your QRC file, nor your build system files (*.pro or CMakeLists.txt). I can't guess all that.

@sierdzio I add .qrc and .qml file to my project. but I think this address "qrc:/main.qml" can not be found, why?

[sierdzio]

Because it's either wrong (do you have main.qml file? Is it added to QRC? Is the path and QRC syntax correct?) or the resource file is not properly added / linked into the binary.

Since you have still not shown any code, I can only keep guessing.

@sierdzio here is my resource

[sierdzio]

See the "Resource URL" field: this is what you need to paste into your source code.

So it's:

engine.load(QUrl("qrc:/qrc/mian.qml"));

Notice it's mian and and not main - you've made a typo.

BTW. In the future, please paste code, not pictures. This way I can copy-paste and tweak your stuff to help you, instead of typing everything myself.
