Can I run .qml files in CommandPrompt or PowerShell?

qazaq408

Forgive me ,i make a serious mistake.....it's .qml not .xml..

When i write a python,i can run this file(.py) by some IDE like "PY Charm",but i also can execute file(.py) in CommandPrompt or PowerShell like this

python E:/HelloWorld.py

So,if i write a QML file,like "E:/HelloQML.qml"

import QtQuick

Rectangle{
    width: 200
    height: 50

    Text{
        anchors.centerIn: parent
        text:qsTr("Hello QML")
    }
}

Can I execute "E:/HelloQML.qml" by CommandPrompt or PowerShell like

xxx E:/HelloQML.qml

@qazaq408 yes, if you have Qt installation in $PATH, you can run any QML file with:

qml E:/HelloWorld.qml

Start by reading The Whole Shebang - Running QML Files Directly. It's 10 years old, but often Qt stuff remains the same!

It looks like there should be an executable program qml.exe under Windows --- assuming it exists for that OS. However in any case note the author states

The usefulness of this tool is somewhat limited, because it only works for self-contained QML files and most real-world applications have some C++ code. However, it can be useful for applications such as tests and small demo programs. You might want to consider using it for small applications that you would have normally written as a shell script, but with QML (and JavaScript) can be done in a more portable way, as well as supporting a graphical user interface.

My post above was made before I saw yours. Does that author's admonition about the limited functionality this way still apply, so that the OP knows?

@JonB it does, yes. That tool won't help with QML files which expect some C++ backend.

@qazaq408 - Use can use qmlscene.exe (or qmlviewer.exe) for QML preview:

C:\Qt\6.1.2\msvc2019_64\bin\qmlscene.exe myfile.qml
