Using custom objects in widget-based QML

[gkavrecic]

I have a Widget based application and one part is showing a QML file.
It works fine with built in types.

Want to load an external QML file (e.g. myScreen.qml) with custom QML objects.
Let's says there are two custom objects:

• BoxInResources (it shall be contained in the qml.qrc)
• BoxInFile (it shall be contained in a file named BoxInFile.qml)

The myScreen.qml shall look something like:

import QtQuick 2.7
import QtQuick.Controls 2.0

Rectangle {
    color: "green"
    Text { text: "TEST" }
    BoxInResources {}
    BoxInFile{}
}

First, I've tried with the BoxInResources. Added it in source files, qml.qrc, as QML. But nothing did the trick.
Each time at load it replies: BoxInResource is not a type

I also get the error if the file is in the working path.
How can I link it to the executable so it will be available as a type?

This is a rephrased question of https://forum.qt.io/topic/86789/using-a-qml-file-at-runtime

@gkavrecic
this is pretty well documented.
Please read this.

Thanks for that, but the link describes integrating C++ objects into QML.
This is the next step.

I would like to use QML objects. (hence the BoxInFile part)
I managed to add BoxInResource in a pure QML application.

I was more thinking of this approach.
But can't make it work.

So you can either import the folder containing your type/component directly from qrc within QML:

import "qrc:/path/containing/components"

If it's not working try: import ":/path/containing/components"

or alternatively:

// C++
qmlRegisterType(QUrl("qrc:///path/to/MyComponent.qml")), "MyTypes", 1, 0, "MyComponent");
...
// QML
import MyTypes 1.0
