QML: How to remove invalid property name (M16)

Question

I have a basic QML library with a CPP class, a qrc file and a qml file:

CPP file:

qmlRegisterType( QUrl( "qrc:/MyType.qml" ), "LibA", 1, 0, "MyType" );

QRC file:

<RCC>
  <qresource prefix="/">
    <file>MyType.qml</file>
  </qresource>
</RCC>

QML file:

import QtQuick 2.0

Rectangle {
    color: 'blue'
    width: 50
    height: 50
}

When i use it in main.qml works fine but keep saying invalid property name "color" (M16) and its the same for "width" and "height". I know this can stay this way until works, but can be fixed?

Here my main.qml file:

import QtQuick 2.0
import QtQuick.Window 2.0

import LibA 1.0

Window {
    visible : true
    width: 640
    height: 480
    title: "Hello World"

    MyType {
        height: 100
        width: 100
        color: 'yellow'
    }
}

Im using Qt 5.14.2, Thanks in advance, sorry my bad english.

Is your main.qml not in the resource file? Why don't you import QtQuick 2.12 in the component as you do in other files? — folibis
The main.qml file its in a diferent qrc because its a application. The MyType.qml its in a library i put the same verson o qtquick and keep saying the same thing. — Siewdass Sf

I was faced with the same problem with the following code (main.qml):

import QtQuick 2.15
import QtQuick.Window 2.15
Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}

No error when building on Desktop Qt 5.15, but M16 errors for the properties width, height, visible and title when building for Android Qt 5.15

Then I used

ApplicationWindow

instead of

Window

This code works for Android:

import QtQuick 2.15
import QtQuick.Controls 2.15
ApplicationWindow {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}
