QML Object Type is not a type error in QTCreator

Question

Hi Everyone i am new to QT and i am having trouble loading one qml through another qml Basically i have created a qml MyTabView(MyTabView.qml)

 import QtQuick 2.         


        

Answer 1

This error can also be caused by a component's having an error. For instance, I had this sequence of errors:

QQmlApplicationEngine failed to load component
qrc:/main.qml:6 Type MainView unavailable
qrc:/MainView.qml:27 Type ApplicationLocked unavailable
qrc:/ApplicationLocked.qml:4 MetaStateChart is not a type

It's not very clear, bu the error in MainView is caused by a problem in ApplicationLocked. When I fixed that error, everything else worked.

So contrary to the conventional wisdom of starting with the first compiler error, it may be necessary to start with the last one!

Answer 2

I had a similar problem.

qrc:AGview.qml:8:15: AGraph is not a type

I solved it: my original code (in my main.cpp):

view.setSource(QUrl("qrc:AGview.qml"));

the working one:

view.setSource(QUrl("qrc:/AGview.qml"));

I think without the slash it don't search in the actual folder.

Answer 3

Have you added the file to your Resources ?
Adding your MyTabView.qml to your project in the same directory of main.qml is not sufficient.
You have to put your QML file in the Resources (probably main.qrc/qml/) in order to have it deployed.
The editor of Qt Creator does not need this inclusion in order to find your type, therefore it displays no error.

Answer 4

You should rename your "TabView.qml" to something like "MyTabView.qml".

Because of that import

import "."

you have conflict of TabView from "QtQuick.Controls 1.2" and local folder "."
