QML component unable to find other QML components

mjohn

Hello,

I'm new to QML and have been working through the guides. Originally I had my qml files in the top project directory and all was good. From C++ I was able to load the main.qml file like so:

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

And in the qmake file:

RESOURCES += qml.qrc

I stumbled upon the 'Best Practices' guide and moved all my QML files to a 'qml' directory. I've updated the paths in the .qrc file and C++ like so:

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/qml/main.qml")));

Now when I try to run my project I get the following error:

QML debugging is enabled. Only use this in a safe environment.
QQmlApplicationEngine failed to load component
qrc:/qml/main.qml:149 Type LockedScreen unavailable

Since the 'LockedScreen' QML component is now in the qml directory it seems other QML components cannot find it.

Here is like 149 from 'main.qml':

initialItem: LockedScreen { }

How can I get this to work? I have 'LockedScreen.qml' as its own file in the qml directory.

Thanks.

@mjohn
maybe a stupid question, but did you also add the LockedScreen component also qrc file?
If so please post the qrc contents

Here is my qrc file. It does include the LockedScreen component.

<RCC>
    <qresource prefix="/">
        <file>qml/main.qml</file>
        <file>qml/AuthenticationUserPin.qml</file>
        <file>qml/CommandBar.qml</file>
        <file>qml/Home.qml</file>
        <file>qml/LockedScreen.qml</file>
        <file>qml/NumericKeypad.qml</file>
    </qresource>
</RCC>

@mjohn
question,
did you make a complete clean rebuild yet?

deleting buildfolder, running qmake, than build&run

after messing with your qrc file you should do that, so no other remnands from the last build remain

I've ran a 'clean all' and tried again. It still builds fine, the error occurs when I try to run.
