Error - when adding the qml file to the project.

Mathan M

Hi,

I just added an listportalitems.qml under the Resources/Qml.qrc/qml. When I try add in main.qml, The error was shown

qrc:/qml/main.qml:48 Cannot assign to non-existent property "listportalitems"

An Redline appears. I hover the redline the message shown as - "Invalid PropertyName listportalitems.qml" (M16)

How to get rid of this error?

Thanks in advance

A QML type can be defined either by a document in a .qml file beginning with a capital letter, or by a QObject-based C++ class.

Rename your file and make first letter capital. Then it will be identified as a QML component.

Thanks a lot p3c0,

It worked. I have an query.

it will be identified as a QML component.

Is any other way to call other.qml in main.qml. Ex: In my scenario, In my app, First I will be showing the Login page, once the user get authenticated, User can view the list of items available in the server.
I followed the below strategy, I created an Login.qml with user authentication code and I created ListPortalitem.qml to list the Portal Items.

In the main.qml I called the Login {} and ListPortalitem{}. Am I following the right approach?

Code Snippet: main.qml

import QtQuick 2.3
import QtQuick.Controls 1.2

ApplicationWindow {
    id: appWindow
    width: 800
    height: 600
    title: "MapsV1"

Login   {}
    
ListPortalitems {}

}//ApplicationWindow

Issue: How can I show the ListPortalitems.qml after the user is validated successfully, since validation part is taking part on the Login.QML.

Thanks in advance

@Mathan-M Yes your approach is correct.

Issue: How can I show the ListPortalitems.qml after the user is validated successfully, since validation part is taking part on the Login.QML.

To delay the initialization you can use following 2 ways:

Loader
createComponent and createQmlObject

Check out whichever is more suitable to your needs. I think Loader should suffice in your case.
