Problems Loading Mock Data with qmlscene

[dbrian]

I'm having some problems figuring out how the loading scheme works for 'dummy data' when prototyping with qmlscene. Hoping someone can help me out.

I have a pretty basic main qml file that expects a context property 'runtime'. This object has a sub property 'availableScanners', which is a list of QObject-derived pointers wrapped by a QQmlListProperty.

@
// main.qml
import QtQuick 2.2

Rectangle {
implicitHeight: 1280
implicitWidth: 1024

ListView {
    model: runtime.availableScanners
}

}
@

I'm trying to set up some dummy data so that I can tweak the front end without having to rely on a C++ backend every time I run. I've set up a 'dummydata' folder in the same directory as main.qml, containing two files: runtime.qml and MockScanner.qml. The files are defined as follows:

@
//runtime.qml
import QtQuick 2.0

QtObject {
id: model

property list<MockScanner> availableScanners: [
    MockScanner {
        serialNumber: "xxxxxx08"
        connectionState: "UnconnectedState"
    },
    MockScanner {
        serialNumber: "xxxxxx08"
        connectionState: "UnconnectedState"
    },
    MockScanner {
        serialNumber: "xxxxxx08"
        connectionState: "UnconnectedState"
    },
    MockScanner {
        serialNumber: "xxxxxxx08"
        connectionState: "UnconnectedState"
    }
]

Component.onCompleted: console.log('done: ', availableScanners[0].serialNumber);

}
@

@
//MockScanner.qml
import QtQuick 2.0

QtObject {
property string serialNumber: "SerialNo"
property string connectionState: "UnconnectedState"

Component.onCompleted: console.log('Created Mock')

}
@

When I try to run main.qml with qmlscene, the model will not load correctly and I get the following output:
@
Starting external tool 'qmlscene' (...)/Source/qml/main.qml
Created Mock
Loaded dummy data: "(...)/Source/qml/dummydata/MockScanner.qml"
QQmlComponent: Component is not ready
<Unknown File>: MockScanner is not a type
(...)/Source/qml/main.qml:263: ReferenceError: runtime is not defined
@

The weird thing is that if I run either "runtime.qml" or "MockScanner.qml" within qmlscene, everything works fine (no complaints about MockScanner not being a type).

Am I doing something wrong or unsupported? Or is this potentially a problem with the qmlscene loading mechanism for dummy data? Any insight would be greatly appreciated.

Thanks!

Hi,

How does your main.qml look like with the mock data?

Are you still using this:

@ // main.qml
import QtQuick 2.2

Rectangle {
    implicitHeight: 1280
    implicitWidth: 1024
 
    ListView {
        model: runtime.availableScanners
    }
}

@

if so, try renaming "runtime.qml" to "Runtime.qml" and change your mail.qml to this:

@import QtQuick 2.0
import Minh 1.0

Item {
width: 360
height: 360

Runtime {
    id: runtime
}

ListView {
    anchors.fill: parent
    model: runtime.availableScanners
    delegate: Rectangle {
        width: 60
        height: 60
        Text {
            anchors.fill: parent
            text: serialNumber
        }
    }
}

}@
