Hi, I'm very new to plasma/qml. I'm trying to create a plasma DataEngine and a plasmoid that accesses to its data. The DataEngine is very simple: a source with a serie of QString as values. I tryed it in plasmaengineexplorer and it seems working fine. Then I passed to the plasmoid, very easy too: a simple Label to show one of the value stored in dataengine. I instantiated the dataSource this way:

Code: Select all

PlasmaCore.DataSource {
    id: dataSource
    engine: "myengine"
    interval: 30 * 60000;
    connectedSources: ["mySource"]
}

But I have a problem getting data from it. I'm using the following code:

Code: Select all

PlasmaComponents.Label {
    id: local;
    text: dataSource.data["mySource"]["myKey"];
}

But in console I have this error:

TypeError: Result of expression 'dataSource.data["mySource"]' [undefined] is not an object.

Can you explain my error?

Very thanks

If you don't get a response here, I suggest asking on #kde-devel or #plasma on Freenode, or on the plasma-devel@kde.org mailing list.
