Cannot get QML FolderListModel to work?

Diracsbracket

Hi.
I'm trying to get a list of .xml files in a folder using FolderListModel but when I use
folderModel.rowCount(), it always returns 0.

ApplicationWindow  {
    visible: true
    FolderListModel {
        id: folderModel
        //folder: "qrc:///qml/remotes"
        folder: "file:///" + applicationDirPath + "/remotes"
        nameFilters: ["*.xml"]
        showFiles: true
        showDirs: false
    }

    LauncherList {
        id: ll
        anchors.fill: parent

        Component.onCompleted: {
            console.debug(folderModel.rowCount())
            console.debug(folderModel.folder)
        }
    }
}

applicationDirPath is set in main.cpp:

QQmlApplicationEngine engine;
engine.rootContext()->setContextProperty("applicationDirPath", QGuiApplication::applicationDirPath());

The output of console.debug(folderModel.folder) shows the correct path, but folderModel.rowCount() always returns 0, so I must be doing something wrong?

Update: The model itself seems to work, only the rowCount() method or count properties don't seem to work?

@Diracsbracket
that is most likly the case, because FolderListModel has no function or property called rowCount
it has count

count : int

Returns the number of items in the current folder that match the filter criteria.

LauncherList seems to be a custom QML-Item, maby that one has rowCount property or function, and you confused them ?

@J.Hilk
thanks. I got the rowCount() from the Qt Creator's context help, but I agree it may not be usable in QML. Also, no errors are reported when I use it?. However, I also tried to use the count property, and that one also always returns 0. The ListView I use to test the FolderListModel however correctly shows the files....

@Diracsbracket mmh, on completed might be the wrong point in time to check the count property, try the following:

FolderListModel {
        id: folderModel
        folder: "file:///" + applicationDirPath + "/remotes"
        nameFilters: ["*.xml"]
        showFiles: true
        showDirs: false

        onCountChanged: console.log("Count Changed",count)
    }

@J.Hilk said in Cannot get QML FolderListModel to work?:

onCountChanged: console.log("Count Changed",count)

OK that works... I'm new to QML and the declarative paradigm and I'm affraid it will take a lot of time to get used to it... and to get even simple things to work.
