How to refresh FolderListModel?

[mismail]

hello everybody,

Is there any way to refresh the FolderListModel so the view is able to display the new files added.

Thank you

You mean when files are added in the folder, then the FolderListModel should automatically update the model?

Or manually refresh the FolderListModel?

there is no deference I need the view to feel that something is added, whether this done manually or automatically.

I know this is an old thread but I searched for a long time to find an answer to this. The following worked for me, without this, when a file was added/deleted the list view was not updated properly (unless I exited and reopened the application).

@import QtQuick 1.1
import Qt.labs.folderlistmodel 1.0

ListView {
id: view
model: folderModel
delegate: Text { text: fileName }

property variant folderModel
function updateModel() {
    var folder = ""
    if (folderModel) {
        folder = folderModel.folder
        folderModel.destroy()
    }
    folderModel = modelComponent.createObject(view, {"folder": folder})
}

Component {
    id: modelComponent
    FolderListModel {}
}

Component.onCompleted: updateModel()

}

Looks like FolderListModel update the list automatically once new files are added or remove from path:(Qt5.7.1)

        ListView
        {
            id:myListViewUSB
            anchors.fill: parent

            FolderListModel
            {
                id: folderModelUSB
                folder: "file:///mnt/usb"
            }
            model: folderModelUSB

            delegate:
            Text
            {
                text:  fileName
                anchors.horizontalCenter: parent.horizontalCenter
            }
        }
