推荐答案

如果这是一个选择，我会抢QtQuick 2.0实现并使用它。它会自动反应到文件夹中的变化。

If it is an option for you, I'd grab the QtQuick 2.0 implementation and use that instead. It will automatically react to changes in the folder.

否则，你将别无选择，只能重新创建模型，例如

Otherwise, you'll have little choice but to recreate the model, e.g.

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()
}

丑陋，但它的作品。

Ugly, but it works.
