1.文件作为模型

model:FolderListModel{
    id:folderModel;
    objectName: "folderModel";
    sortReversed:true
    sortField :FolderListModel.Name
    showDirs: true;
    showFiles: false;
    showDirsFirst: true;
    //nameFilters: [ "*.png", "*.jpg" ,"*.bmp","*.jpg","*.jpg"]
    folder:root.childFolder
    onFolderChanged: {
        view.currentIndex = -1;
    }
}

2.例子

ComboBox {
    id:timeComBox
    width:parent.width
    anchors.verticalCenter: timeLable.verticalCenter
    editable: false
    textRole: "fileName"        /* !这个是我找了大半天的方法,才发现这个关键字! */
    delegate:ItemDelegate {
        id:itemD
        width: timeComBox.width
        contentItem: Text {
            text: fileName
            color: "#21be2b"
            font: timeComBox.font
            elide: Text.ElideRight
            verticalAlignment: Text.AlignVCenter
        }
        highlighted: timeComBox.highlightedIndex === index
    }

    model:  FolderListModel {
        id: timeFolder
        showDirs: true;
        showFiles: false;
        folder:root.initFolder
    }

    onActivated:{
        /*! 刷新listview !*/
        root.parentFolder =root.initFolder + timeFolder.get(index, "fileName")+ "/"
    }

}
