基于 QML 的 Qt 文件浏览器 [英] Qt File Browser based on QML

问题描述

使用 QFileSystemModel 很容易实现文件浏览器.但是listview UI 并不漂亮.所以我想用QML实现一个文件浏览器.QML 具有模型/视图支持.但是如何在 QML 中显示文件系统树呢?任何线索将不胜感激.

It is easy to implement a file browser by using QFileSystemModel. But the listview UI is not pretty. So I want to implement a file browser using QML. the QML has model/view support. But how to display the filesystem tree in QML? Any clue would be appreciated.

推荐答案

从Qt5.5开始我们有了TreeView QML组件，

Since Qt5.5 we have TreeView QML component available,

main.qml:

import QtQuick.Controls 1.4
TreeView {
    anchors.fill: parent
    TableViewColumn {
        title: "Name"
        role: "fileName"
        width: 300
    }
    model: my_model
}

main.cpp:

QFileSystemModel model;
model.setRootPath("/");
QQmlApplicationEngine engine;
engine.rootContext()->setContextProperty("my_model", &model);
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
