如何使用QML和PyQt5创建一个小型的无标题栏通知窗口

pip install pyqt5

import sys
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QGuiApplication
from PyQt5.QtQml import QQmlApplicationEngine

import QtQuick 2.0

Rectangle {
    id: root
    width: 400
    height: 100
    color: "lightblue"
    flags: Qt.ToolTip
    property string message: ""
    signal clicked()

    Text {
        anchors.centerIn: parent
        text: root.message
    }

    MouseArea {
        anchors.fill: parent
        onClicked: root.clicked()
    }
}

if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()

    # 加载QML文件
    engine.load("notification.qml")

    # 获取QML根对象并设置消息属性
    root = engine.rootObjects()[0]
    root.message = "这是一个通知窗口"

    sys.exit(app.exec_())
