QML 仿qq登录界面，准备 --- 无标题 + 圆角 + 可拖动窗口(1)

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts

Window {
    id: window
    width: 430
    height: 330
    visible: true
    title: qsTr("Positioner")
    flags: Qt.FramelessWindowHint | Qt.Window
    color: "#00000000"

    Rectangle{
        anchors.fill: parent
        color: "gray"
        radius: 2
        MouseArea {
            property point clickPos: "0,0"
            anchors.fill: parent
            acceptedButtons: Qt.LeftButton
            onPressed:(mouse)=>{
                clickPos  = Qt.point(mouse.x,mouse.y)
            }
            onPositionChanged:(mouse)=>{
                var delta = Qt.point(mouse.x-clickPos.x, mouse.y-clickPos.y)
                window.setX(window.x + delta.x)
                window.setY(window.y + delta.y)
            }
        }
    }
}

• window.flags中， Qt.Wiindow的作用是，让窗口在任务栏中有显示
• acceptedButtons: Qt.LeftButton,只接收左键
