==================================================================
项目思路分析：
==================================================================
架构比较简单，但是使用Qt Quick来写的， 柑橘语法有点像CSS。
==================================================================
项目主要源码部分：
==================================================================
import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
ApplicationWindow{
id:im_Login
visible: true
width: 430 //483
height: 330 //458
title: qsTr("QQ登录界面")
flags:Qt.FramelessWindowHint //添加了这一句 隐藏了标题栏
MouseArea{ //设置可以拖动没有标题的登录界面. /*这个要放在上面，放在最下面的话，会把上面全部屏蔽掉的*/
anchors.fill:parent
property point clickPos: "0,0" //定义一个点
onPressed: {
clickPos = Qt.point(mouseX, mouseY)
winMenu.visible = false
}
onPositionChanged: { //属性的改变
var delta = Qt.point(mouseX-clickPos.x, mouseY-clickPos.y)
im_Login.setX(im_Login.x+delta.x)
im_Login.setY(im_Login.y+delta.y)

其中有些代码是重复的，只是一些参数不一样，但是不知道在.qml文件里面，该怎么重用这些代码，还是需要加油，继续学习
