1. 通过设置 `self.setWindowFlags(self.windowFlags() | Qt.FramelessWindowHint)` 和 `self.setAttribute(Qt.WA_TranslucentBackground, True)` 达到无边框和背景透明
183+
2. 在QDialog中放置一个QWidget作为背景和圆角

[运行 ShowFrameWhenDrag.py](ShowFrameWhenDrag.py)
190+
191+
1. 全局设置是【】在控制面板中->调整Windows的外观和性能->去掉勾选 拖动时显示窗口内容】
192+
2. 但是为了不影响其它应用,可以在窗口处理函数wndproc中对其进行判断处理
193+
3. 必须先要替换wndproc为自己的函数
194+
4. 当消息事件==WM_NCLBUTTONDOWN的时候, 先强制开启，然后处理完成后再还原
195+
196+
好处在于可以减少窗口更新的次数（用途有频繁渲染的界面）
