## 18、无边框圆角对话框

[运行 FramelessDialog.py](FramelessDialog.py)
|

|

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
|
||||
2. 在QDialog中放置一个QWidget作为背景和圆角

3. 在QWidget中放置其他内容

## 19、调整窗口显示边框
|
||||
[运行 ShowFrameWhenDrag.py](ShowFrameWhenDrag.py)
|
||||
|
||||
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】
|
||||
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
|
||||
3. 必须先要替换wndproc为自己的函数
|
||||
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
|
||||
|
||||
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)
