# 无边框自定义标题栏窗口
|
|
|
|
|
|
|
|
|
|
|
|
### [Python3.4.4 or Python3.5][PyQt5]
|
|
|
|
|
|
|
|
|
|
|
|
原理说明:
|
|
|
|
|
|
|
|
|
|
|
|
- 使用一个QWidget（FramelessWindow）作为父窗口, 一个TitleBar作为标题栏, 一个QWidget作为底部容器
|
|
|
|
|
|
- 父窗口FramelessWindow设置为背景透明，但是需要绘制一定宽度的透明度很高的矩形边框用来接受鼠标事件（变形鼠标样式进行调整窗口大小）
|
|
|
|
|
|
- TitleBar的最小化最大化关闭等按钮事件关联到父窗口里
|
|
|
|
|
|
- TitleBar中的鼠标按下移动事件得到坐标也传递到父窗口调用move方法进行窗口移动
|
|
|
|
|
|
|
|
|
|
|
|
使用方法：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
class MainWindow(QWidget):
|
|
|
|
|
|
|
|
|
|
|
|
def __init__(self, *args, **kwargs):
|
|
|
|
|
|
super(MainWindow, self).__init__(*args, **kwargs)
|
|
|
|
|
|
layout = QVBoxLayout(self, spacing=0)
|
|
|
|
|
|
layout.setContentsMargins(0, 0, 0, 0)
|
|
|
|
|
|
layout.addWidget(QPushButton('按钮', self))
|
|
|
|
|
|
layout.addWidget(QTextEdit(self))
|
