圆角窗口
要实现圆角窗口，您需要做以下两件事
[En]
To achieve a fillet window, you need to do the following two things
- 设置窗口样式
透明背景self.setAttribute(Qt.WA_TranslucentBackground)# 无边框self.setWindowFlag(Qt.WindowType.FramelessWindowHint)# 通过 qss 设置背景和圆角self.setStyleSheet("Window{background-color:gray;border-radius:5px;}")
- 重载
​paintEvent​
opt = QStyleOption()opt.initFrom(self)p = QPainter(self)self.style().drawPrimitive(QStyle.PE_Widget, opt, p, self)super().paintEvent(event)
重载的目的是为了让窗口使用设置的QSS去绘制背景。
实现鼠标拖动
def mousePressEvent(self, event: PySide6.QtGui.QMouseEvent) -> None: if event.button() == Qt.LeftButton: self.mouse_start_pt = event.globalPosition().toPoint() self.window_pos = self.frameGeometry().topLeft() self.drag = Truedef mouseMoveEvent(self, event: PySide6.QtGui.QMouseEvent) -> None: if self.drag: distance = event.globalPosition().toPoint() - self.mouse_start_pt self.move(self.window_pos + distance)def mouseReleaseEvent(self, event: PySide6.QtGui.QMouseEvent) -> None: if event.button() == Qt.LeftButton: self.drag = False
