一个简单的实现使用 QFrame 的子类（这是您用作“标题栏”的东西）并实现鼠标事件以移动其顶层 window。

概念是获取鼠标按下事件的位置（帧的局部），计算鼠标移动事件的差异，并通过添加当前 window 位置和以上差异。

class DragWidget(QFrame):
    startPos = None
    def mousePressEvent(self, event):
        if event.button() == Qt.LeftButton:
            self.startPos = event.pos()

    def mouseMoveEvent(self, event):
        if event.buttons() == Qt.LeftButton and self.startPos is not None:
            delta = event.pos() - self.startPos
            self.window().move(self.window().pos() + delta)

    def mouseReleaseEvent(self, event):
        self.startPos = None


class YourWindow(QMainWindow):
    def Musteri_Ekle_Penceresi(self):
        # ...
        self.title_bar = DragWidget(self.drop_shadow_frame)
        # ...
