PyQt6.5无边框窗口移动

百度搜了大部分都是pyqt5的。或者6.2 6.0版本的，下面演示demo

from PyQt6.QtCore import Qt, QPointF, QPoint
from PyQt6.QtWidgets import QApplication, QMainWindow, QWidget

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # 设置窗口无边框
        self.setWindowFlags(Qt.WindowType.FramelessWindowHint)

        # 创建一个子窗口
        self.widget = QWidget(self)
        self.widget.setGeometry(0, 0, 200, 200)

        # 设置子窗口背景颜色
        self.widget.setStyleSheet("background-color: red;")

        # 记录鼠标按下时的坐标
        self.mouse_pos = None

    def mousePressEvent(self, event):
        # 鼠标按下时记录坐标
        self.mouse_pos = event.globalPosition()

    def mouseMoveEvent(self, event):
        # 鼠标移动时计算移动距离
        if self.mouse_pos:
            diff = event.globalPosition() - self.mouse_pos
            self.move(self.pos() + diff.toPoint())
            self.mouse_pos = event.globalPosition()

    def mouseReleaseEvent(self, event):
        # 鼠标释放时清空坐标
        self.mouse_pos = None

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec()
