PyQt无边框以及移动问题

PyQt去边框以及移动问题

步骤

• 搭建基础PyQt架子

  from PyQt5.QtWidgets import QApplication, QWidget
  import sys
  
  class MainWiondw(QWidget):
      def __init__(self):
          super().__init__()
  
  if __name__ == "__main__":
      app = QApplication(sys.argv)
      w = MainWiondw()
      w.show()
      sys.exit(app.exec_())
  

• 设置去边框参数

  self.setWindowFlags(Qt.FramelessWindowHint)
  

• 重写鼠标按压、释放、移动事件

  def mousePressEvent(self, event):
      if event.button()==Qt.LeftButton:
          self.m_flag=True
          self.m_Position=event.globalPos()-self.pos()
          event.accept()
          self.setCursor(QCursor(Qt.OpenHandCursor))
  
  def mouseMoveEvent(self, QMouseEvent):
      if Qt.LeftButton and self.m_flag:  
          self.move(QMouseEvent.globalPos()-self.m_Position)
          QMouseEvent.accept()
  def mouseReleaseEvent(self, QMouseEvent):
      self.m_flag=False
      self.setCursor(QCursor(Qt.ArrowCursor))
