大佬们，有办法pyqt5如何点击按钮控制窗口移动

qianaonan · 发表于 2023-4-24 15:58

我这边用透明无边框窗口设定了一个窗口，但是运行后发现无法移动窗口，所以我在窗口上排了一个按钮尝试通过按钮来移动窗口。虽然通过窗口move函数移动窗口，但是这也是临时解决问题。

这个需求我也有，以前研究了两天都没实现。

透明窗口要移动的话得重写鼠标的事件函数，比如：

[Python] 纯文本查看 复制代码

mousePressEvent (self, event) ： 鼠标键按下时调用;
mouseReleaseEvent (self, event) ： 鼠标键松开时调用;
mouseDoubieCiickEvent (self, event) - 双击鼠标时调用。

[Python] 纯文本查看 复制代码

    def mousePressEvent(self, e):
        self.__dragWin = True
        self.__dragWin_x = e.x()
        self.__dragWin_y = e.y()

    def mouseMoveEvent(self, e):
        if self.__dragWin == True:
            pos = e.globalPos()
            self.move(pos.x()-self.__dragWin_x,pos.y()-self.__dragWin_y-29)

你需要的是这个吗?

有大佬写好的无边框鼠标移动和双击全屏等都是一行 import就可以

重写 QWidget 的 mousePressEvent、mouseReleaseEvent 和 mouseMoveEvent 方法可以实现拖动无边框窗口
例如
class MyWindow(QtWidgets.QWidget):
def __init__(self):
      super().__init__()
      self.setWindowFlags(QtCore.Qt.FramelessWindowHint)
      self.setCursor(QtCore.Qt.SizeAllCursor)
      self.__press_pos = None

def mousePressEvent(self, event: QtGui.QMouseEvent):
      if event.button() == QtCore.Qt.LeftButton:
         self.__press_pos = event.pos()

def mouseReleaseEvent(self, event: QtGui.QMouseEvent):
      if event.button() == QtCore.Qt.LeftButton:
         self.__press_pos = None

def mouseMoveEvent(self, event: QtGui.QMouseEvent):
      if self.__press_pos is not None:
         self.move(self.pos() + event.pos() - self.__press_pos)
