此程序大致功能为：可变换颜色，贴边隐藏。

变换颜色思路

QPalette( ["htmlcode">

def Painting(self):
 color = random.choice(["CCFFFF","CC6699","CC99FF","99CCFF"])
 palette1 = QPalette()
 palette1.setColor(self.backgroundRole(),
    QColor("#{}".format(color))) # 改变窗体颜色
 self.setPalette(palette1)

贴边隐藏思路

可以判断窗口的位置，当与边缘的距离小于某值时，再判断鼠标是否在窗口，判断是否隐藏窗口；
根据隐藏窗口的隐藏位置，获得某块区域，当鼠标在这个位置时，显示窗口。

实现代码

鼠标进入事件，调用hide_or_show判断是否该显示

def enterEvent(self, event):
 self.hide_or_show('show', event)

鼠标离开事件，调用hide_or_show判断是否该隐藏

def leaveEvent(self, event):
 self.hide_or_show('hide', event)

鼠标点击事件

def mousePressEvent(self, event):
 if event.button() == Qt.LeftButton:
  self.dragPosition = event.globalPos() - self.frameGeometry(
  ).topLeft()
  QApplication.postEvent(self, QEvent(174))
  event.accept()

捕捉鼠标移动事件

def mouseMoveEvent(self, event):
 if event.buttons() == Qt.LeftButton:
  try:
  self.move(event.globalPos() - self.dragPosition)
  event.accept()
  except:pass

判断是否该隐藏

def hide_or_show(self, mode, event):
 pos = self.frameGeometry().topLeft()
 if mode == 'show' and self.moved:
  if pos.x() + WINDOW_WEIGHT >= SCREEN_WEIGHT: # 右侧显示
  self.startAnimation(SCREEN_WEIGHT - WINDOW_WEIGHT + 2, pos.y())
  event.accept()
  self.moved = False
  elif pos.x() <= 0: # 左侧显示
  self.startAnimation(0,pos.y())
  event.accept()
  self.moved = False
  elif pos.y() <= 0: # 顶层显示
  self.startAnimation(pos.x(),0)
  event.accept()
  self.moved = False
 elif mode == 'hide':
  if pos.x() + WINDOW_WEIGHT >= SCREEN_WEIGHT: # 右侧隐藏
  self.startAnimation(SCREEN_WEIGHT - 2,pos.y())
  event.accept()
  self.moved = True
  elif pos.x() <= 2: # 左侧隐藏
  self.startAnimation(2 - WINDOW_WEIGHT,pos.y())
  event.accept()
  self.moved = True
  elif pos.y() <= 2: # 顶层隐藏
  self.startAnimation(pos.x(),2 - WINDOW_HEIGHT)
  event.accept()
  self.moved = True

将划入划出作为属性动画

def startAnimation(self,width,height):
 animation = QPropertyAnimation(self,b"geometry",self)
 startpos = self.geometry()
 animation.setDuration(200)
 newpos = QRect(width,height,startpos.width(),startpos.height())
 animation.setEndValue(newpos)
 animation.start()
