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()
