PyQt5实现仿QQ贴边隐藏功能的实例代码
作者：༺北海以北的等待༻꧂
这篇文章主要介绍了PyQt5实现仿QQ贴边隐藏功能,本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
此程序大致功能为：可变换颜色，贴边隐藏。
变换颜色思路
QPalette( [ˈpælət] 调色板)类相当于对话框或控件的调色板，它管理着控件或窗体的所有颜色信息，每个窗体或控件都包含一个QPalette对象，在显示时按照它的QPalette对象中对各部分各状态下的颜色的描述来进行绘制。
实现代码
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()
