這篇文章主要介紹了PyQt5實(shí)現(xiàn)仿QQ貼邊隱藏功能,本文通過實(shí)例代碼給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

此程序大致功能為：可變換顏色，貼邊隱藏。

變換顏色思路

QPalette( [ˈpælət] 調(diào)色板)類相當(dāng)于對話框或控件的調(diào)色板，它管理著控件或窗體的所有顏色信息，每個窗體或控件都包含一個QPalette對象，在顯示時按照它的QPalette對象中對各部分各狀態(tài)下的顏色的描述來進(jìn)行繪制。

實(shí)現(xiàn)代碼

def Painting(self):
 color = random.choice(["CCFFFF","CC6699","CC99FF","99CCFF"])
 palette1 = QPalette()
 palette1.setColor(self.backgroundRole(),
    QColor("#{}".format(color))) # 改變窗體顏色
 self.setPalette(palette1)

貼邊隱藏思路

可以判斷窗口的位置，當(dāng)與邊緣的距離小于某值時，再判斷鼠標(biāo)是否在窗口，判斷是否隱藏窗口；
根據(jù)隱藏窗口的隱藏位置，獲得某塊區(qū)域，當(dāng)鼠標(biāo)在這個位置時，顯示窗口。

實(shí)現(xiàn)代碼

鼠標(biāo)進(jìn)入事件，調(diào)用hide_or_show判斷是否該顯示

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

鼠標(biāo)離開事件，調(diào)用hide_or_show判斷是否該隱藏

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

鼠標(biāo)點(diǎn)擊事件

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

捕捉鼠標(biāo)移動事件

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

判斷是否該隱藏

def hide_or_show(self, mode, event):
 pos = self.frameGeometry().topLeft()
 if mode == 'show' and self.moved:
  if pos.x() + WINDOW_WEIGHT >= SCREEN_WEIGHT: # 右側(cè)顯示
  self.startAnimation(SCREEN_WEIGHT - WINDOW_WEIGHT + 2, pos.y())
  event.accept()
  self.moved = False
  elif pos.x() <= 0: # 左側(cè)顯示
  self.startAnimation(0,pos.y())
  event.accept()
  self.moved = False
  elif pos.y() <= 0: # 頂層顯示
  self.startAnimation(pos.x(),0)
  event.accept()
  self.moved = False
 elif mode == 'hide':
  if pos.x() + WINDOW_WEIGHT >= SCREEN_WEIGHT: # 右側(cè)隱藏
  self.startAnimation(SCREEN_WEIGHT - 2,pos.y())
  event.accept()
  self.moved = True
  elif pos.x() <= 2: # 左側(cè)隱藏
  self.startAnimation(2 - WINDOW_WEIGHT,pos.y())
  event.accept()
  self.moved = True
  elif pos.y() <= 2: # 頂層隱藏
  self.startAnimation(pos.x(),2 - WINDOW_HEIGHT)
  event.accept()
  self.moved = True

將劃入劃出作為屬性動畫

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()
