第PyQt中實現(xiàn)自定義工具提示ToolTip的方法詳解self.label=QLabel(text,self)

self.ani=QPropertyAnimation(self,b'windowOpacity',self)

#setlayout

self.hBox.addWidget(self.label)

self.hBox.setContentsMargins(10,7,10,7)

#addshadow

self.shadowEffect=QGraphicsDropShadowEffect(self)

self.shadowEffect.setBlurRadius(32)

self.shadowEffect.setColor(QColor(0,0,0,60))

self.shadowEffect.setOffset(0,5)

self.setGraphicsEffect(self.shadowEffect)

self.timer.setSingleShot(True)

self.timer.timeout.connect(self.hide)

#setstyle

self.setAttribute(Qt.WA_StyledBackground)

self.setDarkTheme(False)

self.__setQss()

deftext(self):

returnself.__text

defsetText(self,text:str):

"""settextontooltip"""

self.__text=text

self.label.setText(text)

self.label.adjustSize()

self.adjustSize()

defduration(self):

returnself.__duration

defsetDuration(self,duration:int):

"""settooltipdurationinmilliseconds"""

self.__duration=abs(duration)

def__setQss(self):

"""setstylesheet"""

f=QFile("resource/tooltip.qss")

f.open(QFile.ReadOnly)

self.setStyleSheet(str(f.readAll(),encoding='utf-8'))

f.close()

self.label.adjustSize()

self.adjustSize()

defsetDarkTheme(self,dark=False):

"""setdarktheme"""

dark='true'ifdarkelse'false'

self.setProperty('dark',dark)

self.label.setProperty('dark',dark)

self.setStyle(QApplication.style())

defshowEvent(self,e):

self.timer.stop()

self.timer.start(self.__duration)

super().showEvent(e)

defhideEvent(self,e):

self.timer.stop()

super().hideEvent(e)

工具提示繼承自QFrame的原因是我們需要設(shè)置邊框樣式，樣式表如下所示，支持亮暗兩種主題：

ToolTip[dark="false"]{

border:1pxsolidrgba(0,0,0,0.06);

border-radius:5px;

background-color:rgb(243,243,243);

ToolTip[dark="true"]{

border:1pxsolidrgb(28,28,28);

border-radius:5px;

background-color:rgb(43,43,43);

QLabel{

background-color:transparent;

font:15px'SegoeUI','MicrosoftYaHei';

QLabel[dark="false"]{

color:black;

QLabel[dark="true"]{

color:white;

測試

下述代碼的運行效果就是動圖中所示的樣子，只要給想要設(shè)置工具提示的部件安裝上事件過濾器，就能將QToolTip替換成自定義的工具提示：
