pyqt实现窗口边框阴影效果(python)_python 窗口 第三方库 阴影

参考QT例子，做下记录：

思路：

1.准备图片

2.设置边框显示宽度

 self.SHADOW_WIDTH=8

def drawShadow(self,painter):
        #绘制左上角、左下角、右上角、右下角、上、下、左、右边框
        self.pixmaps=QStringList()
        self.pixmaps.append(QString("./img/border/left_top.png"))
        self.pixmaps.append(QString("./img/border/left_bottom.png"))
        self.pixmaps.append(QString("./img/border/right_top.png"))
        self.pixmaps.append(QString("./img/border/right_bottom.png"))
        self.pixmaps.append(QString("./img/border/top_mid.png"))
        self.pixmaps.append(QString("./img/border/bottom_mid.png"))
        self.pixmaps.append(QString("./img/border/left_mid.png"))
        self.pixmaps.append(QString("./img/border/right_mid.png"))
        painter.drawPixmap(0, 0, self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[0]))   #左上角
        painter.drawPixmap(self.width()-self.SHADOW_WIDTH, 0, self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[2]))   #右上角
        painter.drawPixmap(0,self.height()-self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[1]))   #左下角
        painter.drawPixmap(self.width()-self.SHADOW_WIDTH, self.height()-self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[3]))  #右下角
        painter.drawPixmap(0, self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.height()-2*self.SHADOW_WIDTH, QPixmap(self.pixmaps[6]).scaled(self.SHADOW_WIDTH, self.height()-2*self.SHADOW_WIDTH)) #左
        painter.drawPixmap(self.width()-self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.height()-2*self.SHADOW_WIDTH, QPixmap(self.pixmaps[7]).scaled(self.SHADOW_WIDTH, self.height()- 2*self.SHADOW_WIDTH)) #右
        painter.drawPixmap(self.SHADOW_WIDTH, 0, self.width()-2*self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[4]).scaled(self.width()-2*self.SHADOW_WIDTH, self.SHADOW_WIDTH)) #上
        painter.drawPixmap(self.SHADOW_WIDTH, self.height()-self.SHADOW_WIDTH, self.width()-2*self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[5]).scaled(self.width()-2*self.SHADOW_WIDTH, self.SHADOW_WIDTH))   #下

def paintEvent(self, event):
        painter = QPainter(self)
        self.drawShadow(painter)
        painter.setPen(Qt.NoPen)
        painter.setBrush(Qt.white)
        painter.drawRect(QRect(self.SHADOW_WIDTH, self.SHADOW_WIDTH, self.width()-2*self.SHADOW_WIDTH, self.height()-2*self.SHADOW_WIDTH))

self.setWindowFlags(Qt.FramelessWindowHint)
self.setAttribute(Qt.WA_TranslucentBackground)

效果如下：
