pyqt實現視窗邊框陰影製作效果(python)__python

參考QT例子，做下記錄：

思路：

1.準備圖片

2.設定邊框顯示寬度

 self.SHADOW_WIDTH=8

3. 實現方法

def drawShadow(self,painter):        #繪製左上方、左下角、右上方、右下角、上、下、左、右邊框        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]))   #左上方        painter.drawPixmap(self.width()-self.SHADOW_WIDTH, 0, self.SHADOW_WIDTH, self.SHADOW_WIDTH, QPixmap(self.pixmaps[2]))   #右上方        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

4.繪圖

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))

寫一個類,後面只要繼承這個類就可以了, 記得去掉標題列和設定背景透明：

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

效果如下：
