AttributeError：'bool'对象没有属性'button'

Question

[当我尝试运行此代码时，出现错误：

AttributeError: 'bool' object has no attribute 'button'

在函数fillLabel中，如何在单击鼠标左键时从QLabel图像中获得位置x，y]（只要<终止职位选择）？我可以使用QCrusor，但是位置值将来自整个MainWindow，我只希望位置来自QLabel图像。

这里使用的图像是这个：

解决方案是这样的：首先，我将x和y变量添加到类中，然后将事件ov单击标签上的连接到函数selectedLabel：

        self.x         = None
        self.y         = None 
        self.LB_Image_Orig.mousePressEvent = self.choseLabel

然后将功能fillLabel更改为：

    def fillLabel(self,event):
        if(self.label is not None):        
                if(self.x is not None):
                    y = round(self.y*(self.label.shape[1] / self.LB_Image_Orig.geometry().height()))
                    x = round(self.x*(self.label.shape[0] / self.LB_Image_Orig.geometry().width()))
                    print(x,y)
                    self.label[x,y] = self.comboBox.currentIndex()

位置选择功能：

    def choseLabel(self,event):
        if(self.image is not None):
            self.x = event.pos().x()
            self.y = event.pos().y()
            self.fillLabel(event)
