python - AttributeError：“布尔”对象没有属性“按钮”

问题描述

当我尝试运行此代码时，我得到了错误：

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

在函数中，当我单击鼠标左键时，fillLabel如何从 QLabel 图像中获取位置 x，y （只要未单击鼠标右键来终止位置选择）？我可以使用 QCrusor，但位置值将来自整个 MainWindow，我只想要来自 QLabel 图像的位置。

这里使用的图像是这样的：

解决方案

  • 解决方案是这样的：首先我在类中添加了 x 和 y 变量，并将点击标签的事件 ov 连接到函数选择标签：
        self.x         = None
        self.y         = None 
        self.LB_Image_Orig.mousePressEvent = self.choseLabel
  • 然后将函数更改fillLabel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)
