Question

我正在尝试实现我的简单图像查看器，其中我有一个主要标签和menubutton有三个选择。每个按钮都会创建不同数量的按钮，里面有图片。我想创建一个主标签，然后用按钮上的图像更新其图像。因此，当我单击带图像的第一个按钮时，该图像将出现在标签上，然后单击第二个按钮，将出现第二个图像，依此类推。我试图创建两个函数，一个用于创建标签并更新其图像，另一个用于获取按钮上的当前图像，但我无法正确执行第二个。感谢您的帮助。这是代码：

    #def get_image(self):
    # don't know how to get current image from button

myapp = Halabala()
