Question

我正在尝试实现简单的图像查看器，您可以从中选择2张图片。我有一个menubutton提供这些图片。选择其中一个图像后，程序会创建3个或5个按钮。我想在每个按钮上附加不同的图像，因此第一个按钮会有一个图像而第二个按钮会有另一个图像，依此类推。我用for循环创建了一个函数来创建这些按钮，但是从那一点开始无法继续。我可以将一个图像附加到所有图像上，但不能一个接一个地使用不同的图像。谢谢你的帮助

这是与您的问题相关的代码：

class Halabala():
    def __init__(self):
        .............
        self.pictures = ["pavuk1", "pavuk2", "pavuk3"]

        self.lists_labels = []
        self.lists_images = []

        self.init_image_list()
        ............

    def init_image_list(self):
        for i in self.pictures:
            picture = Image.open(i)
            picture.thumbnail((130, 130))
            self.lists_images.append(ImageTk.PhotoImage(picture))

    def create_labels(self, num):
        for label in self.lists_labels:
            label.destroy()
        self.lists_labels=[]

        for i in range(num):
            but = tk.Button(self.master, image = self.lists_images[i])
            but.grid(row = i + 1, column = 0)
            self.lists_labels.append(but)
