Tkinter聊天机器人设计

Question

我正在学习Python和Tkinter。我正在尝试设计一个聊天机器人。我添加了工作的最终版本。我需要一些帮助。键入多行时，气泡将从窗口移出。如何将气泡保留在窗口中？如何在长文本中使气泡之间的距离保持恒定？对不起，我的英语不好。谢谢。

您可以在anchor方法中指定create_window。

class BotBubble:
    def __init__(self,master,message=""):
        self.master = master
        self.frame = Frame(master,bg="light green")
        self.i = self.master.create_window(70,490,window=self.frame,anchor="w")
        ...
