如何阻止 Tkinter 消息小部件调整大小？

Question

我正在创建三个“消息小部件”，但它们似乎根据内部内容调整宽度和高度的大小，是否可以防止这种情况？

from tkinter import *

root = Tk()
root.configure(background = 'Yellow')
root.geometry('500x400')

a = '{}'.format('The Elepthan is Big')
b = '{}'.format('The Bird')
c = '{}'.format('The Lion is big and ferocious, kills any animal')

msg = Message(root, text = a, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack()


msg = Message(root, text = b, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack()

msg = Message(root, text = c, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack()




root.mainloop()

更新：

您在这里有几个选项，但根据您的评论，widgets resize according to their content, I want them all with same width我将使用几何管理器给出最适合您需求的示例pack()。

对于 pack 至少最简单的选择是 pack(fill = BOTH)

完成您想要的操作的最快方法是使用框架。框架将调整为最大文本大小，并且在所有消息小部件上使用pack(fill = BOTH)会将较小的小部件扩展为框架的大小，这也是最大小部件的大小。

from tkinter import *

root = Tk()
root.configure(background = 'Yellow')
root.geometry('500x400')

a = '{}'.format('The Elepthan is Big')
b = '{}'.format('The Bird')
c = '{}'.format('The Lion is big and ferocious, kills any animal')

frame = Frame(root)
frame.pack()

msg = Message(frame, text = a, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack(fill=BOTH)


msg = Message(frame, text = b, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack(fill=BOTH)

msg = Message(frame, text = c, width=300, justify='left')
msg.config(bg='lightgreen',relief=RIDGE, font=('times', 9), pady=-2, borderwidth=3)
msg.pack(fill=BOTH)

root.mainloop()
