tkinter.Toplevel大小自动适合其小部件

Question

I have made my custom infobox class, InfoBox , that I am using in my application. The tk.messagebox.showinfo did not suit my needs to the poor shape. But InfoBox does not adjust its size to fit the widgets I place inside. How can I make it as small as possible without cutting the widgets?

The class receives a string, msg , and a PhotoImage object, image , which are placed in the InfoBox. I added a screenshot of one such InfoBox.

class InfoBox(tk.Toplevel):
    def __init__(self, parent, msg, image):
        tk.Toplevel.__init__(self, parent)
        self.parent = parent
        self.msg = msg
        self.image = image

        self.title = "Gassy"
        self.font = font.Font(family="Optima", size=20)

        frame_left = tk.Frame(self)
        frame_right = tk.Frame(self)
        frame_left.grid(row=0, column=0, sticky=tk.NSEW)
        frame_right.grid(row=0, column=1, sticky=tk.NSEW)

        tk.Label(frame_left, image=self.image).grid(row=0, column=0, sticky=tk.N)

        textbox = tk.Text(frame_right, font=self.font)
        textbox.grid(row=0, column=0)
        textbox.insert(tk.END, self.msg)
        textbox.config(state=tk.DISABLED)

        tk.Button(frame_left, text="Den er grei!", font=self.font, command=self.destroy).grid(row=1, column=0)

As @kevin mentioned, it works as intended, the textwidget is mostly empty and occupies a large blank area, this is what makes you think that the geometry manager is not shrinking the window to the widgets.

this:

(I removed the images and fonts that were not provided, and unnecessary)

import tkinter as tk

class InfoBox(tk.Toplevel):
    def __init__(self, parent, msg):
        tk.Toplevel.__init__(self, parent)
        self.parent = parent
        self.msg = msg

        self.title = "Gassy"

        frame_left = tk.Frame(self)
        frame_right = tk.Frame(self)
        frame_left.grid(row=0, column=0, sticky=tk.NSEW)
        frame_right.grid(row=0, column=1, sticky=tk.NSEW)

#         textbox = tk.Text(frame_right) 
#         textbox.grid(row=0, column=0)
#         textbox.insert(tk.END, self.msg)
#         textbox.config(state=tk.DISABLED)

        tk.Button(frame_left, text="Den er grei!", command=self.destroy).grid(row=1, column=0)

root = tk.Tk()
info = InfoBox(root, '123 ' * 1000)
root.mainloop()

produces that:

whereas that:

import tkinter as tk

class InfoBox(tk.Toplevel):
    def __init__(self, parent, msg):
        tk.Toplevel.__init__(self, parent)
        self.parent = parent
        self.msg = msg

        self.title = "Gassy"

        frame_left = tk.Frame(self)
        frame_right = tk.Frame(self)
        frame_left.grid(row=0, column=0, sticky=tk.NSEW)
        frame_right.grid(row=0, column=1, sticky=tk.NSEW)

        textbox = tk.Text(frame_right) 
        textbox.grid(row=0, column=0)
        textbox.insert(tk.END, self.msg)
        textbox.config(state=tk.DISABLED)

        tk.Button(frame_left, text="Den er grei!", command=self.destroy).grid(row=1, column=0)

root = tk.Tk()
info = InfoBox(root, '123 ' * 1000)
root.mainloop()

produces this:

Clearly, the Toplevel subclass adjusts its size to the widgets it contains

The test widget is displayed at a certain size, regardless of its content. The Toplevel resizes around the widgets, NOT around whatever is inserted in the text widget; like with a text processor rudimentary window, the text processor does not shrink or expand as text is typed or edited. The same applies here.
The keyword args width and height allow to configure the size (as a number of characters, or lines) of a text widget
