Changing the size of a Button

[K Viltersten]

How do i change the size of a Button
(using Tkinter), other than to set it
during construction?

I've found methods for getting the
size but not applying them.

I've been laborating with .setvar(*)
but i've been unsuccessful.

Hello Konrad,

How do i change the size of a Button
(using Tkinter), other than to set it
during construction?

In Tkinter, usually the geometry managers (such as pack) are the ones
who size the widgets.
If you run something like:
import Tkinter as tk

root = tk.Tk()
def change_size():
b["text"] = "More text"

b = tk.Button(root, text="Text", command=change_size)
b.pack()

root.mainloop()

You'll see that the button changes size to accommodate the new text.

HTH,

Thanks for the answer.

Unfortunately, that won't help me at all,
since i, apparently, asked the wrong
question. Let me refrain myself.

What i wish to do is to affect the size
of the button but not due to change of
text but due to resize of the frame it
resides in.

This far i've managed to get a callback
to a function as the resize occurs and to
print the sizes. However, i'd like to
assign these values to the button so it
always stays the same width as the frame.

Don't do it yourself, pack with the `fill` argument set to `Tkinter.X`.

This is done by the layout manager, too:

import Tkinter as tk

root = tk.Tk()
button = tk.Button(root, text="42")
button.pack(fill=tk.BOTH, expand=True)
root.mainloop()

Alternatively, with a grid layout:

button.grid(row=0, column=0, sticky="nsew")
root.rowconfigure(0, weight=1)
root.columnconfigure(0, weight=1)

Ah, great! I'll try that right away.
After breakfast, of course! Thanks!
