在python中,我尝试更改tkinter消息框窗口的宽度,以使文本可以放在一行上。
import tkinter as tk
from tkinter import messagebox
root = tk.Tk()
messagebox.showinfo("info","this information goes beyond the width of the messagebox")
root.mainloop()

@CharleyPathak是正确的。您可能需要在文本中间添加换行符,因为消息框可以显示多行,也可以创建一个自定义对话框。

我设法拥有适合自己的尺寸 “ tkMessageBox.showinfo(title =” Help“,message = str(readme))” :
我想显示一个帮助文件(readme.txt)。
def helpfile(filetype):
if filetype==1:
with open("readme.txt") as f:
readme = f.read()
tkMessageBox.showinfo(title="Help", message = str(readme))
我打开了文件readme.txt并对其进行了编辑,以便所有行的长度不超过65个字符。那对我来说很好。我认为不要在其中包含CR / LF的长行很重要。因此,请正确格式化txt文件。

这是另一种获得您正在寻找的效果但不使用消息框的方法。它看起来更长,但它在定制方面提供了更多。
def popupmsg():
popup = tk.Tk()
def leavemini():
popup.destroy()
popup.wm_title("Coming Soon")
popup.wm_attributes('-topmost', True) # keeps popup above everything until closed.
popup.wm_attributes("-fullscreen", True) # I chose to make mine fullscreen with transparent effects.
popup.configure(background='#4a4a4a') # this is outter background colour
popup.wm_attributes("-alpha", 0.95) # level of transparency
popup.config(bd=2, relief=FLAT) # tk style
# this next label (tk.button) is the text field holding your message. i put it in a tk.button so the sizing matched the "close" button
# also want to note that my button is very big due to it being used on a touch screen application.
label = tk.Button(popup, text="""PUT MESSAGE HERE""", background="#3e3e3e", font=headerfont,
width=30, height=11, relief=FLAT, state=DISABLED, disabledforeground="#3dcc8e")
label.pack(pady=18)
close_button = tk.Button(popup, text="Close", font=headerfont, command=leavemini, width=30, height=6,
background="#4a4a4a", relief=GROOVE, activebackground="#323232", foreground="#3dcc8e",
activeforeground="#0f8954")
close_button.pack()
