Python Tkinter - 设置输入网格宽度100%

Question

当我button + entry + button在网格中创建时,entry居中但不完全填充列.我如何通过填充列Entry？

# Python 3.4.1

import io
import requests
import tkinter as tk
from PIL import Image, ImageTk

def get_image():
    im = requests.get('http://lorempixel.com/' + str(random.randint(300, 400)) + '/' + str(random.randint(70, 120)) + '/')
    return Image.open(io.BytesIO(im.content))


class ImageSelect(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)

        master.resizable(width=False, height=False)
        master.title('Image manager')
        master.iconify = False
        master.deiconify = False
        master.grab_set = True

        image = ImageTk.PhotoImage(get_image())
        self.image = tk.Label(image=image)
        self.image.image = image
        self.image.grid(row=0, columnspan=3)


        self.reload = tk.Button(text='Reload').grid(row=1, column=0, sticky='w')
        self.path = tk.Entry().grid(row=1, column=1, sticky='we')
        self.submit = tk.Button(text='Submit').grid(row=1, column=2, sticky='e')

root = tk.Tk()
app = ImageSelect(master=root)
app.mainloop()

使用grid()你可以使用grid_columnconfigure()父母的Entry

import tkinter as tk

root = tk.Tk()

tk.Entry(root).grid(sticky='we')
root.grid_columnconfigure(0, weight=1)

root.mainloop()

使用pack()你可以使用fill='x'

import tkinter as tk

root = tk.Tk()

tk.Entry(root).pack(fill='x')

root.mainloop()

BTW:使用:

self.path = tk.Entry().grid()

您分配的结果grid()来self.path,但grid()总是返回None.

如果您需要,self.path那么:

self.path = tk.Entry()
self.path.grid()

如果你不需要self.path那么你可以这样做:

tk.Entry().path.grid()
