Python Tkinter - 设置条目网格宽度 100% [英] Python Tkinter - Set Entry grid width 100%

问题描述

当我在网格中创建 button + entry + button 时，entry 居中但未完全填充该列.我如何通过 Entry 填充该列?

When i create button + entry + button in grid, entry was centered but not completely fill the column. How i can fill the column via 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()

推荐答案

使用 grid() 你可以在 Entry 的父级上使用 grid_columnconfigure()代码>

Using grid() you can use grid_columnconfigure() on parent of Entry

import tkinter as tk

root = tk.Tk()

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

root.mainloop()

<小时>

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()

<小时>

顺便说一句:使用:

---

BTW: using:

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

您将 grid() 的结果分配给 self.path 但 grid() 总是返回 None.

you assign result of grid() to self.path but grid() always return None.

如果你需要 self.path 然后做:

If you need self.path then do:

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

如果你不需要 self.path 那么你可以这样做:

If you don't need self.path then you could do:

tk.Entry().path.grid()
