import Tkinter

from Tkinter import Tk, Frame, Entry, Button, Listbox, N, S, E, W

class TkPersonalActivityLog(object):

    def __init__(self):
        pass

    def configure_window(self, root):

        root.grid_columnconfigure(0, weight=1)
        root.grid_rowconfigure(0, weight=1)
        root.grid_rowconfigure(1, weight=1)
        root.grid_rowconfigure(2, weight=2)

        self.frame = Frame(root)
        self.frame.grid(sticky=N+E+S+W)
        self.frame.grid_columnconfigure(0, weight=2)
        self.frame.grid_rowconfigure(0, weight=2)
        self.frame.grid_rowconfigure(1, weight=2)
        self.frame.grid_rowconfigure(2, weight=2)

        self.entry = Entry(self.frame, bg='#e3ecfc')
        self.entry.grid(row=0, sticky=E+W)
        self.entry.focus_set()

        self.savebutton = Button(self.frame, text="Save and Minimize", fg="Black", command=self.cb_save_button)
        self.savebutton.grid(row=1)

        self.history = Listbox(self.frame)
        self.history.grid(row=2,sticky=N+S+E+W)

    def cb_save_button(self):
        act = (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), self.entry.get())
        self.history.insert(0, ' '.join(act))

    def mainloop(self):
        self.root = Tk()
        self.configure_window(self.root)
        self.root.mainloop()


if __name__ == '__main__':
    main = TkPersonalActivityLog()
    main.mainloop()

我想要 self.history 在调整整个窗口的大小时,将其调整到窗口的底部。事实上,它并没有这样做:

底部窗户的边缘。

sticky=N+S+E+W ?

如果你只是将Tkinter作为tk导入,你可以省去一些头痛。

尝试更改此选项:

from Tkinter import Tk, Frame, Entry, Button, Listbox, N, S, E, W

Import Tkinter as Tk

此外,您不需要导入 N, S, E, W sticky = "nsew" 效果与 sticky = N+S+E+W 您的主要问题不是列表框没有填充框架,而是您的 self.frame 未填充根窗口。

首先,让我们删除所有无用的权重。因为你的只被放置在 row=0, column=0 而且根窗口中没有其他小部件,因此不需要为其他行/列提供权重。

root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=1)
root.grid_rowconfigure(1, weight=1)
root.grid_rowconfigure(2, weight=2)

收件人:

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)

然后,让我们更改帧的权重,以便列表框展开。

self.frame.grid_columnconfigure(0, weight=2)
self.frame.grid_rowconfigure(0, weight=2)
self.frame.grid_rowconfigure(1, weight=2)
self.frame.grid_rowconfigure(2, weight=2)

收件人:

self.frame.grid_columnconfigure(0, weight=1)
self.frame.grid_rowconfigure(2, weight=1)

这应该可以解决您的大小调整问题。

#!/usr/bin/env python

import Tkinter as tk
import datetime

class TkPersonalActivityLog(object):

    def __init__(self, root):
        self.master = root
        self.master.rowconfigure(0, weight=1)
        self.master.columnconfigure(0, weight=1)

        self.frame = tk.Frame(self.master)
        self.frame.grid(sticky="nsew")
        self.frame.grid_columnconfigure(0, weight=1)
        self.frame.grid_rowconfigure(2, weight=1)

        self.entry = tk.Entry(self.frame, bg='#e3ecfc')
        self.entry.grid(row=0, sticky="ew")
        self.entry.focus_set()

        self.savebutton = tk.Button(self.frame, text="Save and Minimize", fg="Black", command=self.cb_save_button)
        self.savebutton.grid(row=1)

        self.history = tk.Listbox(self.frame)
        self.history.grid(row=2,sticky="nsew")

    def cb_save_button(self):
        act = (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), self.entry.get())
        self.history.insert(0, ' '.join(act))


if __name__ == '__main__':
    root = tk.Tk()
    main = TkPersonalActivityLog(root)
    root.mainloop()

此代码较短,通过使用 import Tkinter as Tk .
