python - 有没有办法扩大Python中的GUI框？

Question

我正在尝试制作一个简单的句子生成器。代码可以工作，但我只是想知道是否有任何方法可以扩展 GUI 输入框？

它是这样的:

如有任何帮助，我们将不胜感激。

import tkinter as tk
from tkinter import Entry
import random
window = tk.Tk()

def movingVerb():
    verbs = ["goes to", "walks through", "runs through"]
    moveVerb = random.choice(verbs)
    return moveVerb
def anObject():
    anObject = objectEntry.get()
def Generate():
    UserName = nameEntry.get()
    moveVerb = movingVerb()
    place = placeEntry.get()
    noun = objectEntry.get()
    sentence = UserName + " " + moveVerb + " a " + place + " and finds a " + noun + " ." 
    result.delete(0, tk.END)
    result.insert(0, sentence)

UserNameLabel = tk.Label(window, text="Enter a name: ")
nameEntry = tk.Entry(window)
anObjectLabel = tk.Label(window,text="Enter an object: ")
objectEntry = tk.Entry(window)
placeLabel = tk.Label(window, text="Enter a place: ")
placeEntry = tk.Entry(window)
button = tk.Button(window, text="Generate story", command=Generate)
result = tk.Entry(window)

UserNameLabel.pack()
nameEntry.pack()
anObjectLabel.pack()
objectEntry.pack()
placeLabel.pack()
placeEntry.pack()
button.pack()
result.pack()
window.mainloop()

Answer 1

如果您想在调整窗口大小时展开小部件，则可以在 pack() 中以不同的组合使用 expand 和 fill 。一切都取决于您想要扩展哪个元素以及向哪个方向扩展。

.pack(fill='x')
.pack(fill='y')
.pack(fill='both')
.pack(expand=True, fill='x')
.pack(expand=True, fill='y')
.pack(expand=True, fill='both')

<小时/>

如果您想调整窗口大小以查看 Entry 中的所有新文本，则可以使用 widget.configure(width=...)。条目使用字符数作为宽度。

您可以使用句子的长度来更改宽度

result.configure(width=len(sentence))

或保持宽度至少 20 个字符

length = max(20, len(sentence))
result.configure(width=length)
