Question

那么,我们如何能够从1到10个箱中获得价值,然后将其成一个箱(最大:100)? 之后,结果又出现在TKINTER的文字箱中?

我尝试了.get()方法以获得这一数值,然后我将其乘以100。然后,我使用<代码>.insert()方法,显示结果形成一个文本箱,但该文本却做了一些工作。

How can we get the value of a Spinbox (from 1 to 10) then multiply it into a number (ex: 100)

I tried the .get() method to get the value, then I multiplied it by 100. Then I used the .insert() method to display the result in a textbox, but it didn t work that well

Add three widgets; Spinbox, Text and Button
Create function called value_changed

Edit: re-work in value_changed()

Snippet:

import tkinter as tk
from tkinter import ttk


# root window
root = tk.Tk()
root.geometry( 300x200 )
root.resizable(False, False)
root.title( Spinbox Demo )

def value_changed():
    cal = current_value.get()
    y = 100
    ca= int(cal) * y
    textbox.insert(tk.END, ca)

        
textbox = tk.Text(root, width=25, height=5)
btn = tk.Button(root, text=r Click , command= value_changed)
 
# Spinbox
current_value = tk.StringVar(value=1)
spin_box = ttk.Spinbox(
    root,
    from_=1,
    to=10,
    textvariable=current_value,
    wrap=True)
 
spin_box.pack()
textbox.pack()

btn.pack(pady =10)

root.mainloop()
