Tkinter:如何使一个按钮与多个文本字段?

Question

我在tkinter中有这个表。但是，我想在每行中只有一个带有四个文本字段的按钮。(我现在每行有四个按钮)

基本上，我想将这四个按钮连接到一行中的一个按钮。我该怎么做呢?

from tkinter import *
class Table:

def __init__(self,root):

# code for creating table
for i in range(total_rows):
for j in range(total_columns):

self.e = Button(root, width=20,text = lst[i][j])

self.e.grid(row=i, column=j)
# take the data
lst = [(1,'Raj','Mumbai',19),
(2,'Aaryan','Pune',18),
(3,'Vaishnavi','Mumbai',20),
(4,'Rachna','Mumbai',21),
(5,'Shubham','Delhi',21)]
# find total number of rows and
# columns in list
total_rows = len(lst)
total_columns = len(lst[0])
# create root window
root = Tk()
t = Table(root)
root.mainloop()

Answer 1

我已经修改了你的代码，包括一个名为'工作'的Toplevel窗口，可以访问超级按钮。按钮的数量由表中的行数决定。

每个按钮连接到另一个Toplevel窗口称为'edit'。

'Edit'包含Label,Entry和Button对象。数量由表中的列数决定。

所有窗口都是可调整大小的，'工作'和'编辑'窗口可通过F1键访问。

转义键将通过messagebox关闭'top'表。

好的，这是最新的版本。

我把这个项目分成了两个python文件，一个是名为"dataffile .py"的数据文件，另一个是名为"Records.py"的代码文件。

'Datafile.py'必须与'Records.py. '分开保存。

记录代码完全可以通过更改Datafile.py

中的表数据来配置。通过添加或修改列和/或行来更改表数据将配置主程序。表、工作和编辑窗口由dataffile .py

中的行和列决定。另存为'Datafile.py'

import time
timedate = time.localtime()
year = timedate.tm_year
indice = [ "gender", "name", "location", "age", "birth"]
table = [
["Male",   "Raj",      "Mumbai",   19, year-19],
["Male",   "Aaryan",   "Pune",     18, year-18],
["Female", "Vaishnavi","Mumbai",   20, year-20],
["Female", "Rachna",   "Mumbai",   21, year-21],
["Male",   "Shubham",  "Delhi",    21, year-21],
["Male",   "Roger",    "New York", 17, year-17],
["Male",   "David",    "Sydney",   53, year-53],
["Female", "Jennifer", "London",   42, year-42]]

这是主程序'Records.py'。

另存为"Records.py">
