获取数组中按钮的索引（按下时）

Question

我在数组中保存了一些按钮：

buttons = []
labels.append(tk.Label(fr2, text="", pady=15))
labels.append(tk.Label(fr3, text="", pady=15))

稍后我访问数据库表并使用“for in”循环该表，以便从程序中的表中获取所有行。对于每一行，我都会激活一个带有网格的按钮。

i = 0
    if len(records) > 0:
        for row in records:
            print("current_date", ", target date")
            print(current_date, row[2])

            date = current_date - row[2]

            labels[i] = tk.Label(fr2, text=row[1], pady=15)
            labels[i].grid(row=i, column=0, sticky='we')
            labels[i+1] = tk.Label(fr3, text=date, pady=15)
            labels[i+1].grid(row=i, column=0, sticky='we')
            buttons[i] = tk.Button(fr4, text="Restart", command=restart, pady=13)
            buttons[i].grid(row=i, column=0, sticky='we')
            buttons[i+1] = tk.Button(fr5, text="Delete", command=delete, pady=13)
            buttons[i+1].grid(row=i, column=0, sticky='we')

            i = i + 1

如何获取程序运行时我放在的按钮的索引？

Answer 1

您可以将参数传递给您用作命令的函数。

示例：

def myButttonCommand(index):

   print("this is the "+index+"th' button")

buttons = []

for i in range (0,10):

   buttons[i] = tk.Button(command=myButtonCommand(i))
