对于我要创建的用于编辑MIDI文件的程序,我导入了tkinter.messagebox
模块。我正在使用的消息框功能是askokcancel
。我希望在选择 ok 后关闭所有父窗口和子窗口。我该怎么做?
我已经尝试在其他站点上查看操作方法,但没有找到任何答案。
from tkinter import *
import tkinter.messagebox
class Window(Frame):
def init_window(self):
menu = Menu(self.master)
self.master.config(menu=menu)
file = Menu(menu)
file.add_command(label="Exit", command=self.client_exit)
menu.add_cascade(label="File", menu=file)
def exit(self):
exit()
def client_exit(self):
messagebox.askokcancel('Exit?', 'Are you sure you want to exit?', default='ok')
#Here, I want the "exit" function to be the function.
if self.reading:
self.top.quit()
app = Window(tk)
这只是我共享的代码示例。如果其他代码可能存在错误,我将与您分享。

public void intArray()
{
//create an int array called num that will store 4 elements
int[] num = {32,26,19,40};
//assign 32 to index 0
//assign 26 to index 1
//assign 19 to index 2
//assign 40 to index 3
//change index 3 to 57
num[3] = 57;
}
//write a line of code to print length of array: Length of array of :
public static void main(String[]args)
{
System.out.println("The length of the array is " + num.length);
//write a line of code to print index 3: Index 3 is :
System.out.println("Index three is " + num[3]);
//create a for loop to loop through and print all elements in the array
for(int element: num)
{
System.out.println(element);
}
}
或:
def client_exit(self):
MsgBox = messagebox.showinfo('Exit?', 'Are you sure you want to exit?',icon = 'warning')
if MsgBox == 'ok':
#Some code
