每当我单击应用程序上的保存按钮时，它都会打开一个正常工作的保存对话框和一个在我尝试关闭它时立即崩溃的 tkinter 窗口.这是我以某种方式生成随机窗口的代码:

Whenever I click the save button on my app, it opens a save dialogue that works correctly and a tkinter window that crashes as soon as I try to close it. Here is my code that somehow makes the random window:

import tkFileDialog,pygame

pygame.init()

screen = pygame.display.set_mode((640,360))

pygame.display.set_caption("Idea Processor")

# code is cut here

try:
    ideasetupfonts = pygame.font.SysFont("Ubuntu", 36, False, False)
except:
    ideasetupfonts = pygame.font.SysFont("Arial", 36, False, False)
# TextNameToBlit = ideasetupfonts.render(" TEXT HERE ",1,(0,0,0))

Potato = True
ShowToolbar = True
newSaveFile = {"Hello World":(50,50)}



def SaveFile():
    filename = tkFileDialog.asksaveasfilename(**{"title":"Save Idea...","defaultextension":".txt","filetypes":[("text files", ".txt")],})
    if filename:
        saveFile = open(filename, 'w')
        print >>saveFile,newSaveFile
        saveFile.close()

while Potato:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            Potato = False
    screen.fill(white)

    # and here

    mousex,mousey = pygame.mouse.get_pos()

    # SaveFile button
    if mousex>=0 and mousex<=32 and mousey>=0 and mousey<=32 and pygame.mouse.get_pressed() == (True, False, False) and ShowToolbar:
        SaveFile()


    # and here

    pygame.display.flip()

pygame.quit()

推荐答案

该窗口是默认 Tk 元素，如果您尚未创建前一个窗口小部件，则在创建 Tkinter 小部件时创建该窗口.这是因为 tkFileDialog 建立在 Tkinter 之上.我建议您自己创建该元素并通过调用其 withdraw 方法将其隐藏.

That window is the default Tk element that is created when a Tkinter widget is created if you haven't created a previous one. This happens because tkFileDialog is built on top of Tkinter. I suggest you to create that element yourself and hide it by calling its withdraw method.

import Tkinter, tkFileDialog, pygame

root = Tkinter.Tk()
root.withdraw()

顺便说一下，我已经看到您已将 Pygame 循环的标志命名为 Potato.我不知道它与此变量的实际使用有何关系，但我强烈建议您为类、变量和模块使用有意义的名称.这是Object Mentor 的一篇文章(这是优秀书籍的一部分)Clean Code") 专门关于命名，我希望你觉得它有用.

As a side note, I have seen that you have named the flag for your Pygame loop Potato. I don't know how it could be related with the real use of this variable, but I strongly recommend you to use meaningful names for your classes, variables and modules. Here it is an article from Object Mentor (which is part of the excellent book "Clean Code") exclusively about naming, I hope you find it useful.
