Python 程序在 PyCharm 中运行后，Tkinter 窗口会自动关闭 [英] Tkinter window closes automatically after Python program has run in PyCharm

问题描述

我正在 PyCharm 中编写一个小型 Python 游戏.我正在使用 Python 3.4 版的 Macbook 执行此操作.游戏会打开一个 Tkinter 窗口并向其中添加一些内容.但是，在运行游戏时，它会非常短暂地显示并立即关闭.

I am programming a small Python game in PyCharm. I am doing this on a Macbook with Python version 3.4. The game opens a Tkinter window and adds some stuff to it. However, when running the game, it shows up very briefly and closes immediately.

我在 Stackoverflow 上找到了一些提示，可以在游戏结束时添加输入(按关闭窗口").确实，这样可以保证窗口不会立即关闭，但是对于游戏来说并不实用.在游戏中，用户需要使用他的方向键来玩.所以在这种情况下添加 input(...) 没有用.如何防止窗口自动关闭?谢谢！

I found some tips here on Stackoverflow to add input('Press to close the window') at the end of the game. Indeed, this ensures that the window is not closed immediately, but it is not practical for the game. In the game, the user needs to use his arrow keys to play. So adding the input(...) is not useful in this case. How can I prevent the window to close automatically? Thanks!

代码下方:

from tkinter import *

# Scherm maken
HEIGHT = 500
WIDTH = 800
window = Tk()
window.title('Bellenschieter')
c = Canvas(window,width=WIDTH, height=HEIGHT, bg='darkblue')
c.pack()



# Duikboot maken
ship_id = c.create_polygon(5,5,5,25,30,15,fill='red')
ship_id2 = c.create_oval(0,0,30,30,outline='red')
SHIP_R = 15
MID_X = WIDTH/2
MID_Y = HEIGHT/2
c.move(ship_id, MID_X, MID_Y)
c.move(ship_id2, MID_X, MID_Y)

# Duikboot besturen
SHIP_SPD = 10
def move_ship(event):
    if event.keysym == 'Up':
        c.move(ship_id, 0, -SHIP_SPD)
        c.move(ship_id2, 0, -SHIP_SPD)
    elif event.keysym == 'Down':
        c.move(ship_id, 0, SHIP_SPD)
        c.move(ship_id2, 0, SHIP_SPD)
    elif event.keysym == 'Left':
        c.move(ship_id, -SHIP_SPD, 0)
        c.move(ship_id2, -SHIP_SPD, 0)
    elif event.keysym == 'Right':
        c.move(ship_id, SHIP_SPD, 0)
        c.move(ship_id2, SHIP_SPD, 0)
c.bind_all('<Key>', move_ship)

window.update()

input('Press <Enter> to end the program')

推荐答案

在设置小部件、事件处理程序后启动事件循环.

Start a event loop after setting up widgets, event handlers.

# input('Press <Enter> to end the program')  # (X)
window.mainloop()  # OR mainloop()

移除对input的调用.
