Question

我第一次使用tkinter。当我执行此代码时，总会出现一些错误。我只想要一个简单的python项目的gui。错误是 widgetName，self._w）+ extra + self._options（cnf）） _tkinter.TclError：无法调用＆＃34;按钮＆＃34;命令：应用程序已被销毁

import tkinter
import os


MASTER = tkinter.Tk()
REVIEW_CONTENT_RAW = []
REVIEWS_SEL_FILM = []







def getReviewFileName(filmNum):
    basepath = os.path.abspath("..").split("/src")
    filepath = basepath[0] + "/resources/reviews"
    filename = filepath + "/review_film" + str(filmNum) +".txt";
    return filename


def loadReviewContents():
    global REVIEW_CONTENT
    for i in range(1,6):
        f = open(getReviewFileName(i), mode='r')
        fileContent = f.read().split("\n")
        REVIEW_CONTENT_RAW.append(fileContent)

def getFilmName(filmIndex):
    content = REVIEW_CONTENT_RAW[filmIndex]
    fTitle = content[0]
    return fTitle 

def getReviewListByMovie(filmIndex):
    reviewList = REVIEW_CONTENT_RAW[filmIndex]
    return reviewList

def setReviewsForSelectedFilm(filmIndex):
    global REVIEWS_SEL_FILM
    REVIEWS_SEL_FILM = getReviewListByMovie(filmIndex) 


def getReviewsForSelectedFilm():
    return REVIEWS_SEL_FILM

def populateUI():

    return getReviewsForSelectedFilm()


def buttonClickActionforFilm1():

    setReviewsForSelectedFilm(0)
    MASTER.destroy()

def buttonClickActionforFilm2():
    setReviewsForSelectedFilm(1)
    MASTER.destroy()

def buttonClickActionforFilm3():
    setReviewsForSelectedFilm(2)
    MASTER.destroy()

def buttonClickActionforFilm4():
    setReviewsForSelectedFilm(3)
    MASTER.destroy()

def buttonClickActionforFilm5():
    setReviewsForSelectedFilm(4)
    MASTER.destroy()



x = populateUI()
print(x)

Answer 1

这是您的违规行MASTER.destroy()

您在此处销毁Tk()根MASTER窗口，因此方法名称destroy()，以及处理窗口小部件，命令等的GUI事件线程那么，你不能调用你的按钮命令。

不能调用＆＃34;按钮＆＃34;命令：应用程序已被破坏
