Question

我遇到了tkinter的问题，我不确定如何判断用户所在的帧，并将其保存到变量中。我需要（我认为）这些信息能够在多个帧之间切换。

def check(value):  # checks to see if the button that was click was the correct answer

if value:
    print("you picked the right answer!")
    answers.increase()
    frame1.grid_remove()
    frame2.grid(row=5)

else:
    print("sorry thats not right")
    frame1.grid_remove()
    frame2.grid(row=5)

此功能由以下按钮调用：

q1choice1 = Button(frame1, height=2, width=50, text=question1[1].text, command=lambda: check(question1[1].value))
q1choice2 = Button(frame1, height=2, width=50, text=question1[2].text, command=lambda: check(question1[2].value))
q1choice3 = Button(frame1, height=2, width=50, text=question1[3].text, command=lambda: check(question1[3].value))
q1choice4 = Button(frame1, height=2, width=50, text=question1[4].text, command=lambda: check(question1[4].value))

而不是frame1.grid_remove和frame2.grid我希望能够有一个变量，如x.grid_remove（）y.grid（row =），这样这个函数可以在所有帧之间切换。如果需要，我可以发布剩下的代码，但我试着将其保留在相关的内容中。

谢谢，

完整代码：

from tkinter import *

# class for the correct answers in choices


class Correct(object):
    value = True

    def __init__(self, text):
        self.text = text

# class for incorrect answers


class Incorrect(object):
    value = False

    def __init__(self, text):
        self.text = text

# this class allows me to increment a var for num of correct answers


class CountRight(object):
    def __init__(self):
        self.right = 0

    def increase(self):
        self.right +=1


answers = CountRight()
framecount = CountRight()
framecount.increase()

def check(value):  # checks to see if the button that was click was the correct answer
    framecount.increase()
    framestring = ["frame" , framecount.right]
    framestring = str(framestring)
    framestring = "".join(framestring)
    framestring = framestring.replace("'", "")
    framestring = framestring.replace(",", "")
    framestring = framestring.replace(" ", "")


    print(framestring)
    if value:
        print("you picked the right answer!")
        answers.increase()
        framestring.grid_remove()
        framestring.grid(row=5)

    else:
        print("sorry thats not right")
        frame1.grid_remove()
        frame2.grid_remove()

    win.update_idletasks()
    width = win.winfo_width()
    frm_width = win.winfo_rootx() - win.winfo_x()
    win_width = width + 2 * frm_width
    height = win.winfo_height()
    titlebar_height = win.winfo_rooty() - win.winfo_y()
    win_height = height + titlebar_height + frm_width
    x = win.winfo_screenwidth() // 2 - win_width // 2
    y = win.winfo_screenheight() // 2 - win_height // 2
    win.geometry('{}x{}+{}+{}'.format(width, height, x, y))
    win.deiconify()

mainloop()

Answer 1

为什么不在每次帧更改时都尝试设置变量，所以在更改帧的代码中添加另一个参数，在该函数中将获取帧的名称，然后在函数中它将设置a（Global ??）变量到该名称，可以随时读取吗？

所以例如

def change(..., newFrame):
    global curFrame
    curFrame = newFrame

change()是您用来将框架更改为另一个

的功能

这将添加到用于更改框架的函数中，这将使用一个全局变量，可以在任何位置读取，您设置为保存更改时更改的框架的值

跟踪按钮按下哪个框架用户？
