从一个类访问 Tk Inter 小部件并在另一个类上显示

Question

这是一个化学测验，我创建了 QUESTIONSTARTER 类作为对象。我正在尝试从该类访问小部件并将其放置在 STAGE1 类中，以便我可以将它们网格化，但在窗口上，这些框架上没有显示任何内容，所以我不知道该怎么做。 （我也想从按钮数据访问 tk 小部件，这是另一个类，但由于空间问题我无法显示）

class QUESTIONSTARTER(tk.Frame):
 def __init__(self, parent, controller):
    tk.Frame.__init__(self, parent)
    self.controller = controller
    self.Attmepts = 3
    self.Points = 0
    self.NumberOfTimesSubmitBeenPressed = 0
    self.WordedQuestion = tk.Label(self)
    self.PointsLabel = tk.Label(self,text = self.Points)        
    self.AttemptsDisplayed = tk.Button(self, text = self.Attempts)
    self.AttemptsDisplayedText = tk.Label(self, text = "Attempts Displayed: ")

 def SetQuestionIntro(self):     
    WordedQuestion.config(text = "Many different organic compounds are synthesised by various routes but they may need specific type of reagents and conditions.")


 def SubmitClicked(self, Attempts):

    if self.Attempts == 1:
        NumberOfTimesSubmitBeenPressed += 1
    elif self.Attempts == 2:
        NumberOfTimesSubmitBeenPressed += 2
    elif self.Attempts == 3:
        NumberOfTimesSubmitBeenPressed += 2

    if NumberOfTimesSubmitBeenPressed == 3:
        controller.show_frame(F)
    else:
        print ("There was an Error")    

    #call at random the specific products from product database
    #depending on class run
 def ButtonPressed(self,ReagentsList):
    ReagentsList[0] = CorrectReagent
    self.CorrectReagent.configure(bg = 'green')
    IncorrectReagentsList = []
    IncorrectReagentsList.append(ReagentsList[1])
    IncorrectReagentsList.append(ReagentsList[2])
    IncorrectReagentsList.append(ReagentsList[3])

    for Reagents in IncorrectReagentsList:
        tk.Button[Reagents].configure(bg = "red")

    ConditionsList[0] = CorrectCondition
    self.CorrectCondition.configure(bg = "green")
    IncorrectConditionsList = []
    IncorrectConditionsList.append(ReagentsList[1])
    IncorrectConditionsList.append(ReagentsList[2])
    IncorrectConditionsList.append(ReagentsList[3])

    for Reagents in IncorrectReagentsList:
        tk.Button[Reagents].configure(bg = "red")




 def AllocatePointsStage1(self,frames ,ButtonPressed, Attempts, Points):


      while self.Attempts == 1:
           if self.ReagentOption1.bg == 'green' or self.ConditionOption1.bg == 'green':
            self.Points += 20
            controller.show_frame(Stage2)
            self.frames.remove(Stage2)

            self.show_frame(Stage2)
            self.frames.remove(Stage2)

你不能做你想做的事。小部件存在于具有父/子关系的树状结构中，小部件不能在树上移动，然后在不同的分支下移动。此外，任何给定的小部件一次不能在多个位置显示，因此如果您将其放在页面 A 中，为了将其放入页面 B，您必须将其从页面 A 中删除。

唯一的解决方案是复制小部件。如果它们要显示相同的数据，您可以让它们共享相同的变量（即：textvariable 属性）。当两个或多个小部件共享相同的textvariable 时，在一个小部件中所做的更改将立即在另一个小部件中进行。
