Python 3.4 Tkinter：框架和命令问题

Question

所以在我的代码中，我试图在第一帧（徽标页）上创建一个按钮，以便在单击时关闭该帧，然后打开另一个帧（介绍战斗）。但是，当前按下按钮时，第一帧被删除，但下一帧不显示，留下一个空白窗口。我认为正在发生的事情是下一帧出现了，但是由于它的所有小部件都是在帧被打包之前打包的，所以它们不会出现。我如何才能显示所有应该在下一帧中的小部件？这是代码。

如果我对问题的理解正确，您只需这样做。

def createIntroFightFrame(self):

    self.IntroFrame=Frame(self.myParent) # Notice I'm using self.myParent here

    self.IntroFrame.place(x=0, y=0) # Place this here instead of in `showIntro()`

    self.IntroBG=Label(self.IntroFrame, image=Pic2)
    self.IntroBG.image=Pic2
    self.IntroBG.place(x=0,y=0)

    self.text=Message(self.IntroFrame, fg='black',text="""Flaming Arrows whizz over your hair, War rages around you. Suddenly, it charges at you. A 8 foot tall mechanical beast the enemy have been training for war. You have no chance but to fight it. You swing your sword as hard as you can...Only to leave a minor dent on it's armor. With one blow from its club, you fall unconscious."""
    , font='Times 15 bold')
    self.text.place(x=70, y=50)
    self.FinishSlide1=Button(self.IntroFrame, text='Next', command = self.WakingUp, width=10)
    self.FinishSlide1.place(x=500, y=700)

然后，这样称呼它：

def showIntro(self): #Transition into Intro Fight frame.
    self.LogoFrame.destroy()
    self.createIntroFightFrame()

@Marcin 似乎对 Tkinter 很熟悉。我从来没有使用过它，所以我不知道它的特殊性或所涉及的具体方法。如果我在上下文中没有意义，请参考他的回答。

Answer 2

这似乎是因为您使用了地点几何管理器。我将其更改为打包一个，它似乎按预期工作。我还从下面的代码中删除了图像，因为我没有您的图像文件并且无法运行它。
