python3.4tkinter：框架和命令问题

Question

所以在我的代码中，我试图在第一个框架（Logo页面）上创建一个按钮，这样当点击时，它会关闭该框架，然后打开另一个框架（Intro-Fight）。然而，当前按下按钮时，第一帧会被删除，而下一帧则不会出现，留下一个空白窗口。我认为下一帧出现了，但是由于它的所有小部件都在帧打包之前打包好了，所以它们不会出现。我怎样才能让下一帧中的所有小部件都显示出来呢？这是密码。在

Answer 1

如果我正确地理解了这个问题，你就必须这么做。在

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：

@Marcin似乎对Tkinter很熟悉。我从来没有用过它，所以我不知道它的特殊性或涉及的具体方法。如果我的回答在上下文中没有意义，请参考他的答案。在

这似乎是因为您使用了“放置几何图形管理器”。我把它换成了packone，它看起来像预期的那样工作。我还从下面的代码中删除了图像，因为我没有你的图像文件，无法运行它。在
