Python 3.4 Tkinter：框架和命令问题

Question

因此，在我的代码中，我正在尝试在第一帧（徽标页面）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（Intro Fight）。 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。 我认为正在发生的是下一帧出现，但由于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。 我怎样才能将所有应该出现在下一帧中的小部件显示出来？ 这是代码。

Answer 1

如果我正确理解问题，你只需要这样做。

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()

放弃

@Marcin似乎熟悉Tkinter。 我从来没有使用它，所以我不知道它的特点或涉及的具体方法。 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场所几何管理器。 我改变它打包一个，它似乎按预期工作。 我还从下面的代码中删除了图像，因为我没有你的图像文件，无法运行它。
