Question

您好我是tkinter和编码的新手。我正在创建一个名为谷歌自行车的项目。我找到了一个instructable，我想通过添加一个开始菜单看起来更好。它使用python，我使用tkinter为它创建某种起始页面。我正在尝试创建一个按钮，我只需按下它即可启动该程序。这是我用来使tkinter看起来很漂亮的代码，有点像开始菜单。

import Tkinter as tk
from Tkinter import *
import ttk

def OpenServer():
      execfile("C:/users/Broadway Jewelry/Downloads/server/server2/server.py")

class Camacho(tk.Tk):
    def __init__(app):      
        tk.Tk.__init__(app)
        container = tk.Frame(app, width=800, height=500)
        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)
        app.frames = {}

        for F in (StartPage, Instructionspage, OptionsPage, DemoPage):
            frame = F(container, app)
            app.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")

        app.show_frame(StartPage)

    def show_frame(app, cont):
        frame = app.frames[cont]
        frame.tkraise()

class StartPage(Frame):
    def __init__(app, parent, controller):
        Frame.__init__(app, parent, background='black', width=800, height=500)
        earth = tk.PhotoImage(file="C:/Users/Broadway Jewelry/Desktop/Bluestamp/earth.gif")
        BGlabel = tk.Label(app,image=earth)
        BGlabel.image = earth
        BGlabel.place(x=300,y=0,width=400,height=400)

        StartProgram = Button(app, text="Start Google Bike",
                          bd=10, command=OpenServer)
        StartProgram.place(x=100,y=75,width=200,height=44)

        Instructions = Button (app, text="Instructions", bd=10,
                           command=lambda: controller.show_frame(Instructionspage))
        Instructions.place(x=100,y=150,width=200,height=44)


        Options = Button (app, text="Options/Setup", bd=10,
                      command=lambda: controller.show_frame(OptionsPage))
        Options.place(x=100,y=225,width=200,height=44)

        Quit = Button (app, text="Exit Program", command=quit, bd=10)
        Quit.place(x=100,y=300,width=200,height=44)

class Instructionspage(Frame):
    def __init__(app, parent, controller):
        Frame.__init__(app, parent, background='black', width=800, height=500)

        label = tk.Label(app, text="Instructions\n \nPedal=go forward\npress button=reverse\nbutton side to steer",
                     font=(200), background='black', fg='white')
        label.place(x=300,y=0,width=400,height=400)

        StartProgram = Button(app, text="Start Google Bike", bd=10, command=OpenServer)
        StartProgram.place(x=100,y=225,width=200,height=44)

        GoBack = Button (app, text="Go Back", bd=10,
                     command=lambda: controller.show_frame(StartPage))
        GoBack.place(x=100,y=300,width=200,height=44)

class OptionsPage (Frame):
    def __init__(app, parent, controller):
            Frame.__init__(app, parent, background='black', width=800, height=500)

            GoBack = Button (app, text="Go Back", width=50, bd=10,
                         command=lambda: controller.show_frame(StartPage))
            GoBack.place(x=100,y=300,width=200,height=44)

            StartProgram = Button(app, text="Start Google Bike", bd=10, command=OpenServer)
            StartProgram.place(x=100,y=225,width=200,height=44)

            ShowDemo = Button (app, text="Show Demo Screen", bd=10,
                           command=lambda: controller.show_frame(DemoPage))
            ShowDemo.place(x=100,y=150,width=200,height=44)

class DemoPage (Frame):
    def __init__(app, parent, controller):
            Frame.__init__(app, parent, background='black', width=800, height=500)
            earth = tk.PhotoImage(file="C:/Users/Broadway Jewelry/Desktop/Bluestamp/Google-Bike.gif")
            BGlabel = tk.Label(app,image=earth)
            BGlabel.image = earth
            BGlabel.place(x=300,y=0,width=400,height=400)

            GoBack = Button (app, text="Go Back", width=50, bd=10,
                     command=lambda: controller.show_frame(OptionsPage))
            GoBack.place(x=100,y=300,width=200,height=44)


app = Camacho()
app.mainloop()

我正在考虑找到一些关闭tkinter窗口的方法，让python运行google自行车。如果有人能帮助你，非常感谢

只需向OpenServer添加一行（这似乎是运行真实程序的函数）：

def OpenServer():
    execfile("C:/users/Broadway Jewelry/Downloads/server/server2/server.py")
    app.destroy()

我还建议，在任何给定的类中，您将该类的实例称为标准self而不是app。实际上，它给人的印象是，您在程序结束时实例化的Camacho对象正在传递并由其app名称引用。但实际情况并非如此：在Camacho中，app可以引用任何Camacho对象，即使您执行test = Camacho()之类的操作也是如此。在Camacho内，test对象将自称为app。在其他类中，它更具误导性，因为名为Camacho的{{1}}对象实际上并非app，而是app。< / p>

困惑？即使我觉得它很乱 - 这就是为什么使用controller更好，并避免在多个范围内使用相同的表观变量名。

使用tkinter作为另一个python程序的开始菜单
