我正在尝试制作我的第一个GUI程序。问题是,我无法弄清楚如何制作一个主菜单,它会在点击一个按钮后切换到其中一个程序。
#Dev by Mkee
from Tkinter import *
import tkMessageBox
#Main Stuff
app = Tk()
app.title("Mkee's Tools")
app.geometry('300x200')
#modules
class Programs:
def Shuffle():
app2 = Tk()
app2.title("Shuffle")
app2.geometry('300x200')
app2.mainloop()
#end of modules
labelText = StringVar()
labelText.set('')
label1 = Label(app, textvariable=labelText, height=4)
label1.pack()
button1 = Button(app, text='Shuffle', width=30, command=Programs.Shuffle)
button1.pack(side='right', padx=5,pady=1)
app.mainloop()
我知道我做错了。我只是不知道该怎么做,所以我尝试了它怎么可能。请帮帮我。
答案 0 :(得分:1)
您可以调用pack_forget()隐藏小部件,然后(稍后)
pack
再次向他们展示:
Tkinter是单线程的,mainloop
运行主事件循环。因此,您不应该拨打mainloop
两次。
