我無法獲得mButton1
以顯示一個菜單,顯示Orlando
及其下方的Cancun
。 我正在嘗試構建一個窗口小部件按鈕,點擊時它會在菜單中顯示2個城市,例如預訂航班時。使用tkinter無法看到python上的菜單按鈕
from tkinter import *
class App:
def __init__(self, master):
frame = Frame(master)
frame.grid()
self.label1 = Label(frame, text = "Destination:")
self.label2 = Label(frame, text = "Adults:")
self.label3 = Label(frame, text = "Child:")
self.label1.grid(row=0)
self.label2.grid(row=1)
self.label3.grid(row=2)
self.entry2 = Entry(frame)
self.entry3 = Entry(frame)
self.entry2.grid(row=1,column = 1)
self.entry3.grid(row=2,column = 1)
self.button = Checkbutton(frame, text="Roundtrip:")
self.button.grid(row=3)

「__init__」是在它自己的行縮進得當,(並且對每邊,你可能有兩個下劃線,但它顯示爲大膽,因爲它沒有格式化爲代碼)http://www.diveintopython.net/object_oriented_framework/defining_classes.html#d0e11720 –
