请帮我。这很奇怪。看这个：
#!/usr/bin/env python
from Tkinter import *
import database
def insertBook():
insertWindow = Tk()
insertWindow.title("Inserisci un nuovo romanzo nel database")
checkvars = []
checkvars.append(IntVar())
checkvars.append(IntVar())
Checkbutton(insertWindow, text = 'male', variable=checkvars[0]).pack()
Checkbutton(insertWindow, text = 'female', variable=checkvars[1]).pack()
Button(insertWindow, text= 'show', command=lambda: show(checkvars)).pack()
insertWindow.mainloop()
def show(checkvars):
print checkvars[0].get()
print checkvars[1].get()
class AppBase:
def __init__(self, parent):
self.quadro1 = Frame(parent)
self.quadro1.pack()
self.welcolmeLabel = Label(self.quadro1, text = "Benvenuto nel database dei romanzi di Lory")
self.welcolmeLabel.pack()
self.insertButton = Button(self.quadro1, command = insertBook);
self.insertButton["borderwidth"] = 1
self.insertButton["text"] = "Inserisci un libro nel database"
self.insertButton["background"] = "pink"
self.insertButton.pack(side = "left")
self.quadro2 = Frame(parent)
self.quadro2.pack()
self.searchButton = Button(self.quadro1);
self.searchButton["borderwidth"] = 1
self.searchButton["text"] = "Ricerca nel database"
self.searchButton["background"] = "blue"
self.searchButton.pack(side = "left")
self.showButton = Button(self.quadro1);
self.showButton["borderwidth"] = 1
self.showButton["text"] = "Mostra i generi di libro"
self.showButton["background"] = "violet"
self.showButton.pack(side = "left")
self.exitButton = Button(self.quadro2, text = "Uscita", borderwidth = 1, background = "red", command = self.quadro1.quit)
self.exitButton.pack(side = RIGHT, pady = 20)
if __name__ == '__main__':
mainFinestra = Tk()
mainFinestra.title('Database di Romanzi')
app = AppBase(mainFinestra)
listvars = []
listvars.append(IntVar())
listvars.append(IntVar())
Checkbutton(mainFinestra, text = 'male', variable=listvars[0]).pack()
Checkbutton(mainFinestra, text = 'female', variable=listvars[1]).pack()
Button(mainFinestra, text= 'show', command=lambda: show(listvars)).pack()
mainFinestra.mainloop()
似乎检查按钮变量仅在 mainFinestra 中设置。如果我在另一个新窗口（例如 insertWindow）中创建检查按钮，则 checkvars 中的变量始终为 0，即使这些按钮被选中。相反，如果我尝试检查 mainFinestra 中的检查按钮，则函数“show”如果被检查则返回 1。有什么不同？拜托，这个项目对我很重要。谢谢
