Question

我有这个代码，一旦用户点击其中一个选项，我试图让第一帧变灰，这样用户就无法改变到其他选择。但是当我运行它时，它甚至在用户选择之前就已经灰显了框架。我还想让第二帧变灰，直到用户点击/选择第一帧。有人可以帮忙吗？

Answer 1

在开始时，specialistchoose.get()的值为0，并且对if按钮的检查不是动态的。

Radiobutton内置command，每按一次按钮就会对其进行评估。您可以使用它来停用按钮。

像这样：

from Tkinter import *

def func():
    for child in f2.winfo_children():
        child.configure(state = 'disable')

import tkMessageBox
import ttk

root = Tk()

root.title("Pantai Hospital")
root.geometry("200x200")

Label(root, text = "Welcome to Pantai Hospital!").grid()


f1 = Frame(root, width = 350, height = 110)

f2 = Frame(f1, relief = GROOVE, borderwidth = 2)

l9 = Label(f2, text = "Choose your specialist:")
l9.grid()

specialistchoose = IntVar()

r1 = Radiobutton (f2, text = "Cardiology", variable = specialistchoose, value = 1, command=func)
r1.grid(row = 1, column = 0, stick = W)

r2 = Radiobutton (f2, text = "Gastroenterology", variable = specialistchoose, value = 2, command=func)
r2.grid(row = 1, column = 1,stick = W )

r3 = Radiobutton (f2, text = "Dermatology", variable = specialistchoose, value = 3, command=func)
r3.grid (row = 1, column = 2,stick = W )

r4 = Radiobutton (f2, text = "Psychiatry", variable = specialistchoose, value = 4, command=func)
r4.grid (row = 3, column = 0,stick = W )

r5 = Radiobutton (f2, text = "Dentist", variable = specialistchoose, value = 5, command=func)
r5.grid(row = 3, column = 1,stick = W  )

f2.place(relx = 0.01, rely = 0.125, anchor = NW)
Label(f1, text = "Specialist").place(relx = .06, rely = 0.125, anchor = W)

f1.grid()



f3 = Frame(root, width = 350, height = 110)
f4 = Frame(f3, relief = GROOVE, borderwidth = 2)

l15 = Label (f4, text = "Choose your preferred day:")
l15.grid(columnspan = 2, sticky = W)

day = IntVar()

cb1 = Checkbutton(f4, text = "Monday", variable = day, onvalue = 1, offvalue = 0)
cb1.grid(row = 4, column = 0,stick = W )
cb2 = Checkbutton(f4, text = "Tuesday", variable = day, onvalue = 2, offvalue = 0)
cb2.grid(row = 4, column = 1,stick = W )
cb3 = Checkbutton(f4, text = "Wednesday", variable = day, onvalue = 3, offvalue = 0)
cb3.grid(row = 4, column = 2, stick = W)
cb4 = Checkbutton(f4, text = "Thursday", variable = day, onvalue = 4, offvalue = 0)
cb4.grid(row = 4, column = 3,stick = W )
cb5 = Checkbutton (f4, text = "Friday", variable = day, onvalue = 5, offvalue = 0)
cb5.grid(row = 5, column = 0, stick = W )
cb6 = Checkbutton(f4, text = "Saturday", variable = day, onvalue = 6, offvalue = 0)
cb6.grid(row = 5, column = 1, stick = W )
cb7 = Checkbutton (f4, text = "Sunday", variable = day, onvalue = 7, offvalue = 0)
cb7.grid(row = 5, column = 2, stick = W )

f4.place(relx = 0.01, rely = 0.125, anchor = NW)
Label(f3, text = "Day").place(relx = .06, rely = 0.125, anchor = W)

f3.grid()
root.mainloop()

您的代码附注：

在这种情况下，代码中的if语句始终会评估True，'Cardiology' or 'Gastroenterology'为True

您应该使用：

if specialistchoose.get() != 'Cardiology' or specialistchoose.get() != 'Gastroenterology' or specialistchoose.get() != 'Dermatology' or specialistchoose.get() != 'Psychiatry' or specialistchoose.get() != 'Dentist':

单击radiobutton Tkinter后灰显一帧
