启用和禁用多个复选框CustomTkinter

Question

这可能是个问题。

但我一直在绞尽脑汁，试图启用基于无线电按钮的复选框。

我所做的是基于数组(即dc_ma1 )创建一个多个复选框，并使其进入禁用状态。单选按钮将根据用户选择启用或禁用复选框。

下面是一些代码：：

from tkinter import *
import customtkinter

customtkinter.set_appearance_mode("System")  # Modes: "System" (standard), "Dark", "Light"
customtkinter.set_default_color_theme("blue")  # Themes: "blue" (standard), "green", "dark-blue"
root = customtkinter.CTk()   

root.minsize(300, 300) 
dc_ma1 = ["7190", "7189", "6264", "6262"]
dc_ma1_l=[str(i) for i in range(len(dc_ma1))]
print (dc_ma1_l)
selected_dc=[]

root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=0)
frame_lower_left = customtkinter.CTkFrame(master=root, corner_radius= 0)
frame_lower_left.grid(row=1, column=0, sticky="nswe", padx=20, pady=20)

frame_lower_left.rowconfigure((0, 1, 3 , 4), weight=0)
frame_lower_left.columnconfigure((0, 1, 2, 3, 4, 5), weight=1)

def cb_state():
    print (str(radio_CB.get()))

    if radio_CB.get() == 1:
        print("radio is 1")
        for x in range(len(dc_ma1)):
            #print(dc_ma1)
            check_CB1.configure(state="normal")     
    else:
        print("radio is 0")    

frame_radio = customtkinter.CTkFrame(master=frame_lower_left)
frame_radio.grid(row=0, column=0, columnspan=6, pady=20, padx=20, sticky="nsew")
frame_cb = customtkinter.CTkFrame(master= frame_lower_left)
frame_cb.grid(row=1, column=0, columnspan = 6, pady=20, padx=20, sticky="nsew")
frame_cb.pack_forget()

frame_cb.grid_columnconfigure(4, minsize=10)   # empty row with minsize as spacing
frame_cb.columnconfigure(4, weight=1)


# radio button to Disable and disable CB
radio_CB = IntVar(value=0)
label_radio_group = customtkinter.CTkLabel(master=frame_radio, text="Combiner Box Configuration:")
label_radio_group.grid(row=0, column=0, pady=10, padx=10, sticky="w", columnspan = 5)

radio_button_1 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=0, command=cb_state, text= "Disable Checkbox")
radio_button_1.grid(row=0, column=10, pady=20, padx=10, sticky="w", columnspan = 5)
radio_button_2 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=1, command=cb_state, text="Enable Checkbox")
radio_button_2.grid(row=0, column=20, pady=20, padx=10, sticky="w", columnspan = 5)

for x in range(len(dc_ma1)):
    dc_ma1_l[x]=IntVar(0)
    #print(dc_ma1_l)
    y=dc_ma1_l[x]
            
    check_CB1 = customtkinter.CTkCheckBox(master= frame_cb, text="CB " + str(x+1), variable=dc_ma1_l[x],offvalue=0,onvalue=1, command=lambda x=dc_ma1[x],y=dc_ma1_l[x]:add_remove(x,y))
    check_CB1.grid(row=2, column=x, pady=10, padx=10, sticky="nsew")
    check_CB1.configure(state="disabled")

root.mainloop()

当我尝试启用复选框时，它只启用最后一个复选框。我做错什么了？

补充一下，这是基于这里的注释的工作代码。正如@a 1668所强调的那样，我需要使用列表或字典来存储复选框的引用：

from tkinter import *
import customtkinter

customtkinter.set_appearance_mode("System")  # Modes: "System" (standard), "Dark", "Light"
customtkinter.set_default_color_theme("blue")  # Themes: "blue" (standard), "green", "dark-blue"
root = customtkinter.CTk()   

root.minsize(300, 300) 
dc_ma1 = ["7190", "7189", "6264", "6262"]
dc_ma1_l=[str(i) for i in range(len(dc_ma1))]
print (dc_ma1_l)
selected_dc=[]

root.grid_columnconfigure(0, weight=1)
root.grid_rowconfigure(0, weight=0)
frame_lower_left = customtkinter.CTkFrame(master=root, corner_radius= 0)
frame_lower_left.grid(row=1, column=0, sticky="nswe", padx=20, pady=20)

frame_lower_left.rowconfigure((0, 1, 3 , 4), weight=0)
frame_lower_left.columnconfigure((0, 1, 2, 3, 4, 5), weight=1)

def cb_state():
    print (str(radio_CB.get()))

    if radio_CB.get() == 1:
        print("radio is 1")
        for x in range(len(dc_ma1)):
            #print(dc_ma1)
            check_CB1[x].configure(state="normal")     
    else:
        print("radio is 0")    
        for x in range(len(dc_ma1)):
            #print(dc_ma1)
            check_CB1[x].configure(state="disabled")
            
frame_radio = customtkinter.CTkFrame(master=frame_lower_left)
frame_radio.grid(row=0, column=0, columnspan=6, pady=20, padx=20, sticky="nsew")
frame_cb = customtkinter.CTkFrame(master= frame_lower_left)
frame_cb.grid(row=1, column=0, columnspan = 6, pady=20, padx=20, sticky="nsew")
frame_cb.pack_forget()

frame_cb.grid_columnconfigure(4, minsize=10)   # empty row with minsize as spacing
frame_cb.columnconfigure(4, weight=1)


# radio button to Disable and disable CB
radio_CB = IntVar(value=0)
label_radio_group = customtkinter.CTkLabel(master=frame_radio, text="Combiner Box Configuration:")
label_radio_group.grid(row=0, column=0, pady=10, padx=10, sticky="w", columnspan = 5)

radio_button_1 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=0, command=cb_state, text= "Disable Checkbox")
radio_button_1.grid(row=0, column=10, pady=20, padx=10, sticky="w", columnspan = 5)
radio_button_2 = customtkinter.CTkRadioButton(master=frame_radio, variable=radio_CB, value=1, command=cb_state, text="Enable Checkbox")
radio_button_2.grid(row=0, column=20, pady=20, padx=10, sticky="w", columnspan = 5)


check_CB1 = {} 

for x in range(len(dc_ma1)):
    dc_ma1_l[x]=IntVar(0)
    #print(dc_ma1_l)
    
    y=dc_ma1_l[x]
            
    check_CB1[x] = customtkinter.CTkCheckBox(master= frame_cb, text="CB " + str(x+1), offvalue=0,onvalue=1, command=lambda x=dc_ma1[x],y=dc_ma1_l[x]:add_remove(x,y))
    check_CB1[x].grid(row=2, column=x, pady=10, padx=10, sticky="nsew")
    check_CB1[x].configure(state="disabled")

root.mainloop()
