我正在使用 tkinter 制作 GUI。我希望某些小部件仅在选择某些参数时出现。我为此使用了 .pack_forget() 方法。但是,现在我有另一个问题。我在 OptionMenu 上设置了一个条件,根据用户的选择,它会显示为 ComboBox 还是 Entry。但是如果用户改变他的选择,我无法设法使两个小部件之一消失。
这是我的代码:
# Creation of Frame 4 #
Frame4 = tk.Frame(fenetre)
Frame4.pack(anchor = tk.NW, padx = 5, pady = 5)
# label4 creation #
label4 = tk.Label(Frame4, text = "what is the format?", font = ('Arial', '12'))
label4.pack(side = tk.LEFT)
# Création de la commande #
def Format_choice(self):
global Format
if choice.get() != Format:
Format = choice.get()
if Format == "CAPS Client":
# Création de la liste déroulante
Frame6.pack(anchor = tk.NW, padx = 5, pady = 5)
# NOMS is a list of strings
comboExample = ttk.Combobox(Frame6, textvariable = tk.StringVar(), values = NOMS, width = 45)
comboExample.current(0)
def callbackFunc(self):
global nom_site
nom_site = comboExample.get()
comboExample.bind("<<ComboboxSelected>>", callbackFunc)
comboExample.pack(side = tk.LEFT)
elif Format == "ETUDE":
Frame6.pack(anchor = tk.NW, padx = 5, pady = 5)
site = tk.StringVar()
def Name():
global nom_site
nom_site = site.get()
entrysite = tk.Entry(Frame6, textvariable = site)
entrysite.pack(side=tk.LEFT, padx=5, pady=5)
entrysite.focus_set()
valider = tk.Button(Frame6, text="Confirmer", command = Name, activeforeground = 'red')
valider.pack(side = tk.LEFT)
# Creation of choice#
choice = tk.StringVar()
choice.set("Default")
# Creation of the OptionMenu #
option4 = tk.OptionMenu(Frame4, choice, "Format1", "Format2", command = Format_choice)
option4.pack(side = tk.LEFT)
# Creation of Frame6
Frame6 = tk.Frame(fenetre)
# label6 creation
label6 = tk.Label(Frame6, text= "What is the name of the site ?", font = ('Arial', '12'))
label6.pack(side=tk.LEFT)
Frame6.pack_forget()
