因此,我有一个带有标题“ options”的Optionmenu和一些选项。每次我选择变量1时标题都会更改。更改后如何设置为字符串“ options”和变量的值? 例如:“选项-音乐关闭” 我试过了,但是没用:
variable1 = StringVar()
variable1.set("something",variable1)
谢谢。
编辑:这是我的代码的完整版本:
options = Menubutton(frame,textvariable = options3,indicatoron=True,borderwidth=1, relief="raised", width=20)
options.grid(row=3,column=2)#options2 [0] options3
main_menu = Menu(options,tearoff=False)
options.configure(menu=main_menu)
get_options3= options3.get()
neededstring = string+str(options3)
print("needed str", neededstring)
options3.set('options - ' +options3.get())
for item in (("Answer with text", "plain text", "only numbers", "only letters"),
("Answer with Checkbuttons", "red", "green", "blue"), ("Answer with Radiobuttons", "one option can be chosed")
):
menu = Menu(main_menu, tearoff=False)
main_menu.add_cascade(label=item[0], menu=menu)
for value in item[1:]:
menu.add_radiobutton(value=value, label=value, variable=options3)

如果您跟踪提供给OptionMenu的StringVar,则可以在更改选项时将字符串添加到最前面。这将创建一个带有OptionMenu的窗口,用于执行此操作:
import tkinter as tk
root = tk.Tk()
# function to add 'options - ' to the front of the selected option
def change_selected(var1):
var1.set('options - %s' % var1.get())
# variable
var1 = tk.StringVar(root)
var1.set('1')
# create menu
options = tk.OptionMenu(root, var1, '1', '2', '3')
options.pack()
# trace variable for changes
var1.trace('w', lambda *args: change_selected(var1))
root.mainloop()
