[英]how to highlight the radio buttons one after the other in following code
如何在下面的代碼中高亮顯示單選按鈕?
以下代碼處於工作狀態,但我們無法自動突出顯示按鈕(掃描):
import tkinter as tk
root = tk.Tk()
v = tk.IntVar()
v.set(1) # initializing the choice, i.e. a
languages = [
("a",1),
("b",2),
("c",3),
("d",4),
("e",5)
]
def ShowChoice():
print(v.get())
tk.Label(root,
text="""Choose your favourite
programming language:""",
justify = tk.LEFT,
padx = 36).pack()
for val, language in enumerate(languages):
tk.Radiobutton(root,
text=language,
padx = 20,
variable=v,
command=ShowChoice,
value=val).pack(anchor=tk.W)
root.mainloop()
截圖:
將每個單選按鈕存儲到列表中...將其更改為
radios = []
r_config = {'padx':20, 'variable':v, 'command':ShowChoice}
for val, language in enumerate(languages):
radios.append(tk.Radiobutton(root, text=language,
value=val,**r_config))
radios[-1].pack(anchor=tk.W)
那么您可以稍后在更新方法中引用其配置
selected = -1
def color_tick():
global selected # ... ewww
radios[selected].config(bg=root.cget('bg'))
selected = (selected+1)%len(radios)
radios[selected].config(bg="yellow")
# schedule a new call in 1 second
root.after(1000,color_tick)
color_tick() # start the ticks
root.mainloop()
