更改tk选项菜单中单个单词的颜色？

Question

所以我抓住了一个网站上的事件链接，并将它们放入一个下拉菜单中进行选择。我的菜单代码：

import Tkinter as tk  
from Tkinter import StringVar 

selectMenu = tk.Tk() 


# #-> this is what I have 
# Followed by what you can use 


#var = Vars() 
#events = var.GetVars('Event') 
events = " " 
options = [] 
links = [] 
#forms = (driver.find_elements_by_class_name("with-cats")) #This is what I have 
forms = ["Yolo ","Dad? Closed","Anotha One","Normies! Closed"] #This is so you can try it for yourself 

for x in forms: 
    #info = x.text 
    info = x #Again, this is so you can try it for yourself 
    if events in info.lower(): 
     links.append(x) 

for link in range(0,len(links)): 
    #options.append(links[link].text) 
    options.append(links[link]) 
list(set(options)) 

selection = [] 
for link in range(0,len(options)): 
    selection.append(options[link]) 
select = StringVar(selectMenu) 
select.set("--None Selected--") 

menu = tk.OptionMenu(selectMenu, select, *(selection)) 

msg = "Which one would you like to attend?" 
label = tk.Label(selectMenu, text=msg, font="Helvedica 14") 

label.pack(side='top', pady=10) 
menu.pack(side="top", pady=10)  

selectMenu.attributes('-topmost', True) 
selectMenu.mainloop() 

所以此工程罚款和花花公子，但我想改善一下，以使其更明显的事件是开放的。为了澄清，发现一个事件被打开并放入菜单可能看起来像“这是一个很酷的事件”，但是一个被关闭的事件将被视为“这是一个很酷的事件已关闭”。我的目标是能够使前景变成红色，不管是Closed还是包含Closed的字符串（如果有可能的话）（我不确定是否可能，因为osx上的菜单和按钮通常默认为系统设置，也许有办法解决这个问题？）。

找到了解决方案！在MenuButton中使用Menu与Tkinter创建MenuOptions的方式相同，我可以创建一个自定义的MenuOption。如果您想添加更多选项，则可以使用menbutton.configure()选项编辑按钮，并使用menbutton.menu编辑菜单项。

import Tkinter as tk  
from Tkinter import Menu, Menubutton 

class Vars(): 

    global vari 
    vari = {} 

    def GetVars(self, var): 

     return vari.get(str(var)) 

    def SendVars(self, var, val): 

     vari[str(var)] = val 


class App(): 

    def buttselect(self, link, menbutton, selectMenu): 
     var = Vars() 
     var.SendVars("Selection", link) # Store selected event 
     menbutton.configure(text=link) # Set menu text to the selected event 

    def prnt(self, link): 
     var = Vars() 

     print var.GetVars("Selection") # Print event 

    def __init__(self, selectMenu): 
     events = " " 
     options = [] 
     links = [] 
     forms = ["Yolo ","Dad? Closed","Anotha One","Normies! Closed"] #This is so you can try it for yourself 

     menbutton = Menubutton (selectMenu, text="--None Selected--", relief="raised") 
     menbutton.grid() 
     menbutton.menu = Menu (menbutton, tearoff=0) 
     menbutton["menu"] = menbutton.menu 

     #Get a list of event names 
     for x in forms: 
      info = x #Again, this is so you can try it for yourself 
      #If desired event keyword is in an event name, add it to the correct links 
      if events in info.lower(): 
       links.append(x) 

     #Remove duplicates 
     for link in range(0,len(links)): 
      options.append(links[link]) 
     list(set(options)) 

     #Final list of event names turned into menu commands 
     for link in options: 

      if "Closed" in link: 
       menbutton.menu.add_command(label= link, command= lambda link=link: self.buttselect(link, menbutton, selectMenu), foreground='red') 
      else: 
       menbutton.menu.add_command(label= link, command= lambda link=link: self.buttselect(link, menbutton, selectMenu)) 

     b = tk.Button(selectMenu, text="Selection", command= lambda link=link: self.prnt(link)) #Print selected event 
     b.pack() 

     msg = "Which one would you like to attend?" 
     label = tk.Label(selectMenu, text=msg, font="Helvedica 14") 

     label.pack(side='top', pady=10) 
     menbutton.pack(side="top", pady=10)  


selectMenu = tk.Tk() 
selectMenu.attributes('-topmost', True) 
app = App(selectMenu) 
selectMenu.mainloop() 

这导致所希望的准确的结果：

据为OptionMenuhere和here我不认为文档有设置文本的颜色的方法。

您或许可以通过使用listBox来获得您想要的东西。有关listBox示例，请参阅文章here。
