Question

我想显示一个弹出消息框的方式，但不显示两个选项（是，否），我想个性化两个以上的选项，例如，我想问问他最好的颜色（蓝色，红色），绿色）：

import tkinter.messagebox
from tkinter import Button, Tk


def ask_multiple_choice_question():
    answer = tkinter.messagebox.askquestion(
        "colors", "whats your favorite color"
    )  # red, blue, green
    print(answer)  # print the color chosen


window = Tk()

Button(text="Submit", command=ask_multiple_choice_question).pack()
window.mainloop()

Answer 1

没有内置选项，但可以构造一个。

from tkinter import *
from tkinter import messagebox

class OptionDialog(Toplevel):
    """
        This dialog accepts a list of options.
        If an option is selected, the results property is to that option value
        If the box is closed, the results property is set to zero
    """
    def __init__(self,parent,title,question,options):
        Toplevel.__init__(self,parent)
        self.title(title)
        self.question = question
        self.transient(parent)
        self.protocol("WM_DELETE_WINDOW",self.cancel)
        self.options = options
        self.result = '_'
        self.createWidgets()
        self.grab_set()
        ## wait.window ensures that calling function waits for the window to
        ## close before the result is returned.
        self.wait_window()
    def createWidgets(self):
        frmQuestion = Frame(self)
        Label(frmQuestion,text=self.question).grid()
        frmQuestion.grid(row=1)
        frmButtons = Frame(self)
        frmButtons.grid(row=2)
        column = 0
        for option in self.options:
            btn = Button(frmButtons,text=option,command=lambda x=option:self.setOption(x))
            btn.grid(column=column,row=0)
            column += 1 
    def setOption(self,optionSelected):
        self.result = optionSelected
        self.destroy()
    def cancel(self):
        self.result = None
        self.destroy()



if __name__ == '__main__':
    #test the dialog
    root=Tk()
    def run():
        values = ['Red','Green','Blue','Yellow']
        dlg = OptionDialog(root,'TestDialog',"Select a color",values)
        print(dlg.result)
    Button(root,text='Dialog',command=run).pack()
    root.mainloop()

评论：我需要更优雅的方式

您正在寻找这样的东西：

class App(Application):
    def __init__(self):
        super().__init__()

        for question in questions:
            question.choice = Dialog.ask_multiple_choice(self, question)


if __name__ == "__main__":
    App().mainloop()

有没有办法像消息框一样在弹出窗口中要求多个选择
