在两栏中设置tkinter消息框中文本的格式

Question

通常，我在控制台中使用固定长度的字符格式化文本。现在我想在tkinter消息框中做一些类似的事情，但这会弄乱缩进。举个例子

from tkinter import messagebox

    info = {'Everything': 'first one', 'should be': 'second one', 'evenly outlined': 'another one', 'ms are really long':'previous to the last', 'mmmmmmmmmmmmmmm': "you see?"}
    infostring = (f"{k: <20}:{v}" for k, v in info.items())
    messagebox.askokcancel(
        title="outlining",
        icon=messagebox.QUESTION,
        message=("Is this your outlined well?\n\n" + "\n".join(infostring)),
    )

结果：

而在控制台中，它将是：

Everything          :first one
should be           :second one
evenly outlined     :another one
ms are really long  :previous to the last
mmmmmmmmmmmmmmm     :you see?

这就是我想在信箱里看到的。

由于操作系统级别的限制，我认为使用普通的MessageBox是不可能的。但是，您可以通过将justify设置为tkinter.LEFT在标签中执行此操作。

下面是一些示例代码：

import tkinter
msg = """Everything          :first one
should be           :second one
evenly outlined     :another one
ms are really long  :previous to the last
mmmmmmmmmmmmmmm     :you see?"""
r = tkinter.Tk()

label1 = tkinter.Label(r, text=msg, font=("Consolas", 12), justify=tkinter.LEFT)
label1.place(x=0,y=0)
r.mainloop()

它输出以下内容：

我承认这不是一个确切的答案，我也不是非常精通Tkinter，但希望这能提供一些帮助。祝好运!

编辑：

我还使用了等宽字体，这很可能是为了确保文本始终具有一致的宽度所必需的。

您可以使用simpledialog模块并自己构建一个。

from tkinter import *
from tkinter import simpledialog

class Dialog(simpledialog.Dialog):
    def __init__(self,master,title=None):
        root.bell()
        simpledialog.Dialog.__init__(self,master,title)

    def body(self,frame):
        icon_label=Label(frame,image='::tk::icons::question')
        icon_label.pack(side='left',anchor='n',padx=(0,10))
        label=Label(frame,text="Is this your outlined well?\n\n" + "\n".join(infostring),
            justify='left',font='Consolas 11')
        label.pack(side='right')
        return label

def dialog():
    Dialog(root,title='outlining')

root=Tk()

info = {'Everything': 'first one', 'should be': 'second one', 'evenly outlined': 'another one',
    'ms are really long':'previous to the last', 'mmmmmmmmmmmmmmm': "you see?"}
infostring = (f"{k: <20}:{v}" for k, v in info.items())

button=Button(root,text='Dialog',command=dialog)
button.pack(padx=100,pady=100)

root.mainloop()

您还可以对Dialog类进行以下更改，使其看起来更接近本机类。

def body(self,frame):
    frame.config(bg='white')
    frame.master.config(bg=frame['bg'])
    icon_label=Label(frame,image='::tk::icons::question',bg=frame['bg'])
    icon_label.pack(side='left',anchor='n',padx=(0,10))
    label=Label(frame,text="Is this your outlined well?\n\n" + "\n".join(infostring),
        justify='left',font='Consolas 11',bg=frame['bg'])
    label.pack(side='right')
    return label

def buttonbox(self):

    box = Frame(self)

    w = ttk.Button(box, text="Cancel", width=10, command=self.cancel)
    w.pack(side=RIGHT, padx=5, pady=5)
    w = ttk.Button(box, text="OK", width=10, command=self.ok, default=ACTIVE)
    w.pack(side=RIGHT, padx=5, pady=5)

    self.bind("<Return>", self.ok)
    self.bind("<Escape>", self.cancel)

    box.pack(fill='x')
