Creating a bulleted list on a label widget using python tkinter

Question

Is there any way to create a hanging indented list using the tkinter label widget? Note: Using propper standard bullets not * or -.

Answer 1

you can use unicode code points, as a rough implementation:

try:
    import tkinter as tk
except ImportError:
    import Tkinter as tk

class BulletLabel(tk.Label):
    def __init__(self, master, *args, **kwargs):
        text = kwargs.pop('text', '')
        kwargs['text'] = self.bulletise(text)
        tk.Label.__init__(self, master, *args, **kwargs)

    def bulletise(self, text):
        if len(text) == 0: # no text so no bullets
            return ''
        lines = text.split('\n')
        parts = []
        for line in lines: # for each line
            parts.extend(['\u2022', line, '\n']) # prepend bullet and re append newline removed by split
        return ''.join(parts)

    def configure(self, *args, **kwargs):
        text = kwargs.pop('text', '')
        if text != '':
            kwargs['text'] = self.bulletise(text)
        tk.Label.configure(*args, **kwargs)


root = tk.Tk()

blabel = BulletLabel(root, text='one\ntwo\nthree')
blabel.pack()

root.mainloop()
