使用标签将所选文本设置为粗体

您只需要

tag_add()

import Tkinter as tkdef make_bold():    aText.tag_add("bt", "sel.first", "sel.last")lord = tk.Tk()aText = tk.Text(lord, font=("Georgia", "12"))aText.grid()aButton = tk.Button(lord, text="bold", command=make_bold)aButton.grid()aText.tag_config("bt", font=("Georgia", "12", "bold"))lord.mainloop()

在一个完全无关的搜索中偶然发现了一个非常有教育意义的例子，莫过于Bryan

这是更动态替代方案的快速示例：

import Tkinter as tkimport tkFontdef make_bold():    current_tags = aText.tag_names("sel.first")    if "bt" in current_tags:        aText.tag_remove("bt", "sel.first", "sel.last")    else:        aText.tag_add("bt", "sel.first", "sel.last")lord = tk.Tk()aText = tk.Text(lord, font=("Georgia", "12"))aText.grid()aButton = tk.Button(lord, text="bold", command=make_bold)aButton.grid()bold_font = tkFont.Font(aText, aText.cget("font"))bold_font.configure(weight="bold")aText.tag_configure("bt", font=bold_font)lord.mainloop()
