定义双击文本小部件时选择的字符

问题描述

在 Windows 上，双击文本小部件中的单词也将选择连接的标点符号.
有什么办法可以定义你想被选中的字符吗?

On Windows, double clicking a word in a Text widget will also select connected punctuation.
Is there any way to define the characters that you want to be selected?

推荐答案

以下是 Python 3.4 的示例:

Here is an example for Python 3.4:

import tkinter

class Creator(object):

    def __init__(self):

        root = self.root = tkinter.Tk()

        # Main Frame
        f_main = tkinter.Frame(root, borderwidth=6, relief='flat')
        f_main.grid(row=0, column=0, sticky='nsew')

        # Text widget and frame
        f_txt = tkinter.Frame(f_main, borderwidth=2, relief="sunken")
        f_txt.config(width=768, height=768)
        f_txt.pack(padx=4, pady=4, side="bottom", fill="both", expand=True)

        my_txt = self.text = tkinter.Text(f_txt)
        my_txt.config(undo=True, wrap='word')
        my_txt.grid(row=0, column=0, sticky="nsew")
        my_txt.focus_set()

GUI = Creator()
GUI.root.tk.eval("catch {tcl_endOfWord}")
GUI.root.tk.eval("catch {tcl_startOfPreviousWord}")
GUI.root.tk.eval("set tcl_wordchars {[[:alnum:]']}")
GUI.root.tk.eval("set tcl_nonwordchars {[^[:alnum:]']}")
GUI.root.mainloop()

来自 http://wiki.tcl.tk/1655 的注释:

...要更改有效的字符，您必须首先执行类似:

抓住{tcl_endOfWord}

catch {tcl_endOfWord}

可以在这里研究正则表达式语法:https://www.tcl.tk/man/tcl8.6/TclCmd/re_syntax.htm
