[Tkinter-discuss] putting a series of hyperlinks in a text widget

[Michael O'Donnell]

Dear Alex,

    I think you are on to a valid solution: tag each anchor.

I would use 2 tags:

1) A general tag called for example 'link', which you config
    a) to present itself as a link (e.g., in blue, underlines)
    b) to respond to events, e.g., ButtonRelease

2) a tag for each individual link, which could be an integer
indicating which link it is (e.g., the position of the url in a list
of  urls).

When you insert the text of the anchor in the widget, specify: ('link', str(i))

The action bound to the ButtonRelease event can recover which link was pressed,
and recover the appropriate url to follow.

E.g.

from Tkinter import *
master = Tk()

LINKS=("http://www.python.org", "http://www.heaven.com")

def showLink(event):
    idx= int(event.widget.tag_names(CURRENT)[1])
    print LINKS[idx]

txt=Text(master)
txt.pack(expand=True, fill="both")
txt.insert(END, "Press ")
txt.insert(END, "here ", ('link', str(0)))
txt.insert(END, "for Python. Press ")
txt.insert(END, "here ", ('link', str(1)))
txt.insert(END, "for Heaven.")
txt.tag_config('link', foreground="blue")
txt.tag_bind('link', '<Button-1>', showLink)

master.mainloop()
