Re: [Visualpython-users] Text entry

[Bruce S. <Bru...@nc...>]

There isn't a true text-editing object in VPython. The closest
approximation is this routine found in the documentation on keyboard
events:

from visual import *
prose = label() # initially blank text
while True:
    if scene.kb.keys: # event waiting to be processed?
        s = scene.kb.getkey() # get keyboard info
        if len(s) == 1:
            prose.text += s # append new character
        elif ((s == 'backspace' or s == 'delete') and
                len(prose.text)) > 0:
            prose.text = prose.text[:-1] # erase letter
        elif s == 'shift+delete':
            prose.text = '' # erase all text

Of course there is also the ability to use Python to accept input that
appears in the Python Shell window.
