[Tkinter-discuss] python tcl mixed programming

[Jeff Epler]

This is the way I found to do it:
http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/lib/python/nf.py.in?rev=1.1

You're interested in the class 'Widgets' and the function 'makewidget'
which does all the work.

class Widgets:
    def __init__(self, master, *widgets):
        for (name, klass, path) in widgets:
            setattr(self, name, makewidget(master, klass, path))

def makewidget(master, klass, path):
    path = str(path)
    self = newinstance(klass)
    if path[0] == '.':
        if master._w == '.': self._name = path[1:]
        else: self._name = path[len(master._w)+1:]
        self._w = path
    else:
        self._name = path
        if master._w == '.': self._w = '.' + path
        else: self._w = master._w + '.' + path
    self.children = {}
    master.children[self._name] = self
    self.master = master
    self.tk = master.tk
    return self

Here's a use of the Widgets class:
    widgets = nf.Widgets(root_window, 
        ("help_window", Toplevel, ".keys"),
        ("about_window", Toplevel, ".about"),
        ("text", Text, pane_bottom + ".t.text"),
        ("preview_frame", Frame, pane_top + ".preview"),
        ...)
after this, it is possible to refer to widgets.help_window, widgets.text, etc.
