# A Python program implementing rmt, an application for remotely
# controlling other Tk applications.
# Cf. Ousterhout, Tcl and the Tk Toolkit, Figs. 27.5-8, pp. 273-276.

# Note that because of forward references in the original, we
# sometimes delay bindings until after the corresponding procedure is
# defined.  We also introduce names for some unnamed code blocks in
# the original because of restrictions on lambda forms in Python.

# XXX This should be written in a more Python-like style!!!

from Tkinter import *

# 1. Create basic application structure: menu bar on top of
# text widget, scrollbar on right.

root = Tk()
tk = root.tk
mBar = Frame(root, relief=RAISED, borderwidth=2)
mBar.pack(fill=X)

f = Frame(root)
f.pack(expand=1, fill=BOTH)
s = Scrollbar(f, relief=FLAT)
s.pack(side=RIGHT, fill=Y)
t = Text(f, relief=RAISED, borderwidth=2, yscrollcommand=s.set, setgrid=1)

t.tag_config('bold', font='-Adobe-Courier-Bold-R-Normal-*-120-*')
s['command'] = t.yview

root.title('Tk Remote Controller')
root.iconname('Tk Remote')

# 2. Create menu button and menus.

                   menu=file_m_apps)
file_m.add_command(label='Quit', underline=0, command=sys.exit)

# 3. Create bindings for text widget to allow commands to be
# entered and information to be selected.  New characters
# can only be added at the end of the text (can't ever move
# insertion point).

def single1(e):
    x = e.x
    y = e.y
    t.setvar('tk_priv(selectMode)', 'char')

t.bind('<Control-v>', controlv)

# 4. Procedure to backspace over one character, as long as
# the character isn't part of the prompt.

def backspace(e):
    if t.index('promptEnd') != t.index('insert - 1 char'):
        t.delete('insert - 1 char', AtInsert())
        t.yview_pickplace(AtInsert())
t.bind('<BackSpace>', backspace)
t.bind('<Control-h>', backspace)
t.bind('<Delete>', backspace)

# 5. Procedure that's invoked when return is typed:  if
# there's not yet a complete command (e.g. braces are open)
# then do nothing.  Otherwise, execute command (locally or
# remotely), output the result or error message, and issue
# a new prompt.

def invoke():

def prompt():
    t.insert(AtInsert(), app + ': ')
    t.mark_set('promptEnd', 'insert - 1 char')
    t.tag_add('bold', 'insert linestart', 'promptEnd')

# 6. Procedure to select a new application.  Also changes
# the prompt on the current command line to reflect the new
# name.

def newApp(appName):
    global app
    app = appName
    t.delete('promptEnd linestart', 'promptEnd')
    t.insert('promptEnd', appName + ':')
    t.tag_add('bold', 'promptEnd linestart', 'promptEnd')

def fillAppsMenu():
    file_m_apps.add('command')
    file_m_apps.delete(0, 'last')
    names = root.winfo_interps()
    names = list(names)
