"""Wrapper functions for Tcl/Tk.

Tkinter provides classes which allow the display, positioning and
control of widgets. Toplevel widgets are Tk and Toplevel. Other
widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,
Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox
LabelFrame and PanedWindow.

Properties of the widgets are specified with keyword arguments.
Keyword arguments have the same name as the corresponding resource
under Tk.

Widgets are positioned with one of the geometry managers Place, Pack
or Grid. These managers can be called with methods place, pack, grid
available in every Widget.

Actions are bound to events by resources (e.g. keyword argument
command) or with the method bind.

Example (Hello, World):
import tkinter
from tkinter.constants import *
tk = tkinter.Tk()
frame = tkinter.Frame(tk, relief=RIDGE, borderwidth=2)
frame.pack(fill=BOTH,expand=1)
label = tkinter.Label(frame, text="Hello, World")
label.pack(fill=X, expand=1)
button = tkinter.Button(frame,text="Exit",command=tk.destroy)
button.pack(side=BOTTOM)
tk.mainloop()

        before window
            Insert the window before the window specified. window
            should be the name of a window already managed by pathName.

            Specify a height for the window. The height will be the
            outer dimension of the window including its border, if
            any. If size is an empty string, or if -height is not
            specified, then the height requested internally by the

            adjusted by the movement of sashes in the panedwindow.
            Size may be any value accepted by Tk_GetPixels.
        minsize n
            Specifies that the size of the window cannot be made
            less than n. This constraint only affects the size of
            the widget in the paned dimension -- the x dimension
            for horizontal panedwindows, the y dimension for
            vertical panedwindows. May be any value accepted by

        padx n
            Specifies a non-negative value indicating how much
            extra space to leave on each side of the window in
            the X-direction. The value may have any of the forms
            accepted by Tk_GetPixels.
        pady n
            Specifies a non-negative value indicating how much
            extra space to leave on each side of the window in
            the Y-direction. The value may have any of the forms
            accepted by Tk_GetPixels.
        sticky style
            If a window's pane is larger than the requested
            dimensions of the window, this option may be used
            to position (or stretch) the window within its pane.
            Style is a string that contains zero or more of the
            characters n, s, e or w. The string can optionally
            contains spaces or commas, but they are ignored. Each
            letter refers to a side (north, south, east, or west)
            that the window will "stick" to. If both n and s
            (or e and w) are specified, the window will be
            stretched to fill the entire height (or width) of
            its cavity.
        width size
            Specify a width for the window. The width will be
            the outer dimension of the window including its
            border, if any. If size is an empty string, or
            if -width is not specified, then the width requested
            internally by the window will be used initially; the
            width may later be adjusted by the movement of sashes
            in the panedwindow. Size may be any value accepted by
