-# NOTE: In order to minimize changes to Tkinter.py, some of the code here

-# As a result after creating a 'w = StdButtonBox', I can write

-"""Drag-and-drop support for Tkinter.
-
-This is very preliminary.  I currently only support dnd *within* one
-application, between different windows (or within the same window).
-
-I an trying to make this as generic as possible -- not dependent on
-the use of a particular widget or icon type, etc.  I also hope that
-this will work with Pmw.
-
-To enable an object to be dragged, you must create an event binding
-for it that starts the drag-and-drop process. Typically, you should
-bind <ButtonPress> to a callback function that you write. The function
-should call Tkdnd.dnd_start(source, event), where 'source' is the
-object to be dragged, and 'event' is the event that invoked the call
-(the argument to your callback function).  Even though this is a class
-instantiation, the returned instance should not be stored -- it will
-be kept alive automatically for the duration of the drag-and-drop.
-
-When a drag-and-drop is already in process for the Tk interpreter, the
-call is *ignored*; this normally averts starting multiple simultaneous
-dnd processes, e.g. because different button callbacks all
-dnd_start().
-
-The object is *not* necessarily a widget -- it can be any
-application-specific object that is meaningful to potential
-drag-and-drop targets.
-
-Potential drag-and-drop targets are discovered as follows.  Whenever
-the mouse moves, and at the start and end of a drag-and-drop move, the
-Tk widget directly under the mouse is inspected.  This is the target
-widget (not to be confused with the target object, yet to be
-determined).  If there is no target widget, there is no dnd target
-object.  If there is a target widget, and it has an attribute
-dnd_accept, this should be a function (or any callable object).  The
-function is called as dnd_accept(source, event), where 'source' is the
-object being dragged (the object passed to dnd_start() above), and
-'event' is the most recent event object (generally a <Motion> event;
-it can also be <ButtonPress> or <ButtonRelease>).  If the dnd_accept()
-function returns something other than None, this is the new dnd target
-object.  If dnd_accept() returns None, or if the target widget has no
-dnd_accept attribute, the target widget's parent is considered as the
-target widget, and the search for a target object is repeated from
-there.  If necessary, the search is repeated all the way up to the
-root widget.  If none of the target widgets can produce a target
-object, there is no target object (the target object is None).
-
-The target object thus produced, if any, is called the new target
-object.  It is compared with the old target object (or None, if there
-was no old target widget).  There are several cases ('source' is the
-source object, and 'event' is the most recent event object):
-
-- Both the old and new target objects are None.  Nothing happens.
-
-- The old and new target objects are the same object.  Its method
-dnd_motion(source, event) is called.
-
-- The old target object was None, and the new target object is not
-None.  The new target object's method dnd_enter(source, event) is
-called.
-
-- The new target object is None, and the old target object is not
-None.  The old target object's method dnd_leave(source, event) is
-called.
-
-- The old and new target objects differ and neither is None.  The old
-target object's method dnd_leave(source, event), and then the new
-target object's method dnd_enter(source, event) is called.
-
-Once this is done, the new target object replaces the old one, and the
-Tk mainloop proceeds.  The return value of the methods mentioned above
-is ignored; if they raise an exception, the normal exception handling
-mechanisms take over.
-
-The drag-and-drop processes can end in two ways: a final target object
-is selected, or no final target object is selected.  When a final
-target object is selected, it will always have been notified of the
-potential drop by a call to its dnd_enter() method, as described
-above, and possibly one or more calls to its dnd_motion() method; its
-dnd_leave() method has not been called since the last call to
-dnd_enter().  The target is notified of the drop by a call to its
-method dnd_commit(source, event).
-
-If no final target object is selected, and there was an old target
-object, its dnd_leave(source, event) method is called to complete the
-dnd sequence.
-
-Finally, the source object is notified that the drag-and-drop process
-is over, by a call to source.dnd_end(target, event), specifying either
-the selected target object, or None if no target object was selected.
-The source object can use this to implement the commit action; this is
-sometimes simpler than to do it in the target's dnd_commit().  The
-target's dnd_commit() method could then simply be aliased to
-dnd_leave().
-
-At any time during a dnd sequence, the application can cancel the
-sequence by calling the cancel() method on the object returned by
-dnd_start().  This will call dnd_leave() if a target is currently
-active; it will never call dnd_commit().

-"""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 Tkconstants 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)

-# pack_configure(), place_configure() and grid_columnconfigure(), and
-# forget() being short for pack_forget().  As a practical matter, I'm
-# afraid that there is too much code out there that may be using the
-# Pack, Place or Grid class, so I leave them intact -- but only as
-# backwards compatibility features.  Also note that those methods that
-# take a master as argument (e.g. pack_propagate) have been moved to
-# the Misc class (which now incorporates all methods common between
-# toplevel and interior widgets).  Again, for compatibility, these are
-# copied into the Pack, Place or Grid class.

-            Specifies that the size of the window cannot be made

-            for horizontal panedwindows, the y dimension for
-            vertical panedwindows. May be any value accepted by
-            Tk_GetPixels.

-            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.

-            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

-            stretched to fill the entire height (or width) of
-            its cavity.

-            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

-# LogoMation-like turtle graphics
-
-"""
-Turtle graphics is a popular way for introducing programming to
-kids. It was part of the original Logo programming language developed
-by Wally Feurzeig and Seymour Papert in 1966.
-
-Imagine a robotic turtle starting at (0, 0) in the x-y plane. Give it
-the command turtle.forward(15), and it moves (on-screen!) 15 pixels in
-the direction it is facing, drawing a line as it moves. Give it the
-command turtle.left(25), and it rotates in-place 25 degrees clockwise.
-
-By combining together these and similar commands, intricate shapes and
-pictures can easily be drawn.

-      Default is 50% of screen.
-    height: either the height in pixels or a fraction of the screen.
-      Default is 75% of screen.
-
-    Setting either width or height to None before drawing will force

-    startx: starting position in pixels from the left edge of the screen.
-      Default is to center window. Setting startx to None is the default

-
-    starty: starting position in pixels from the top edge of the screen.
-      Default is to center window. Setting starty to None is the default

-    >>> setup (width=200, height=200, startx=0, starty=0)
