ABOUT EASYGUI
EasyGui provides an easy-to-use interface for simple GUI interaction
with a user. It does not require the programmer to know anything about
tkinter, frames, widgets, callbacks or lambda. All GUI interactions are
invoked by simple function calls that return results.
@note:
WARNING about using EasyGui with IDLE
You may encounter problems using IDLE to run programs that use EasyGui. Try it
and find out. EasyGui is a collection of Tkinter routines that run their own
event loops. IDLE is also a Tkinter application, with its own event loop. The
two may conflict, with unpredictable results. If you find that you have
problems, try running your EasyGui program outside of IDLE.
Note that EasyGui requires Tk release 8.0 or greater.

A dialog to get a file name.
About the "default" argument
============================
The "default" argument specifies a filepath that (normally)
contains one or more wildcards.
fileopenbox will display only files that match the default filepath.
If omitted, defaults to "*" (all files in the current directory).
WINDOWS EXAMPLE::
...default="c:/myjunk/*.py"
will open in directory c:\myjunk\ and show all Python files.
WINDOWS EXAMPLE::
...default="c:/myjunk/test*.py"
will open in directory c:\myjunk\ and show all Python files
whose names begin with "test".
Note that on Windows, fileopenbox automatically changes the path
separator to the Windows path separator (backslash).
About the "filetypes" argument
==============================
If specified, it should contain a list of items,
where each item is either::
- a string containing a filemask # e.g. "*.txt"
- a list of strings, where all of the strings except the last one
are filemasks (each beginning with "*.",
such as "*.txt" for text files, "*.py" for Python files, etc.).
and the last string contains a filetype description
EXAMPLE::
filetypes = ["*.css", ["*.htm", "*.html", "HTML files"] ]
NOTE THAT
=========
If the filetypes list does not contain ("All files","*"),
it will be added.
If the filetypes list does not contain a filemask that includes
the extension of the "default" argument, it will be added.
For example, if default="*abc.py"
and no filetypes argument was specified, then
"*.py" will automatically be added to the filetypes argument.

========================================================================
0.96(2010-08-29)
========================================================================
This version fixes some problems with version independence.
BUG FIXES
------------------------------------------------------
* A statement with Python 2.x-style exception-handling syntax raised
a syntax error when running under Python 3.x.
Thanks to David Williams for reporting this problem.
* Under some circumstances, PIL was unable to display non-gif images
that it should have been able to display.
The cause appears to be non-version-independent import syntax.
PIL modules are now imported with a version-independent syntax.
Thanks to Horst Jens for reporting this problem.
LICENSE CHANGE
------------------------------------------------------
Starting with this version, EasyGui is licensed under what is generally known as
the "modified BSD license" (aka "revised BSD", "new BSD", "3-clause BSD").
This license is GPL-compatible but less restrictive than GPL.
Earlier versions were licensed under the Creative Commons Attribution License 2.0.
========================================================================
0.95(2010-06-12)
========================================================================
ENHANCEMENTS
------------------------------------------------------
* Previous versions of EasyGui could display only .gif image files using the
msgbox "image" argument. This version can now display all image-file formats
supported by PIL the Python Imaging Library) if PIL is installed.
If msgbox is asked to open a non-gif image file, it attempts to import
PIL and to use PIL to convert the image file to a displayable format.
If PIL cannot be imported (probably because PIL is not installed)
EasyGui displays an error message saying that PIL must be installed in order
to display the image file.
Note that
http://www.pythonware.com/products/pil/
says that PIL doesn't yet support Python 3.x.
========================================================================
0.94(2010-06-06)
========================================================================
ENHANCEMENTS
------------------------------------------------------
* The codebox and textbox functions now return the contents of the box, rather
than simply the name of the button ("Yes"). This makes it possible to use
codebox and textbox as data-entry widgets. A big "thank you!" to Dominic
Comtois for requesting this feature, patiently explaining his requirement,
and helping to discover the tkinter techniques to implement it.
NOTE THAT in theory this change breaks backward compatibility. But because
(in previous versions of EasyGui) the value returned by codebox and textbox
was meaningless, no application should have been checking it. So in actual
practice, this change should not break backward compatibility.
* Added support for SPACEBAR to command buttons. Now, when keyboard
focus is on a command button, a press of the SPACEBAR will act like
a press of the ENTER key; it will activate the command button.
* Added support for keyboard navigation with the arrow keys (up,down,left,right)
to the fields and buttons in enterbox, multenterbox and multpasswordbox,
and to the buttons in choicebox and all buttonboxes.
* added highlightthickness=2 to entry fields in multenterbox and
multpasswordbox. Now it is easier to tell which entry field has
keyboard focus.
BUG FIXES
------------------------------------------------------
* In EgStore, the pickle file is now opened with "rb" and "wb" rather than
with "r" and "w". This change is necessary for compatibility with Python 3+.
Thanks to Marshall Mattingly for reporting this problem and providing the fix.
* In integerbox, the actual argument names did not match the names described
in the docstring. Thanks to Daniel Zingaro of at University of Toronto for
reporting this problem.
* In integerbox, the "argLowerBound" and "argUpperBound" arguments have been
renamed to "lowerbound" and "upperbound" and the docstring has been corrected.
NOTE THAT THIS CHANGE TO THE ARGUMENT-NAMES BREAKS BACKWARD COMPATIBILITY.
If argLowerBound or argUpperBound are used, an AssertionError with an
explanatory error message is raised.
* In choicebox, the signature to choicebox incorrectly showed choicebox as
accepting a "buttons" argument. The signature has been fixed.
========================================================================
0.93(2009-07-07)
========================================================================
ENHANCEMENTS
------------------------------------------------------
* Added exceptionbox to display stack trace of exceptions
* modified names of some font-related constants to make it
easier to customize them
========================================================================
0.92(2009-06-22)
========================================================================
ENHANCEMENTS
------------------------------------------------------
* Added EgStore class to to provide basic easy-to-use persistence.
BUG FIXES
------------------------------------------------------
* Fixed a bug that was preventing Linux users from copying text out of
a textbox and a codebox. This was not a problem for Windows users.
