=head1 NAME
Demeter::UI::Wx::EchoArea - A run-time feedback widget
=head1 VERSION
This documentation refers to Demeter version 0.9.26.
=head1 SYNOPSIS
An echo area an be added to a Wx application:
my $echoarea = Demeter::UI::Wx::EchoArea->new($self);
$sizer -> Add($echoarea, 0, wxEXPAND|wxALL, 3);
The argument to the constructor method is a reference to the parent in
which this is placed. This is used as the echo area for all
Hephaestus utilities.
=head1 DESCRIPTION
This is derived from Wx::TextCrtl and is intended to serve as an echo
area in a Wx application in much the similar fashion as Emacs' echo
area.
=head1 METHODS
=over 4
=item C<echo>
Insert text into the echo area and push that text onto the echo buffer.
$echoarea->echo("Hi there!");
To clear the echo area without clearing the echo buffer, give this
method an empty string:
$echoarea->echo(q{});
This method returns the reference to the EchoArea widget.
=item C<buffer>
Return the contents of the echo buffer as an array.
@contents = $echoarea->buffer;
=item C<buffer_as_text>
Return the contents of the echo buffer as a simply formatted text string.
$contents = $echoarea->buffer_as_text;
=item C<Length>
Return the length of echo buffer.
$len = $echoarea->Length
=item C<clear>
Clear the echo area and empty the echo buffer.
$echoarea->clear;
This method returns the reference to the EchoArea widget.

=head1 CONFIGURATION
=head1 DEPENDENCIES
Demeter's dependencies are in the F<Build.PL> file.
=head1 BUGS AND LIMITATIONS
=over 4
=item *
Artemis & Athena will require a data entry mode. That could be done
by liftingt he readonly flag, changing the background color, and
grabbing focus until carriage return is pressed.
=item *
Need configurable text color and max length. Need warn and error
modes and configurable colors for those.
