=head1 NAME
Tk::NumEntry - A numeric Entry widget with inc. & dec. Buttons
=head1 SYNOPSIS
S< >B<use Tk::NumEntry;>
S< >I<$parent>-E<gt>B<NumEntry>(?I<-option>=E<gt>I<value>, ...?);
=head1 DESCRIPTION
B<Tk::NumEntry> defines a widget for entering integer numbers. The widget
also contains buttons for increment and decrement.
B<Tk::NumEntry> supports all the options and methods that the plain
NumEntry widget provides (see L<Tk::NumEntryPlain>), plus the
following options
=head1 STANDARD OPTIONS
Besides the standard options of the L<Entry|Tk::Entry> widget
NumEntry supports:
B<-orient> B<-repeatdelay> B<-repeatinterval>
The B<-orient> option specifies the packing order of the increment and
decrement buttons. This option can only be set at creation time.
=head1 WIDGET-SPECIFIC OPTIONS
=over 4
=item Name: B<buttons>
=item Class: B<Buttons>
=item Switch: B<-buttons>
=item Fallback: B<1>
Boolean that defines if the inc and dec buttons are visible.
=item Switch: B<-readonly>
=item Fallback: B<0>
If B<-readonly> is set to a true value, then the value can only be
changed by pressing the increment/decrement buttons. This option can
only be set at creation time.
=back
=head1 WIDGET METHODS
Subclasses of NumEntry may override the following methods to use
different widgets for the composition of the NumEntry. These are:
NumEntryPlainWidget (usually C<NumEntryPlain>), FireButtonWidget
(usually C<FireButton>, IncFireButtonWidget and DecFireButtonWidget.
FireButtonWidget is used if IncFireButtonWidget or DecFireButtonWidget
are not defined.

=head1 ACKNOWLEDGEMENTS
I would to thank Achim Bohnet <F<ach@mpe.mpg.de>>
for all the feedback and testing. And for the splitting of the original
Tk::NumEntry into Tk::FireButton, Tk::NumEntryPlain and Tk::NumEntry
