=head1 DESCRIPTION |
41 |
|
|
|
42 |
|
|
This is the very first "true" Gtk2 widget written in Perl. |
43 |
|
|
|
44 |
|
|
The C<Gtk2::GoBoard> class works like any other widget, see the SYNOPSIS |
45 |
|
|
for short examples of the available methods, and the L<App::IGS> and |
46 |
|
|
L<KGS> modules for usage examples. |
47 |
|
|
|
48 |
|
|
Please supply a more descriptive description :) |

=head2 SOUND SUPPORT |
51 |
|
|
|
52 |
|
|
In addition to a graphical board widget, this module has some rudimentary |
53 |
|
|
support for sounds. |
54 |
|
|
|
55 |
|
|
Playing sounds required the L<Audio::Play> module. If it isn't installed, |
56 |
|
|
sounds will silently not being played. The module intentionally doesn't |
57 |
|
|
depend on L<Audio::Play> as it isn't actively maintained anymore and fails |
58 |
|
|
to install cleanly. |

|
|
This program should get you started. It creates a board with some |
726 |
|
|
markings, enables a cursor callback that shows a transparent black stone, |
727 |
|
|
and after a click, marks the position with a circle and disables the |
728 |
|
|
cursor. |
