=head1 DESCRIPTION
|
|
|
|
GUI::HELPERS.pm is a library, containing some useful functions used by other
|
|

|
|
|
|
=head2 GUI::HELPERS::print_info($text, $ext);
|
|
|
|
=over 1
|
|

|
|
=head2 GUI::HELPERS::print_warning($text, $ext);
|
|
|
|
=over 1
|
|
|
|
is identically with GUI::HELPERS::print_warning(), only the
|
|
Gtk2::MessageDialog is of type warning.
|
|
|

=back
|
|
|
|
=head2 GUI::HELPERS::print_error($text, $ext);
|
|
|
|
=over 1
|
|
|
|
is identically with GUI::HELPERS::print_info(), only the Gtk2::MessageDialogog
|
|
is of type error and the program will shut down after closing the message.

|
|
|
=back
|
|
|
|
=head2 GUI::HELPERS::sort_clist($clist, $col);
|
|
|
|
=over 1
|
|
|
|
sorts the clist with the values from the given column $col.
|
|
|
|
=back
|

|
|
=head2 GUI::HELPERS::dialog_box($title, $text, $button1, $button2);
|
|
|
|
=over 1
|
|
|
|
returns the reference to a new window of type Gtk2::Dialog. $title and

|
$button1 must be given. $text and $button2 are optional arguments and can be
|
|
undef.
|
|
|
|
=back
|
|
|
|
=head2 GUI::HELPERS::create_label($text, $mode, $wrap, $bold);
|
|
|
|
=over 1
|
|

=head2 GUI::HELPERS::label_to_table($key, $val, $table, $row, $mode, $wrap, $bold);
|
|
|
|
=over 1
|
|
|
|
adds a new row to $table. The new row is appended at $row and has two columns:
|
|
the first will contain a label with the content of string $k, the second the
