This widget also serves as an example implementation using the Gtk2::Ex::PopupWindow
module.
=head1 SYNOPSIS
use Glib qw(TRUE FALSE);
use Gtk2 qw/-init/;
use Gtk2::Ex::ComboBox;
my $button = Gtk2::Button->new('click me');
my $combobox = Gtk2::Ex::ComboBox->new($button);
# Or you can call the constructor with two arguments
# my $combobox = Gtk2::Ex::ComboBox->new($button, 'no-checkbox' );
$combobox->set_list(['this', 'that', 'what']);
$button->signal_connect('button-release-event' => sub { $combobox->show; } );
=head1 METHODS
=head2 new($parent, <$type>);
The C<$parent> refers to the widget to which the ComboBox is attached.
The C<$type> parameter is optional. It can be of one of the three types
'with-buttons' (this is the default option if none specified)
'with-checkbox'
'no-checkbox'
These three types control the way the user selects the multiple entries.
Please refer to the C<examples/combobox.pl> for a demonstration.
=head2 set_list([$list]);
The list of choices is entered using this method. Accepts an array (of strings)
as the argument.
$combobox->set_list(['this', 'that', 'what']);
=head2 set_list_preselected([$list]);
The list of choices is entered using this method. Accepts an array of arrays
as the argument. Each element array should have a boolean and a string.
The boolean denotes whether this element should be marked as selected or not.
$combobox->set_list([[0,'this'], [1,'that'], [1,'what']]);
In the example shown above, the elements C<'that'> and C<'what'> will be marked
as I<selected> in the dropdown list.
=head2 get_treeview;
Returns the treeview that serves as the model for the ComboBox. This widget
internally uses Gtk2::Ex::Simple::List and therefore the return object will
be of that class.
lib/Gtk2/Ex/ComboBox.pm view on Meta::CPAN
as I<selected>.
C<$hash{'unselected-indices'}> contains a list of all the indices that are B<not>
marked as I<selected>.
=head2 show;
Call this method to display the ComboBox. Typically on a C<'button-release-event'>
on the parent widget.
$button->signal_connect('button-release-event' => sub { $combobox->show; } );
=head2 hide;
Call this method to hide the ComboBox. This method does not have to be called
explicitly since the ComboBox is automatically closed if the user clicks anywhere
outside.
=head1 SIGNALS
C<changed> - This signal gets emitted whenever the selection is changed.
$combobox1->signal_connect('changed' =>
sub {
print "combobox1 selection changed\n";
}
);
