Glib::Ex::ConnectProperties::Element::tree_selection -- TreeSelection rows
Glib::Ex::ConnectProperties->new([$treesel, 'tree-selection#width'], [$another, 'something']);
This element class implements ConnectProperties access to rows selected in a Gtk2::TreeSelection.
tree-selection#empty boolean, read-only tree-selection#not-empty boolean, read-only tree-selection#count integer, read-only tree-selection#selected-path Gtk2::TreePath or undef
Gtk2::TreeSelection is normally used by
Gtk2::TreeView. The target object for ConnectProperties should be the TreeSelection, as obtained from the TreeView with
$treeselection = $treeview->get_selection();
tree-selection#not-empty might be connected up to make a delete button sensitive only when the user has selected one or more rows,
my $treeselection = $treeview->get_selection; Glib::Ex::ConnectProperties->new ([$treeselection, 'tree-selection#not-empty'], [$button, 'sensitive', write_only => 1]);
tree-selection#selected-path is the first selected row. It's intended for use with "single" selection mode so there's at most one row selected. Writing to the property does
select_path() and in single mode will switch from any existing selected row to just the new one. This could be used to synchronise the selected item in two TreeViews.
Rows in a
Gtk2::TreeSelection and items in a
Gtk2::IconView are similar but not quite the same and so are kept as separate
For reference a
selected-iter of type
Gtk2::TreeIter might mostly work, but not sure about comparing on storing. Would prefer an
compare() method on
Gtk2::TreeIter rather than going via the model. (Perl-Gtk2's
to_arrayref() access only suits Perl code models.)
