I have a custom TreeView in which I want to implement both a filter and sorting
functionality. Unfortunately Gtk2::TreeStore does not implement
Gtk2::TreeModelFilter. Currently, I get around this by overriding the following
routine in my custom TreeView.
sub set_model
{
my ($self, $model) = @_;
$self->{model} = $model;
$self->{filter_model} = Gtk2::TreeModelFilter->new($model);
$self->{filter_model}->set_visible_func(\&_visible_func, $self);
$self->{sort_model} = Gtk2::TreeModelSort->new($self->{filter_model});
$self->Gtk2::TreeView::set_model($self->{sort_model});
}
I would like to create a custom model so I don't need to use this hack. I have
looked around for information on this - but it is sparse - and that I do find
is not all that informative. Does anyone know of a resource that I can use to
learn how to do this?
