[Fernando Correa da Conceição-3]

I have a GtkTreeView which show a tree o files. How can I remove all
childs of a node? Or I have to get each one of then and remove?

Thanks!

Hi Fernando,

You'll laugh when you see the solution. It's a one-liner unset($model[$iter]).

The complete sample code here:
http://www.kksou.com/php-gtk2/articles/remove-nodes-from-GtkTreeView---Part-1.php

It make use the GtkTreeModel functionality implemented by Andrei:

Thanks, but this is not exacty what I need, but I can use it as an
example. And about the post you refer from Andrei, it is very usefull
thing but is not on the manual, I will write some docs using it and add
to the manual as a tutorial. My case is that I do not want remove the
parent node, only the childs.

Try this then...

$parent_node = $model[$iter];
$nodes_to_remove = array();

foreach ($parent_node->children() as $child_node) {
    $iter = $child_node->iter;
    $nodes_to_remove[] = $model->get_string_from_iter($iter);
}

for ($i=count($nodes_to_remove)-1; $i>=0; --$i) {
    unset($model[$nodes_to_remove[$i]]);
}
