Re: gtk.TreeModel.iter_children() method, how often should it be called?

Hi.

I'm not sure about 1000, but calling this function a lot is normal if
you make major changes to your model while attached to GtkTreeView.

Try detaching model from tree view before doing any major change.
Sample code would look something like this (in C):
------------ CODE -----------
model = gtk_tree_view_get_model( GTK_TREE_VIEW( tree ) );
g_object_ref( G_OBJECT( model ) );
gtk_tree_view_set_model( GTK_TREE_VIEW( tree ), NULL );

/* Make changes */

gtk_tree_view_set_model( GTK_TREE_VIEW( tree ), model );
g_object_unref( G_OBJECT( model ) );
------------ /CODE -------------

Hope this helps.
