Hi all.
I investigated the source, and as per
#####################################################
void
ev_view_find_set_highlight_search (EvView *view, gboolean
value)
{
view->highlight_find_results = value;
gtk_widget_queue_draw (GTK_WIDGET (view));
}
#####################################################
It does seem that "self._view.find_set_highlight_search(True)" SHOULD
enable the highlighting of searched-words.
It it true?
If yes, perhaps it could be an issue with the python-bindings?
