Re: GtkTreeview and interactive search for PHP-GTK v2.0

Thanks for your help kksou,
I modify your script :
- merge the two classes
- add a timeout
- add aparameter column
- As I had problem with class destructor, I used hide/show
- move all signal connexion into the class

$search_app = new Interactive_Search($treeview);

class Interactive_Search extends GtkWindow {

  protected $treeview; // the tree view
  protected $search_entry;
  protected $timeout_handler_delay = 3000; // autoclose the search window

  function __construct($treeview, $col = 0 ) {
    parent::__construct();
    $this->treeview = $treeview;

    $this->add($vbox = new GtkVBox());
    $this->set_modal(0);
    $this->set_decorated(0);
// I don't know if this is necessary
//     $this->set_parent_window($this->treeview->get_toplevel()->window);
    $this->set_transient_for($this->treeview->get_toplevel());

    $this->search_entry = new GtkEntry();
    $vbox->pack_start($frame = new GtkFrame(), 0);
    $frame->add($this->search_entry);

    $this->treeview->set_enable_search(false);
    $this->treeview->connect_simple('start-interactive-search',
array($this, 'start_interactive_search'));
    $this->treeview->connect('key-press-event', array($this,
'start_interactive_search'));
    $this->search_entry->connect('key-press-event', array($this,
'on_entry_keypress'));
    $this->search_entry->connect('focus-out-event', array($this,
'stop_interactive_search'));

    $this->treeview->set_search_entry($this->search_entry);
    $this->treeview->set_search_column($col);

  }

  public function start_interactive_search($treeview = null, $event = null){
    $this->show_all();

    // if start from treeview key_pressed
    if($event->string!=""){
      $this->search_entry->set_text($event->string);
      $this->search_entry->set_position(-1);
    }

    // Position of the search window
    $win_pos = $this->treeview->get_toplevel()->get_position();
    $x = $win_pos[0] + $this->treeview->allocation->width -
      $this->search_entry->allocation->width + $this->x_shift;
    $y = $win_pos[1] + $this->treeview->allocation->height +
      $this->treeview->allocation->y +
      $this->search_entry->allocation->height + $this->y_shift ;
    $this->move($x, $y);

    // Timeout signal connexion
    if($this->timeout_handler_id){
      Gtk::timeout_remove($this->timeout_handler_id);
    }
    $this->timeout_handler_id =
Gtk::timeout_add($this->timeout_handler_delay, array($this,
'stop_interactive_search'));
  }

  public function stop_interactive_search(){
    Gtk::timeout_remove($this->timeout_handler_id);
    $this->hide();
    return false;
  }

  public function on_entry_keypress($entry, $event) {
    if ($event->keyval==Gdk::KEY_Return ||
$event->keyval==Gdk::KEY_Escape) {
      $this->stop_interactive_search();
    } else {
      // Refresh timeout
      Gtk::timeout_remove($this->timeout_handler_id);
      $this->timeout_handler_id =
Gtk::timeout_add($this->timeout_handler_delay, array($this,
'stop_interactive_search'));
    }
    return false;
  }
}
