GtkTreeview and interactive search

[Benjamin FOURTICQ]

Seems that interactive search doesn't work since I upgrade to new
version. Can anybody give me an example ?

my example that doesn't work :
<?php
$window = new GtkWindow();
$window->set_size_request(400, 200);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());

$sc = new GtkScrolledWindow();
$vbox->add($sc);

$model = new GtkListStore(GObject::TYPE_LONG);
for($i=10; $i < 20; $i++){
  $model->append(array($i));
 }

$view = new GtkTreeView($model);
$view->append_column(new GtkTreeViewColumn( "", new
GtkCellRendererText(), 'text', 0));
$sc->add($view);

//$view->set_enable_search(1);
$view->set_search_column(0);
$window->show_all();

Gtk::main();
?>

Thanks in advance,
Benjamin.

Hi Benjamin,

I think the bug lies in the gtk+v2.12 and not PHP-GTK.

While we wait for the bug to be fixed, Carl recently posted a very interesting work-around here:
http://www.kksou.com/php-gtk2/PHP-GTK2-Help/248-ReGtkTreeView-search-on-windows/Page-2/Page-2.php#248

I built on his idea to come out with a complete sample code for interactive search on GtkTreeView:

Hope it helps.

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;
  }
}

Hi Benjamin,

Just a little suggestion. In your code, you have used:

protected $timeout_handler_delay = 3000;
$this->timeout_handler_id =
Gtk::timeout_add($this->timeout_handler_delay, array($this,
'stop_interactive_search'));

Imagine a user typing slowly. At the end of 3 seconds, the search box will automatically hide, even though he is still typing halfway.

So you might want to change the code slightly so that each mouse or button activity in the search field will reset the start time of inactivity.

Here's a sample code for your reference:
