Re: error in constructor

I imagine the constructor is called twice, because when you call $toto = new ProjectList() ProjectList::__construct() is called and so GtkTreeview::__construct(), then ProjectList::ProjectList() because it exists. In my opinion, if you just need to set the model use set_model() instead of calling the prent constructor. Hope this helps, Benjamin. Le 31/08/2009 19:07, Der Starchaser a écrit :

I want to program a class ProjectList, which is derived from class GtkTreeView. The following code snippet results in an assertion error. Is anybody able to explain me the error ? class ProjectList extends GtkTreeView {

     protected $store;

     /***********************************************************/
     /* Constructor Method
     /***********************************************************/
     function ProjectList()
     {

         $this->store = new GtkListStore(
        GObject::TYPE_STRING, GObject::TYPE_STRING
    );

         parent::__construct( $this->store );

                 $col = 0;
                 $column = $this->get_column(0);
                 assert( $column );        //<- this line throws an assertion error
                 $cell_renderer = new GtkCellRendererPixbuf();
                 $column->pack_start($cell_renderer, false);

        $column->set_cell_data_func(
            $cell_renderer,
            "prjlist_format_pixbuf",
            $this->Pixmap
        );

     }

} // of class

ugh - if you want to override the constructor that's fine - do it using public function __construct() {} PHP 5 uses unified constructors - the "use the same function as the class name" support is a holdover for BC, please please don't use it in new code.... as you see it has some seriously odd side effects see the manual http://php.net/oop5.decon Thanks, Elizabeth
