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
