Ferreteria/v0.5/menu

About

Menus in Ferreteria are static HTML which use URL data to convey state-changes. Many of the same classes and code are also used for isolated action-links which can be placed anywhere on a page, as appropriate (e.g. "[recalculate]", "[void]").

Changes from v0.4

The code for adding a menu entry to a section-header used to look like this:

        $oag = \fcHeaderMenuGroup::CreateCollection();
          $oag->ChoiceKey()->SetIt('do');
          $oag->BasePath()->SetIt($urlSelf);
          
          // create & configure settings for "edit" menu item
          $oa = \fcMenuOptionLink::CreateCollection();
            $oag->CopyValuesTo($oa);
            $oa->ChoiceValue()->SetIt('edit');
            $oa->Popup()->SetIt('edit this invoice');
            // create edit menu item object
            $ol = new \fcMenuOptionLink($oa);
            // add it to the menu group
            $oGrp->SetNode($ol);

          // create & configure settings for "empty the invoice" menu item
          $oa = \fcMenuOptionLink::CreateCollection();
            $oag->CopyValuesTo($oa);
            $oa->ChoiceValue()->SetIt('empty');
            $oa->Popup()->SetIt('remove all lines from this invoice');
            // create edit menu item object
            $ol = new \fcMenuOptionLink($oa);
            // add it to the menu group
            $oGrp->SetNode($ol);

The v0.5 methodology looks like this:

        $oMenu = caApp::Me()->GetHeaderMenu();
        // create & configure settings for "[add] => create new permission" menu item
          $ol = new \fcMenuOptionLink;
          $oa =  $ol->GetArgPod();
            $oa->BasePath()->SetIt($this->LinkURL());      // base URL to prefix all output URLs
            $oa->ChoiceKey()->SetIt('do');                 // name of option group to which this option belongs
            $oa->ChoiceValue()->SetIt('add');              // value of key for this action
            $oa->Popup()->SetIt('create new permission');  // (optional) hover-over text 	
          $doAdd = $ol->GetIsSelected();
          $oMenu->AddTwig($ol);

Changes:

• We now create the MenuOptionLink object directly, rather than spawning it using a static function.
• The function name for adding the Link to a parent object has changed from SetNode() to AddTwig().
  • In the v0.4 example, the parent is a Group object; in the v0.5 example, it's a HeaderMenu object.
