Instead of splitting a window, you can open one or more extra windows to show other parts of the workbook. Choose View Window New Window to open a new window on the active workbook. Excel distinguishes the windows by adding :1 to the name of the first and :2 to the name of the second for example, General Data:1 and General Data:2.

You added a new Model directory. It will do the heavy lifting, but you need the Block to handle the view component. \app\code\local\Definitivemagento\Helloworld\Model\Randomproducts.php < php class Definitivemagento_Helloworld_Model_Randomproducts extends Mage_Core_Model_Abstract { public function getRandomProducts($maxCount = 5) { $randProducts = array(); $allProducts = array(); $productCollection = Mage::getModel('catalog/product') ->getCollection() ->addAttributeToSelect('*') ->getItems(); foreach ($productCollection as $id => $data) { $allProducts[] = $data; } $productIds = array_keys($allProducts); $totalProductIds = count($productIds); for ($i=0; $i<$maxCount; $i++) { $randIndex = rand(0,$totalProductIds); $randProductId = $productIds[$randIndex]; $randProducts[] = $allProducts[$randProductId]; } return $randProducts; } } There s a lot going on here. Similar to the Block class, you go ahead and extend the base core Model. The purpose of this model is to fetch the random set of products and return that data to the Block. There are numerous ways to pull a list of products from your store. If you re old school, you can go straight SQL by reviewing its open schema (www.magentocommerce.com/wiki/development/magento_database_diagram). But the most flexible way is to use Magento s models: $productCollection = Mage::getModel('catalog/product') This line of code allows you to ask Magento for its catalog product model. A full list of available models and methods can be found on its massive documentation page (http://docs.magentocommerce.com/). Be warned; this is not for the faint of heart. Once you have obtained the model, go ahead and grab the collection: ->getCollection() Then set the MySQL Select query to return all columns: ->addAttributeToSelect('*')

Set by default, QWebSettings::AutoLoadImages specifies whether images in content should be automatically loaded. Set by default, QWebSettings::JavaScriptEnabled specifies whether JavaScript can be executed. QWebSettings::OfflineStorageDatabaseEnabled indicates whether HTML 5 offline data storage is permitted or not. QWebSettings::LocalStorageEnabled indicates whether HTML 5 local storage is enabled or not. QWebSettings::LocalContentCanAccessRemoteUrls indicates whether locally loaded documents are allowed to access remote URLs. The last property is especially handy; using it and locally cached content, you can restrict browsing to local content. QWebView relies heavily on its QWebPage object, which encapsulates the notion of a single web page. QWebPage, in turn, uses one or more QWebFrame objects to represent individual frames within the web page. You can obtain the QWebView s QWebPage instance by calling QWebView::page, and the main (parent) frame of a web page by calling QWebPage::mainFrame. QWebPage s API is similar to QWebView, because QWebView is really a widget implementation that delegates its handling of web content to QWebPage. A common use for QWebPage (aside from obtaining the page s main frame, something you do to embed Qt objects into the JavaScript runtime, which we discuss more in the next section) is to use it to render web content to an image. You do this using the QWebPage s render function, by invoking it when the web page finishes loading (when its loadFinished signal fires). Listing 5 3 shows pseudocode from a class to do this drawn from the QWebPage documentation.

Note Opening extra windows has two advantages over splitting a window. First, you can display other

worksheets (or workbooks) in the windows if you want rather than just other parts of the same worksheet. Second, you can zoom each window by a different amount as needed, or use a different view in each window.
