How can you stop screen rotation on a Playbook using PhoneGap?

Question

I've found solutions to this for iOS and Android, but I can't find one for the Playbook. Is there a way to use PhoneGap or Zepto to lock the screen into portrait orientation on Playbook, and if so, how?

I've tried using the command <preference name="orientation" value="portrait" /> in config.xml, but it had no effect.

You can achieve it by following steps, if you are using Web Works SDK.

1. Browse to the "device_templates" directory of BlackBerry WebWorks SDK. This directory is typically found in "[DRIVE]:\InstallDir\BlackBerry WebWorks Packager\device_templates"

2. Open the "Widget.java" file found in this directory in a text

   editor.

3. Make the below changes in the Widget.java file. The
   //MODIFIED CODE indicates the changes done

   public Widget(WidgetConfig wConfig) {

               _wConfig = wConfig;
               initialize();
   
               int directions = net.rim.device.api.system.Display.DIRECTION_PORTRAIT;    net.rim.device.api.ui.Ui.getUiEngineInstance().setAcceptableDirections(directions);
   
               // Create PageManager
               PageManager pageManager = new PageManager(this, (WidgetConfigImpl) _wConfig);
   
               // push screen
               WidgetScreen wScreen = new BrowserFieldScreen(this, pageManager);
               pageManager.pushScreens((BrowserFieldScreen)wScreen);
           }
