Handle back key event in Cocos2dx 2.2.2 Windows Phone 8 XAML and C++

Cocos2d-x-2.2.2 version has introduced new project template based on XAML and C++ Component  for Windows Phone 8 platform which allows you to develop games with C# and C++ mixed. You can use XAML components using this template but it's missing BACK key event handling which is primary key for Windows Phone application navigation. However there is a work around which allows you to handle BACK key in your C++ Component based game.

Open CocosRenderer.cpp and change the OnBackKeyPress() method as following:

bool Cocos2dRenderer::OnBackKeyPress()
{
    //return false;
    CCDirector::sharedDirector()->getKeypadDispatcher()->dispatchKeypadMSG(kTypeBackClicked);
    return true;
}


You can override virtual void keyBackClicked();  method in your Game Layer and handle back key event.
