Sure. Though, if you want to use it for multiplatform, you'd have to have function like this:
void app::DisplayWebView(float x, float y, float width, float height)
{
#ifdef AGKWINDOWS
//Windows-native fuctions / library / anyhow you want to do it.
#endif
#ifdef AGKIOS
//How you do it on iOS.
#endif
#ifdef IDE_BLACKBERRY
//How you'd do it on blackberry playbook.
#endif
// And so on.
}
Quite possible. Though, I have no idea about opening a web view under ios / android / playbook (never needed one), you might be better with simply opening up browser application and giving it certain site to open. (Sadly, playbook's documentation is rather lacking, so it's hard to find instructions/tutorials for it)
