c++ - boost::Variant usage -

I am developing the GMI application through wxWidgets. It has 2 parts - GUI part and "Logic" portion. I want to be completely independent on the rigid part wxWidgets. But a component in the GUI is returning to the wxVariant and I need to use it in the logic part.

Therefore, to promote the "convertible" type :: Variable

The work of wxVariant works like this:

  wxVariant v ("37 "); Int i = v.GetInteger (); // i == 37    So I'm thinking like something  
  string s = methodReturningWxVariant (). GetString (); Promotion: Version BV (S); // Code later eg BV.GetInt (); BV.GetBool ();    Is it possible to use this promotion: version (or Promotion :: any)?   
 
  Simple answer? No. You can not convert through strings, it is a loss of information and  boost :: variant  does not attempt to parse the strings automatically.  
 I do not know  wxVariant  provides a clear conversion ??? In general, converting to  boost :: variant  without testing special cases can be difficult.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
