Detailed Description

The Root IG Application object.

  To run the IG simply create one, initialize it and call run. 
  @code 

#include <vrvCore/DtVrvApplication.h>

using namespace makVrv;

int main(int argc,char** argv) { DtVrvApplication igApp; igApp.initialize(argc, argv); igApp.run(); }

virtual void makVrv::DtVrvApplication::initialize ( int  argc, char **  argv  )

virtual

Create the GUI, initialize the DtDe.

Call before calling run().

1. Sets the DtVrvConfiguration.
2. Assembles the user interface.
