Function documentation

TGApplication(const char* appClassName, Int_t* argc, char** argv, void* options = 0, Int_t numOptions = 0)

 Create a GUI application environment. Use this class if you only
 want to use the ROOT GUI and no other services. In all other cases
 use either TApplication or TRint.

~TGApplication()

 TGApplication dtor.

void LoadGraphicsLibs()

 Load shared libs necessary for GUI.

void GetOptions(Int_t* argc, char** argv)

 Handle command line arguments. Arguments handled are removed from the
 argument array. Currently only option "-display xserver" is considered.
