wxwidgets: initialize wxapp but controlling macros but entering sure concentration loop?

we need section tests wxwidgets concentration controlling google exam framework.
the problem wxwidgets uses macro implement_app(myapp) initialize enter concentration sure loop. macro creates several functions including int main(). google exam horizon also uses macro definitions any test.

one problems illusory wxwidgets macro within exam macro, since initial creates functions.. so, found reinstate macro following code:

wxapp* papp = new myapp(); 
wxapp::setinstance(papp);
wxentry(argc, argv);

that's good replacement, nonetheless wxentry() enters uncanny concentration loop. don't wxentry() there still tools concentration initialized.

the doubt initialize all mandatory wxapp run, but indeed controlling it, means section exam portions it?
