Good day.
I am trying to separate my main C++ model from the wxUI but have them be able to communicate with each other, above are the codes( the wxWidgets part is generated automatically). When I run the project it displays the window as wanted but the window disappears after few seconds.

I need help to achieve this and don't know where I go wrong.
