To get started with wxWindows, we will write a very simple
program that simply puts up a frame, a window with the typical decorations
that the windowing system provides.
The icons for minimizing or closing the window (etc.) vary
from system to system, but are not important to our discussion.
To use the wzWindows toolkit in your program, you need to
include the header file wx/w.h.
To the define a class that contains details about the workings
of your application.
class BasicApp: public wxApp
{
public:
BasicApp();
virtual bool OnInit(); /* override base class implementation */
private:
wxFrame* frame; /* this application has a frame */
};
