Was willst du genau wissen?
Wie der Konstruktor aussieht, steht in der Doku: http://docs.wxwidgets.org/stable/wx_classref.html#classref
Ansonsten einfach:
class myctrl : public wxChoice
{
public:
myctrl(wxWindow *parent, wxWindowID id, const wxPoint& pos, const wxSize& size, int n, const wxString choices[], long style = 0,
const wxValidator& validator = wxDefaultValidator, const wxString& name = "myctrl")
: public wxChoice(parent, id, pos, size, n, choices, style, validator, name)
}
