thw wxWindow class has a member variable called m_widget which holds a
pointer to this widget. When the window class represents a GTK native widget,
this is (in most cases) the only GTK widget the class manages. E.g. the
- wxStatitText class handles only a GtkLabel widget a pointer to which you
+ wxStaticText class handles only a GtkLabel widget a pointer to which you
can find in m_widget (defined in wxWindow)
When the class has a client area for drawing into and for containing children
