2) Provide the possibility to contain and manage children, if the derived
class is allowed to contain children, which holds true for those window
- classes, which do not display a native GTK widget. To name them, these

+ Normally one might expect, that one wxWindows window would always correspond
+ to one GTK widget. Under GTK, there is no such allround widget that has all
the functionality. Moreover, the GTK defines a client area as a different
widget from the actual widget you are handling. Last but not least some
special classes (e.g. wxFrame) handle different categories of widgets and

All windows must have a widget, with which they interact with other under-

thw wxWindow class has a member variable called m_widget which holds a
- pointer to this widget. When the window class displays a GTK native widget,
- this is the only GTK widget the class manages. When the class has a client
- area for drawing into and for containing children it must have at least
- one more GTK widget to handle (of the type GtkMyFixed, defined in win_gtk.c),
- but there can be any number of widgets, handled by a class (e.g. the frame
- class handles three). The common rule for all windows is only, that the
- widget that interacts with the rest of GTK must be referenced in m_widget
