/*
   I have been asked several times about writing some documentation about
   the GTK port of wxWindows, especially its internal structures. Obviously,
   you cannot understand wxGTK without knowing a little about the GTK, but
   some more information about what the wxWindow, which is the base class
   for all other window classes, does seems required as well.

   What does wxWindow do? It contains the common interface for the following
   jobs of its descendants:

   1) Define the rudimentary behaviour common to all window classes, such as
   resizing, intercepting user input (so as to make it possible to use these
   events for special purposes in a derived class), window names etc.

   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
   classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
   work classes are a special case and are handled a bit differently from
   the rest. The same holds true for the wxNotebook class.

   3) Provide the possibility to draw into a client area of a window. This,
   too, only holds true for classes that do not display a native GTK widget
   as above.

   4) Provide the entire mechanism for scrolling widgets. This actual inter-
   face for this is usually in wxScrolledWindow, but the GTK implementation
   is in this class.

   5) A multitude of helper or extra methods for special purposes, such as
   Drag'n'Drop, managing validators etc.

   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
   still have the possibility to draw something in the client area.
   It was therefore required to write a special purpose GTK widget, that would
   represent a client area in the sense of wxWindows capable to do the jobs
   2), 3) and 4). I have written this class and it resides in win_gtk.c of
   this directory.

   All windows must have a widget, with which they interact with other under-
   lying GTK widgets. It is this widget, e.g. that has to be resized etc and
   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
   can find in m_widget (defined in wxWindow)

   When the class has a client area for drawing into and for containing children
   it has to handle the client area widget (of the type GtkMyFixed, defined in
   win_gtk.c), but there could be any number of widgets, handled by a class
   The common rule for all windows is only, that the widget that interacts with
   the rest of GTK must be referenced in m_widget and all other widgets must be
   children of this widget on the GTK level. The top-most widget, which also
   represents the client area, must be in the m_wxwindow field and must be of
   the type GtkMyFixed.

   As I said, the window classes that display a GTK native widget only have
   one widget, so in the case of e.g. the wxButton class m_widget holds a
   pointer to a GtkButton widget. But windows with client areas (for drawing
   and children) have a m_widget field that is a pointer to a GtkScrolled-
   Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
   one is (in the GTK sense) a child of the GtkScrolledWindow.

   If the m_wxwindow field is set, then all input to this widget is inter-
   cepted and sent to the wxWindows class. If not, all input to the widget
   that gets pointed to by m_widget gets intercepted and sent to the class.

	   which is its client area. therefore, we have to tell the
	   client area directly that it has to resize itself.
	   this will lead to that m_widget (GtkScrolledWindow) will
	   calculate how much size it needs for scrollbars etc and
	   it will then call XXX_size_allocate of its child, which
	   is m_wxwindow. m_wxwindow in turn will do the same with its
	   children and so on. problems can arise if this happens
	   before all the children have been realized as some widgets
	   stupidy need to be realized during XXX_size_allocate (e.g.
	   GtkNotebook) and they will segv if called otherwise. this
	   emergency is tested in gtk_myfixed_size_allocate. Normally
	   this shouldn't be needed and only gtk_widget_queue_resize()
	   should be enough to provoke a resize at the next appropriate
	   moment, but this seems to fail, e.g. when a wxNotebook contains
