+/*
+   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.
+
+   I)
+
+   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.
+
+   6) Display a border (sunken, raised, simple or none).
+
+   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 GtkPizza, 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 GtkPizza.
+
+   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 GtkPizza 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.
+
+   II)
+
+   The design of scrolling in wxWindows is markedly different from that offered
+   by the GTK itself and therefore we cannot simply take it as it is. In GTK,
+   clicking on a scrollbar belonging to scrolled window will inevitably move
+   the window. In wxWindows, the scrollbar will only emit an event, send this
+   to (normally) a wxScrolledWindow and that class will call ScrollWindow()
+   which actually moves the window and its subchildren. Note that GtkPizza
+   memorizes how much it has been scrolled but that wxWindows forgets this
+   so that the two coordinates systems have to be kept in synch. This is done
+   in various places using the pizza->xoffset and pizza->yoffset values.
+
+   III)
+
+   Singularily the most broken code in GTK is the code that is supposes to
+   inform subwindows (child windows) about new positions. Very often, duplicate
+   events are sent without changes in size or position, equally often no
+   events are sent at all (All this is due to a bug in the GtkContainer code
+   which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
+   GTK's own system and it simply waits for size events for toplevel windows
+   and then iterates down the respective size events to all window. This has
+   the disadvantage, that windows might get size events before the GTK widget
+   actually has the reported size. This doesn't normally pose any problem, but
+   the OpenGl drawing routines rely on correct behaviour. Therefore, I have
+   added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
+   i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
+   window that is used for OpenGl output really has that size (as reported by
+   GTK).
+
+   IV)
+
+   If someone at some point of time feels the immense desire to have a look at,
+   change or attempt to optimse the Refresh() logic, this person will need an
+   intimate understanding of what a "draw" and what an "expose" events are and
+   what there are used for, in particular when used in connection with GTK's
+   own windowless widgets. Beware.
+
+   V)
+
+   Cursors, too, have been a constant source of pleasure. The main difficulty
+   is that a GdkWindow inherits a cursor if the programmer sets a new cursor
+   for the parent. To prevent this from doing too much harm, I use idle time
+   to set the cursor over and over again, starting from the toplevel windows
+   and ending with the youngest generation (speaking of parent and child windows).
+   Also don't forget that cursors (like much else) are connected to GdkWindows,
+   not GtkWidgets and that the "window" field of a GtkWidget might very well
+   point to the GdkWindow of the parent widget (-> "window less widget") and
+   that the two obviously have very different meanings.
