+/*
+ 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 descentants:
+
+ 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.
+
+ 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 actaul inter-
+ face for this is usually in wxScrolledWidget, 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 class would always contain
+ 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 widget. 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 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
+ 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.
