  45 /*
  46    I have been asked several times about writing some documentation about
  47    the GTK port of wxWindows, especially its internal structures. Obviously,
  48    you cannot understand wxGTK without knowing a little about the GTK, but
  49    some more information about what the wxWindow, which is the base class
  50    for all other window classes, does seems required as well.
  51
  52    What does wxWindow do? It contains the common interface for the following
  53    jobs of its descendants:
  54
  55    1) Define the rudimentary behaviour common to all window classes, such as
  56    resizing, intercepting user input (so as to make it possible to use these
  57    events for special purposes in a derived class), window names etc.
  58
  59    2) Provide the possibility to contain and manage children, if the derived
  60    class is allowed to contain children, which holds true for those window
  61    classes which do not display a native GTK widget. To name them, these
  62    classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
  63    work classes are a special case and are handled a bit differently from
  64    the rest. The same holds true for the wxNotebook class.
  65
  66    3) Provide the possibility to draw into a client area of a window. This,
  67    too, only holds true for classes that do not display a native GTK widget
  68    as above.
  69
  70    4) Provide the entire mechanism for scrolling widgets. This actual inter-
  71    face for this is usually in wxScrolledWindow, but the GTK implementation
  72    is in this class.
  73
  74    5) A multitude of helper or extra methods for special purposes, such as
  75    Drag'n'Drop, managing validators etc.
  76
  77    Normally one might expect, that one wxWindows window would always correspond
  78    to one GTK widget. Under GTK, there is no such allround widget that has all
  79    the functionality. Moreover, the GTK defines a client area as a different
  80    widget from the actual widget you are handling. Last but not least some
  81    special classes (e.g. wxFrame) handle different categories of widgets and
  82    still have the possibility to draw something in the client area.
  83    It was therefore required to write a special purpose GTK widget, that would
  84    represent a client area in the sense of wxWindows capable to do the jobs
  85    2), 3) and 4). I have written this class and it resides in win_gtk.c of
  86    this directory.
  87
  88    All windows must have a widget, with which they interact with other under-
  89    lying GTK widgets. It is this widget, e.g. that has to be resized etc and
  90    thw wxWindow class has a member variable called m_widget which holds a
  91    pointer to this widget. When the window class represents a GTK native widget,
  92    this is (in most cases) the only GTK widget the class manages. E.g. the
  93    wxStatitText class handles only a GtkLabel widget a pointer to which you
  94    can find in m_widget (defined in wxWindow)
  95
  96    When the class has a client area for drawing into and for containing children
  97    it has to handle the client area widget (of the type GtkMyFixed, defined in
  98    win_gtk.c), but there could be any number of widgets, handled by a class
  99    The common rule for all windows is only, that the widget that interacts with
 100    the rest of GTK must be referenced in m_widget and all other widgets must be
 101    children of this widget on the GTK level. The top-most widget, which also
 102    represents the client area, must be in the m_wxwindow field and must be of
 103    the type GtkMyFixed.
 104
 105    As I said, the window classes that display a GTK native widget only have
 106    one widget, so in the case of e.g. the wxButton class m_widget holds a
 107    pointer to a GtkButton widget. But windows with client areas (for drawing
 108    and children) have a m_widget field that is a pointer to a GtkScrolled-
 109    Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
 110    one is (in the GTK sense) a child of the GtkScrolledWindow.
 111
 112    If the m_wxwindow field is set, then all input to this widget is inter-
 113    cepted and sent to the wxWindows class. If not, all input to the widget
 114    that gets pointed to by m_widget gets intercepted and sent to the class.
