  40 /*
  41    I have been asked several times about writing some documentation about
  42    the GTK port of wxWindows, especially its internal structures. Obviously,
  43    you cannot understand wxGTK without knowing a little about the GTK, but
  44    some more information about what the wxWindow, which is the base class
  45    for all other window classes, does seems required as well.
  46
  47    What does wxWindow do? It contains the common interface for the following
  48    jobs of its descendants:
  49
  50    1) Define the rudimentary behaviour common to all window classes, such as
  51    resizing, intercepting user input (so as to make it possible to use these
  52    events for special purposes in a derived class), window names etc.
  53
  54    2) Provide the possibility to contain and manage children, if the derived
  55    class is allowed to contain children, which holds true for those window
  56    classes which do not display a native GTK widget. To name them, these
  57    classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
  58    work classes are a special case and are handled a bit differently from
  59    the rest. The same holds true for the wxNotebook class.
  60
  61    3) Provide the possibility to draw into a client area of a window. This,
  62    too, only holds true for classes that do not display a native GTK widget
  63    as above.
  64
  65    4) Provide the entire mechanism for scrolling widgets. This actual inter-
  66    face for this is usually in wxScrolledWindow, but the GTK implementation
  67    is in this class.
  68
  69    5) A multitude of helper or extra methods for special purposes, such as
  70    Drag'n'Drop, managing validators etc.
  71
  72    Normally one might expect, that one wxWindows window would always correspond
  73    to one GTK widget. Under GTK, there is no such allround widget that has all
  74    the functionality. Moreover, the GTK defines a client area as a different
  75    widget from the actual widget you are handling. Last but not least some
  76    special classes (e.g. wxFrame) handle different categories of widgets and
  77    still have the possibility to draw something in the client area.
  78    It was therefore required to write a special purpose GTK widget, that would
  79    represent a client area in the sense of wxWindows capable to do the jobs
  80    2), 3) and 4). I have written this class and it resides in win_gtk.c of
  81    this directory.
  82
  83    All windows must have a widget, with which they interact with other under-
  84    lying GTK widgets. It is this widget, e.g. that has to be resized etc and
  85    thw wxWindow class has a member variable called m_widget which holds a
  86    pointer to this widget. When the window class represents a GTK native widget,
  87    this is (in most cases) the only GTK widget the class manages. E.g. the
  88    wxStatitText class handles only a GtkLabel widget a pointer to which you
  89    can find in m_widget (defined in wxWindow)
  90
  91    When the class has a client area for drawing into and for containing children
  92    it has to handle the client area widget (of the type GtkMyFixed, defined in
  93    win_gtk.c), but there could be any number of widgets, handled by a class
  94    The common rule for all windows is only, that the widget that interacts with
  95    the rest of GTK must be referenced in m_widget and all other widgets must be
  96    children of this widget on the GTK level. The top-most widget, which also
  97    represents the client area, must be in the m_wxwindow field and must be of
  98    the type GtkMyFixed.
  99
 100    As I said, the window classes that display a GTK native widget only have
 101    one widget, so in the case of e.g. the wxButton class m_widget holds a
 102    pointer to a GtkButton widget. But windows with client areas (for drawing
 103    and children) have a m_widget field that is a pointer to a GtkScrolled-
 104    Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
 105    one is (in the GTK sense) a child of the GtkScrolledWindow.
 106
 107    If the m_wxwindow field is set, then all input to this widget is inter-
 108    cepted and sent to the wxWindows class. If not, all input to the widget
 109    that gets pointed to by m_widget gets intercepted and sent to the class.
