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