  72 /*
  73    I have been asked several times about writing some documentation about
  74    the GTK port of wxWidgets, especially its internal structures. Obviously,
  75    you cannot understand wxGTK without knowing a little about the GTK, but
  76    some more information about what the wxWindow, which is the base class
  77    for all other window classes, does seems required as well.
  78
  79    I)
  80
  81    What does wxWindow do? It contains the common interface for the following
  82    jobs of its descendants:
  83
  84    1) Define the rudimentary behaviour common to all window classes, such as
  85    resizing, intercepting user input (so as to make it possible to use these
  86    events for special purposes in a derived class), window names etc.
  87
  88    2) Provide the possibility to contain and manage children, if the derived
  89    class is allowed to contain children, which holds true for those window
  90    classes which do not display a native GTK widget. To name them, these
  91    classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
  92    work classes are a special case and are handled a bit differently from
  93    the rest. The same holds true for the wxNotebook class.
  94
  95    3) Provide the possibility to draw into a client area of a window. This,
  96    too, only holds true for classes that do not display a native GTK widget
  97    as above.
  98
  99    4) Provide the entire mechanism for scrolling widgets. This actual inter-
 100    face for this is usually in wxScrolledWindow, but the GTK implementation
 101    is in this class.
 102
 103    5) A multitude of helper or extra methods for special purposes, such as
 104    Drag'n'Drop, managing validators etc.
 105
 106    6) Display a border (sunken, raised, simple or none).
 107
 108    Normally one might expect, that one wxWidgets window would always correspond
 109    to one GTK widget. Under GTK, there is no such allround widget that has all
 110    the functionality. Moreover, the GTK defines a client area as a different
 111    widget from the actual widget you are handling. Last but not least some
 112    special classes (e.g. wxFrame) handle different categories of widgets and
 113    still have the possibility to draw something in the client area.
 114    It was therefore required to write a special purpose GTK widget, that would
 115    represent a client area in the sense of wxWidgets capable to do the jobs
 116    2), 3) and 4). I have written this class and it resides in win_gtk.c of
 117    this directory.
 118
 119    All windows must have a widget, with which they interact with other under-
 120    lying GTK widgets. It is this widget, e.g. that has to be resized etc and
 121    the wxWindow class has a member variable called m_widget which holds a
 122    pointer to this widget. When the window class represents a GTK native widget,
 123    this is (in most cases) the only GTK widget the class manages. E.g. the
 124    wxStaticText class handles only a GtkLabel widget a pointer to which you
 125    can find in m_widget (defined in wxWindow)
 126
 127    When the class has a client area for drawing into and for containing children
 128    it has to handle the client area widget (of the type GtkPizza, defined in
 129    win_gtk.c), but there could be any number of widgets, handled by a class
 130    The common rule for all windows is only, that the widget that interacts with
 131    the rest of GTK must be referenced in m_widget and all other widgets must be
 132    children of this widget on the GTK level. The top-most widget, which also
 133    represents the client area, must be in the m_wxwindow field and must be of
 134    the type GtkPizza.
 135
 136    As I said, the window classes that display a GTK native widget only have
 137    one widget, so in the case of e.g. the wxButton class m_widget holds a
 138    pointer to a GtkButton widget. But windows with client areas (for drawing
 139    and children) have a m_widget field that is a pointer to a GtkScrolled-
 140    Window and a m_wxwindow field that is pointer to a GtkPizza and this
 141    one is (in the GTK sense) a child of the GtkScrolledWindow.
 142
 143    If the m_wxwindow field is set, then all input to this widget is inter-
 144    cepted and sent to the wxWidgets class. If not, all input to the widget
 145    that gets pointed to by m_widget gets intercepted and sent to the class.
 146
 147    II)
 148
 149    The design of scrolling in wxWidgets is markedly different from that offered
 150    by the GTK itself and therefore we cannot simply take it as it is. In GTK,
 151    clicking on a scrollbar belonging to scrolled window will inevitably move
 152    the window. In wxWidgets, the scrollbar will only emit an event, send this
 153    to (normally) a wxScrolledWindow and that class will call ScrollWindow()
 154    which actually moves the window and its subchildren. Note that GtkPizza
 155    memorizes how much it has been scrolled but that wxWidgets forgets this
 156    so that the two coordinates systems have to be kept in synch. This is done
 157    in various places using the pizza->xoffset and pizza->yoffset values.
 158
 159    III)
 160
 161    Singularily the most broken code in GTK is the code that is supposed to
 162    inform subwindows (child windows) about new positions. Very often, duplicate
 163    events are sent without changes in size or position, equally often no
 164    events are sent at all (All this is due to a bug in the GtkContainer code
 165    which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
 166    GTK's own system and it simply waits for size events for toplevel windows
 167    and then iterates down the respective size events to all window. This has
 168    the disadvantage that windows might get size events before the GTK widget
 169    actually has the reported size. This doesn't normally pose any problem, but
 170    the OpenGL drawing routines rely on correct behaviour. Therefore, I have
 171    added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
 172    i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
 173    window that is used for OpenGL output really has that size (as reported by
 174    GTK).
 175
 176    IV)
 177
 178    If someone at some point of time feels the immense desire to have a look at,
 179    change or attempt to optimise the Refresh() logic, this person will need an
 180    intimate understanding of what "draw" and "expose" events are and what
 181    they are used for, in particular when used in connection with GTK's
 182    own windowless widgets. Beware.
 183
 184    V)
 185
 186    Cursors, too, have been a constant source of pleasure. The main difficulty
 187    is that a GdkWindow inherits a cursor if the programmer sets a new cursor
 188    for the parent. To prevent this from doing too much harm, I use idle time
 189    to set the cursor over and over again, starting from the toplevel windows
 190    and ending with the youngest generation (speaking of parent and child windows).
 191    Also don't forget that cursors (like much else) are connected to GdkWindows,
 192    not GtkWidgets and that the "window" field of a GtkWidget might very well
 193    point to the GdkWindow of the parent widget (-> "window-less widget") and
 194    that the two obviously have very different meanings.
