  88 /*
  89    I have been asked several times about writing some documentation about
  90    the GTK port of wxWindows, especially its internal structures. Obviously,
  91    you cannot understand wxGTK without knowing a little about the GTK, but
  92    some more information about what the wxWindow, which is the base class
  93    for all other window classes, does seems required as well.
  94
  95    I)
  96
  97    What does wxWindow do? It contains the common interface for the following
  98    jobs of its descendants:
  99
 100    1) Define the rudimentary behaviour common to all window classes, such as
 101    resizing, intercepting user input (so as to make it possible to use these
 102    events for special purposes in a derived class), window names etc.
 103
 104    2) Provide the possibility to contain and manage children, if the derived
 105    class is allowed to contain children, which holds true for those window
 106    classes which do not display a native GTK widget. To name them, these
 107    classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
 108    work classes are a special case and are handled a bit differently from
 109    the rest. The same holds true for the wxNotebook class.
 110
 111    3) Provide the possibility to draw into a client area of a window. This,
 112    too, only holds true for classes that do not display a native GTK widget
 113    as above.
 114
 115    4) Provide the entire mechanism for scrolling widgets. This actual inter-
 116    face for this is usually in wxScrolledWindow, but the GTK implementation
 117    is in this class.
 118
 119    5) A multitude of helper or extra methods for special purposes, such as
 120    Drag'n'Drop, managing validators etc.
 121
 122    6) Display a border (sunken, raised, simple or none).
 123
 124    Normally one might expect, that one wxWindows window would always correspond
 125    to one GTK widget. Under GTK, there is no such allround widget that has all
 126    the functionality. Moreover, the GTK defines a client area as a different
 127    widget from the actual widget you are handling. Last but not least some
 128    special classes (e.g. wxFrame) handle different categories of widgets and
 129    still have the possibility to draw something in the client area.
 130    It was therefore required to write a special purpose GTK widget, that would
 131    represent a client area in the sense of wxWindows capable to do the jobs
 132    2), 3) and 4). I have written this class and it resides in win_gtk.c of
 133    this directory.
 134
 135    All windows must have a widget, with which they interact with other under-
 136    lying GTK widgets. It is this widget, e.g. that has to be resized etc and
 137    thw wxWindow class has a member variable called m_widget which holds a
 138    pointer to this widget. When the window class represents a GTK native widget,
 139    this is (in most cases) the only GTK widget the class manages. E.g. the
 140    wxStatitText class handles only a GtkLabel widget a pointer to which you
 141    can find in m_widget (defined in wxWindow)
 142
 143    When the class has a client area for drawing into and for containing children
 144    it has to handle the client area widget (of the type GtkPizza, defined in
 145    win_gtk.c), but there could be any number of widgets, handled by a class
 146    The common rule for all windows is only, that the widget that interacts with
 147    the rest of GTK must be referenced in m_widget and all other widgets must be
 148    children of this widget on the GTK level. The top-most widget, which also
 149    represents the client area, must be in the m_wxwindow field and must be of
 150    the type GtkPizza.
 151
 152    As I said, the window classes that display a GTK native widget only have
 153    one widget, so in the case of e.g. the wxButton class m_widget holds a
 154    pointer to a GtkButton widget. But windows with client areas (for drawing
 155    and children) have a m_widget field that is a pointer to a GtkScrolled-
 156    Window and a m_wxwindow field that is pointer to a GtkPizza and this
 157    one is (in the GTK sense) a child of the GtkScrolledWindow.
 158
 159    If the m_wxwindow field is set, then all input to this widget is inter-
 160    cepted and sent to the wxWindows class. If not, all input to the widget
 161    that gets pointed to by m_widget gets intercepted and sent to the class.
 162
 163    II)
 164
 165    The design of scrolling in wxWindows is markedly different from that offered
 166    by the GTK itself and therefore we cannot simply take it as it is. In GTK,
 167    clicking on a scrollbar belonging to scrolled window will inevitably move
 168    the window. In wxWindows, the scrollbar will only emit an event, send this
 169    to (normally) a wxScrolledWindow and that class will call ScrollWindow()
 170    which actually moves the window and its subchildren. Note that GtkPizza
 171    memorizes how much it has been scrolled but that wxWindows forgets this
 172    so that the two coordinates systems have to be kept in synch. This is done
 173    in various places using the pizza->xoffset and pizza->yoffset values.
 174
 175    III)
 176
 177    Singularily the most broken code in GTK is the code that is supposes to
 178    inform subwindows (child windows) about new positions. Very often, duplicate
 179    events are sent without changes in size or position, equally often no
 180    events are sent at all (All this is due to a bug in the GtkContainer code
 181    which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
 182    GTK's own system and it simply waits for size events for toplevel windows
 183    and then iterates down the respective size events to all window. This has
 184    the disadvantage, that windows might get size events before the GTK widget
 185    actually has the reported size. This doesn't normally pose any problem, but
 186    the OpenGl drawing routines rely on correct behaviour. Therefore, I have
 187    added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
 188    i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
 189    window that is used for OpenGl output really has that size (as reported by
 190    GTK).
 191
 192    IV)
 193
 194    If someone at some point of time feels the immense desire to have a look at,
 195    change or attempt to optimse the Refresh() logic, this person will need an
 196    intimate understanding of what a "draw" and what an "expose" events are and
 197    what there are used for, in particular when used in connection with GTK's
 198    own windowless widgets. Beware.
 199
 200    V)
 201
 202    Cursors, too, have been a constant source of pleasure. The main difficulty
 203    is that a GdkWindow inherits a cursor if the programmer sets a new cursor
 204    for the parent. To prevent this from doing too much harm, I use idle time
 205    to set the cursor over and over again, starting from the toplevel windows
 206    and ending with the youngest generation (speaking of parent and child windows).
 207    Also don't forget that cursors (like much else) are connected to GdkWindows,
 208    not GtkWidgets and that the "window" field of a GtkWidget might very well
 209    point to the GdkWindow of the parent widget (-> "window less widget") and
 210    that the two obviously have very different meanings.
