I have been asked several times about writing some documentation about

+ the GTK port of wxWidgets, especially its internal structures. Obviously,
you cannot understand wxGTK without knowing a little about the GTK, but
some more information about what the wxWindow, which is the base class
for all other window classes, does seems required as well.

+ Normally one might expect, that one wxWidgets window would always correspond
+ to one GTK widget. Under GTK, there is no such all-round widget that has all
the functionality. Moreover, the GTK defines a client area as a different
widget from the actual widget you are handling. Last but not least some
special classes (e.g. wxFrame) handle different categories of widgets and
still have the possibility to draw something in the client area.
It was therefore required to write a special purpose GTK widget, that would
- represent a client area in the sense of wxWindows capable to do the jobs

this directory.
All windows must have a widget, with which they interact with other under-
lying GTK widgets. It is this widget, e.g. that has to be resized etc and
- thw wxWindow class has a member variable called m_widget which holds a

pointer to this widget. When the window class represents a GTK native widget,
this is (in most cases) the only GTK widget the class manages. E.g. the
- wxStatitText class handles only a GtkLabel widget a pointer to which you

can find in m_widget (defined in wxWindow)
When the class has a client area for drawing into and for containing children

The common rule for all windows is only, that the widget that interacts with
the rest of GTK must be referenced in m_widget and all other widgets must be
children of this widget on the GTK level. The top-most widget, which also
represents the client area, must be in the m_wxwindow field and must be of
- the type GtkPizza.
+ the type wxPizza.
As I said, the window classes that display a GTK native widget only have
one widget, so in the case of e.g. the wxButton class m_widget holds a
pointer to a GtkButton widget. But windows with client areas (for drawing
and children) have a m_widget field that is a pointer to a GtkScrolled-
- Window and a m_wxwindow field that is pointer to a GtkPizza and this
+ Window and a m_wxwindow field that is pointer to a wxPizza and this
one is (in the GTK sense) a child of the GtkScrolledWindow.
If the m_wxwindow field is set, then all input to this widget is inter-
- cepted and sent to the wxWindows class. If not, all input to the widget

+ The design of scrolling in wxWidgets is markedly different from that offered
by the GTK itself and therefore we cannot simply take it as it is. In GTK,
clicking on a scrollbar belonging to scrolled window will inevitably move
- the window. In wxWindows, the scrollbar will only emit an event, send this
+ the window. In wxWidgets, the scrollbar will only emit an event, send this
to (normally) a wxScrolledWindow and that class will call ScrollWindow()
- which actually moves the window and its subchildren. Note that GtkPizza

so that the two coordinates systems have to be kept in synch. This is done
- in various places using the pizza->xoffset and pizza->yoffset values.
+ in various places using the pizza->m_scroll_x and pizza->m_scroll_y values.

- Singularily the most broken code in GTK is the code that is supposes to
+ Singularly the most broken code in GTK is the code that is supposed to
inform subwindows (child windows) about new positions. Very often, duplicate
events are sent without changes in size or position, equally often no
events are sent at all (All this is due to a bug in the GtkContainer code
which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
GTK's own system and it simply waits for size events for toplevel windows
and then iterates down the respective size events to all window. This has
- the disadvantage, that windows might get size events before the GTK widget
+ the disadvantage that windows might get size events before the GTK widget
actually has the reported size. This doesn't normally pose any problem, but
- the OpenGl drawing routines rely on correct behaviour. Therefore, I have
+ the OpenGL drawing routines rely on correct behaviour. Therefore, I have
added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,

If someone at some point of time feels the immense desire to have a look at,

+ intimate understanding of what "draw" and "expose" events are and what
+ they are used for, in particular when used in connection with GTK's
own windowless widgets. Beware.
V)
Cursors, too, have been a constant source of pleasure. The main difficulty
is that a GdkWindow inherits a cursor if the programmer sets a new cursor
- for the parent. To prevent this from doing too much harm, I use idle time
- to set the cursor over and over again, starting from the toplevel windows
- and ending with the youngest generation (speaking of parent and child windows).
+ for the parent. To prevent this from doing too much harm, SetCursor calls
+ GTKUpdateCursor, which will recursively re-set the cursors of all child windows.
Also don't forget that cursors (like much else) are connected to GdkWindows,
not GtkWidgets and that the "window" field of a GtkWidget might very well
- point to the GdkWindow of the parent widget (-> "window less widget") and
+ point to the GdkWindow of the parent widget (-> "window-less widget") and
that the two obviously have very different meanings.
