/*
I have been asked several times about writing some documentation about
- the GTK port of wxWindows, especially its internal structures. Obviously,
+ 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.
+ I)
+
What does wxWindow do? It contains the common interface for the following
jobs of its descendants:
5) A multitude of helper or extra methods for special purposes, such as
Drag'n'Drop, managing validators etc.
- Normally one might expect, that one wxWindows window would always correspond
+ 6) Display a border (sunken, raised, simple or none).
+
+ Normally one might expect, that one wxWidgets window would always correspond
to one GTK widget. Under GTK, there is no such allround 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
+ represent a client area in the sense of wxWidgets capable to do the jobs
2), 3) and 4). I have written this class and it resides in win_gtk.c of
this directory.
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
+ wxStaticText 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
- it has to handle the client area widget (of the type GtkMyFixed, defined in
+ it has to handle the client area widget (of the type GtkPizza, defined in
win_gtk.c), but there could be any number of widgets, handled by a class
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 GtkMyFixed.
+ the type GtkPizza.
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 GtkMyFixed and this
+ Window and a m_wxwindow field that is pointer to a GtkPizza 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
+ cepted and sent to the wxWidgets class. If not, all input to the widget
that gets pointed to by m_widget gets intercepted and sent to the class.
+ II)
+
+ 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 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
+ memorizes how much it has been scrolled but that wxWidgets forgets this
+ 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.
+
+ III)
+
+ Singularily the most broken code in GTK is the code that is supposes 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
+ actually has the reported size. This doesn't normally pose any problem, but
+ the OpenGl drawing routines rely on correct behaviour. Therefore, I have
+ added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
+ i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
+ window that is used for OpenGl output really has that size (as reported by
+ GTK).
+
+ IV)
+
+ If someone at some point of time feels the immense desire to have a look at,
+ change or attempt to optimse the Refresh() logic, this person will need an
+ intimate understanding of what a "draw" and what an "expose" events are and
+ what there 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).
+ 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
+ that the two obviously have very different meanings.

- this will lead to that m_widget (GtkScrolledWindow) will
- calculate how much size it needs for scrollbars etc and
- it will then call XXX_size_allocate of its child, which
- is m_wxwindow. m_wxwindow in turn will do the same with its
- children and so on. problems can arise if this happens
- before all the children have been realized as some widgets
- stupidy need to be realized during XXX_size_allocate (e.g.
- GtkNotebook) and they will segv if called otherwise. this
- emergency is tested in gtk_myfixed_size_allocate. Normally
- this shouldn't be needed and only gtk_widget_queue_resize()
- should be enough to provoke a resize at the next appropriate
