56 // documentation on internals
57 //-----------------------------------------------------------------------------
60 I have been asked several times about writing some documentation about
61 the GTK port of wxWidgets, especially its internal structures. Obviously,
62 you cannot understand wxGTK without knowing a little about the GTK, but
63 some more information about what the wxWindow, which is the base class
64 for all other window classes, does seems required as well.
68 What does wxWindow do? It contains the common interface for the following
69 jobs of its descendants:
71 1) Define the rudimentary behaviour common to all window classes, such as
72 resizing, intercepting user input (so as to make it possible to use these
73 events for special purposes in a derived class), window names etc.
75 2) Provide the possibility to contain and manage children, if the derived
76 class is allowed to contain children, which holds true for those window
77 classes which do not display a native GTK widget. To name them, these
78 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
79 work classes are a special case and are handled a bit differently from
80 the rest. The same holds true for the wxNotebook class.
82 3) Provide the possibility to draw into a client area of a window. This,
83 too, only holds true for classes that do not display a native GTK widget
86 4) Provide the entire mechanism for scrolling widgets. This actual inter-
87 face for this is usually in wxScrolledWindow, but the GTK implementation
90 5) A multitude of helper or extra methods for special purposes, such as
91 Drag'n'Drop, managing validators etc.
93 6) Display a border (sunken, raised, simple or none).
95 Normally one might expect, that one wxWidgets window would always correspond
96 to one GTK widget. Under GTK, there is no such all-round widget that has all
97 the functionality. Moreover, the GTK defines a client area as a different
98 widget from the actual widget you are handling. Last but not least some
99 special classes (e.g. wxFrame) handle different categories of widgets and
100 still have the possibility to draw something in the client area.
101 It was therefore required to write a special purpose GTK widget, that would
102 represent a client area in the sense of wxWidgets capable to do the jobs
103 2), 3) and 4). I have written this class and it resides in win_gtk.c of
106 All windows must have a widget, with which they interact with other under-
107 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
108 the wxWindow class has a member variable called m_widget which holds a
109 pointer to this widget. When the window class represents a GTK native widget,
110 this is (in most cases) the only GTK widget the class manages. E.g. the
111 wxStaticText class handles only a GtkLabel widget a pointer to which you
112 can find in m_widget (defined in wxWindow)
114 When the class has a client area for drawing into and for containing children
115 it has to handle the client area widget (of the type GtkPizza, defined in
116 win_gtk.c), but there could be any number of widgets, handled by a class
117 The common rule for all windows is only, that the widget that interacts with
118 the rest of GTK must be referenced in m_widget and all other widgets must be
119 children of this widget on the GTK level. The top-most widget, which also
120 represents the client area, must be in the m_wxwindow field and must be of
123 As I said, the window classes that display a GTK native widget only have
124 one widget, so in the case of e.g. the wxButton class m_widget holds a
125 pointer to a GtkButton widget. But windows with client areas (for drawing
126 and children) have a m_widget field that is a pointer to a GtkScrolled-
127 Window and a m_wxwindow field that is pointer to a GtkPizza and this
128 one is (in the GTK sense) a child of the GtkScrolledWindow.
130 If the m_wxwindow field is set, then all input to this widget is inter-
131 cepted and sent to the wxWidgets class. If not, all input to the widget
132 that gets pointed to by m_widget gets intercepted and sent to the class.
136 The design of scrolling in wxWidgets is markedly different from that offered
137 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
138 clicking on a scrollbar belonging to scrolled window will inevitably move
139 the window. In wxWidgets, the scrollbar will only emit an event, send this
140 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
141 which actually moves the window and its sub-windows. Note that GtkPizza
142 memorizes how much it has been scrolled but that wxWidgets forgets this
143 so that the two coordinates systems have to be kept in synch. This is done
144 in various places using the pizza->xoffset and pizza->yoffset values.
148 Singularly the most broken code in GTK is the code that is supposed to
149 inform subwindows (child windows) about new positions. Very often, duplicate
150 events are sent without changes in size or position, equally often no
151 events are sent at all (All this is due to a bug in the GtkContainer code
152 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
153 GTK's own system and it simply waits for size events for toplevel windows
154 and then iterates down the respective size events to all window. This has
155 the disadvantage that windows might get size events before the GTK widget
156 actually has the reported size. This doesn't normally pose any problem, but
157 the OpenGL drawing routines rely on correct behaviour. Therefore, I have
158 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
159 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
160 window that is used for OpenGL output really has that size (as reported by
165 If someone at some point of time feels the immense desire to have a look at,
166 change or attempt to optimise the Refresh() logic, this person will need an
167 intimate understanding of what "draw" and "expose" events are and what
168 they are used for, in particular when used in connection with GTK's
169 own windowless widgets. Beware.
173 Cursors, too, have been a constant source of pleasure. The main difficulty
174 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
175 for the parent. To prevent this from doing too much harm, I use idle time
176 to set the cursor over and over again, starting from the toplevel windows
177 and ending with the youngest generation (speaking of parent and child windows).
178 Also don't forget that cursors (like much else) are connected to GdkWindows,
179 not GtkWidgets and that the "window" field of a GtkWidget might very well
180 point to the GdkWindow of the parent widget (-> "window-less widget") and
181 that the two obviously have very different meanings.
