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