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