91/*
92 I have been asked several times about writing some documentation about
93 the GTK port of wxWidgets, especially its internal structures. Obviously,
94 you cannot understand wxGTK without knowing a little about the GTK, but
95 some more information about what the wxWindow, which is the base class
96 for all other window classes, does seems required as well.
97
98 I)
99
100 What does wxWindow do? It contains the common interface for the following
101 jobs of its descendants:
102
103 1) Define the rudimentary behaviour common to all window classes, such as
104 resizing, intercepting user input (so as to make it possible to use these
105 events for special purposes in a derived class), window names etc.
106
107 2) Provide the possibility to contain and manage children, if the derived
108 class is allowed to contain children, which holds true for those window
109 classes which do not display a native GTK widget. To name them, these
110 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
111 work classes are a special case and are handled a bit differently from
112 the rest. The same holds true for the wxNotebook class.
113
114 3) Provide the possibility to draw into a client area of a window. This,
115 too, only holds true for classes that do not display a native GTK widget
116 as above.
117
118 4) Provide the entire mechanism for scrolling widgets. This actual inter-
119 face for this is usually in wxScrolledWindow, but the GTK implementation
120 is in this class.
121
122 5) A multitude of helper or extra methods for special purposes, such as
123 Drag'n'Drop, managing validators etc.
124
125 6) Display a border (sunken, raised, simple or none).
126
127 Normally one might expect, that one wxWidgets window would always correspond
128 to one GTK widget. Under GTK, there is no such allround widget that has all
129 the functionality. Moreover, the GTK defines a client area as a different
130 widget from the actual widget you are handling. Last but not least some
131 special classes (e.g. wxFrame) handle different categories of widgets and
132 still have the possibility to draw something in the client area.
133 It was therefore required to write a special purpose GTK widget, that would
134 represent a client area in the sense of wxWidgets capable to do the jobs
135 2), 3) and 4). I have written this class and it resides in win_gtk.c of
136 this directory.
137
138 All windows must have a widget, with which they interact with other under-
139 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
140 thw wxWindow class has a member variable called m_widget which holds a
141 pointer to this widget. When the window class represents a GTK native widget,
142 this is (in most cases) the only GTK widget the class manages. E.g. the
143 wxStaticText class handles only a GtkLabel widget a pointer to which you
144 can find in m_widget (defined in wxWindow)
145
146 When the class has a client area for drawing into and for containing children
147 it has to handle the client area widget (of the type GtkPizza, defined in
148 win_gtk.c), but there could be any number of widgets, handled by a class
149 The common rule for all windows is only, that the widget that interacts with
150 the rest of GTK must be referenced in m_widget and all other widgets must be
151 children of this widget on the GTK level. The top-most widget, which also
152 represents the client area, must be in the m_wxwindow field and must be of
153 the type GtkPizza.
154
155 As I said, the window classes that display a GTK native widget only have
156 one widget, so in the case of e.g. the wxButton class m_widget holds a
157 pointer to a GtkButton widget. But windows with client areas (for drawing
158 and children) have a m_widget field that is a pointer to a GtkScrolled-
159 Window and a m_wxwindow field that is pointer to a GtkPizza and this
160 one is (in the GTK sense) a child of the GtkScrolledWindow.
161
162 If the m_wxwindow field is set, then all input to this widget is inter-
163 cepted and sent to the wxWidgets class. If not, all input to the widget
164 that gets pointed to by m_widget gets intercepted and sent to the class.
165
166 II)
167
168 The design of scrolling in wxWidgets is markedly different from that offered
169 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
170 clicking on a scrollbar belonging to scrolled window will inevitably move
171 the window. In wxWidgets, the scrollbar will only emit an event, send this
172 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
173 which actually moves the window and its subchildren. Note that GtkPizza
174 memorizes how much it has been scrolled but that wxWidgets forgets this
175 so that the two coordinates systems have to be kept in synch. This is done
176 in various places using the pizza->xoffset and pizza->yoffset values.
177
178 III)
179
180 Singularily the most broken code in GTK is the code that is supposes to
181 inform subwindows (child windows) about new positions. Very often, duplicate
182 events are sent without changes in size or position, equally often no
183 events are sent at all (All this is due to a bug in the GtkContainer code
184 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
185 GTK's own system and it simply waits for size events for toplevel windows
186 and then iterates down the respective size events to all window. This has
187 the disadvantage, that windows might get size events before the GTK widget
188 actually has the reported size. This doesn't normally pose any problem, but
189 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
190 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
191 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
192 window that is used for OpenGl output really has that size (as reported by
193 GTK).
194
195 IV)
196
197 If someone at some point of time feels the immense desire to have a look at,
198 change or attempt to optimse the Refresh() logic, this person will need an
199 intimate understanding of what a "draw" and what an "expose" events are and
200 what there are used for, in particular when used in connection with GTK's
201 own windowless widgets. Beware.
202
203 V)
204
205 Cursors, too, have been a constant source of pleasure. The main difficulty
206 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
207 for the parent. To prevent this from doing too much harm, I use idle time
208 to set the cursor over and over again, starting from the toplevel windows
209 and ending with the youngest generation (speaking of parent and child windows).
210 Also don't forget that cursors (like much else) are connected to GdkWindows,
211 not GtkWidgets and that the "window" field of a GtkWidget might very well
212 point to the GdkWindow of the parent widget (-> "window less widget") and
213 that the two obviously have very different meanings.
