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