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