88 /*
89 I have been asked several times about writing some documentation about
90 the GTK port of wxWindows, especially its internal structures. Obviously,
91 you cannot understand wxGTK without knowing a little about the GTK, but
92 some more information about what the wxWindow, which is the base class
93 for all other window classes, does seems required as well.
94
95 I)
96
97 What does wxWindow do? It contains the common interface for the following
98 jobs of its descendants:
99
100 1) Define the rudimentary behaviour common to all window classes, such as
101 resizing, intercepting user input (so as to make it possible to use these
102 events for special purposes in a derived class), window names etc.
103
104 2) Provide the possibility to contain and manage children, if the derived
105 class is allowed to contain children, which holds true for those window
106 classes which do not display a native GTK widget. To name them, these
107 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
108 work classes are a special case and are handled a bit differently from
109 the rest. The same holds true for the wxNotebook class.
110
111 3) Provide the possibility to draw into a client area of a window. This,
112 too, only holds true for classes that do not display a native GTK widget
113 as above.
114
115 4) Provide the entire mechanism for scrolling widgets. This actual inter-
116 face for this is usually in wxScrolledWindow, but the GTK implementation
117 is in this class.
118
119 5) A multitude of helper or extra methods for special purposes, such as
120 Drag'n'Drop, managing validators etc.
121
122 6) Display a border (sunken, raised, simple or none).
123
124 Normally one might expect, that one wxWindows window would always correspond
125 to one GTK widget. Under GTK, there is no such allround widget that has all
126 the functionality. Moreover, the GTK defines a client area as a different
127 widget from the actual widget you are handling. Last but not least some
128 special classes (e.g. wxFrame) handle different categories of widgets and
129 still have the possibility to draw something in the client area.
130 It was therefore required to write a special purpose GTK widget, that would
131 represent a client area in the sense of wxWindows capable to do the jobs
132 2), 3) and 4). I have written this class and it resides in win_gtk.c of
133 this directory.
134
135 All windows must have a widget, with which they interact with other under-
136 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
137 thw wxWindow class has a member variable called m_widget which holds a
138 pointer to this widget. When the window class represents a GTK native widget,
139 this is (in most cases) the only GTK widget the class manages. E.g. the
140 wxStatitText class handles only a GtkLabel widget a pointer to which you
141 can find in m_widget (defined in wxWindow)
142
143 When the class has a client area for drawing into and for containing children
144 it has to handle the client area widget (of the type GtkPizza, defined in
145 win_gtk.c), but there could be any number of widgets, handled by a class
146 The common rule for all windows is only, that the widget that interacts with
147 the rest of GTK must be referenced in m_widget and all other widgets must be
148 children of this widget on the GTK level. The top-most widget, which also
149 represents the client area, must be in the m_wxwindow field and must be of
150 the type GtkPizza.
151
152 As I said, the window classes that display a GTK native widget only have
153 one widget, so in the case of e.g. the wxButton class m_widget holds a
154 pointer to a GtkButton widget. But windows with client areas (for drawing
155 and children) have a m_widget field that is a pointer to a GtkScrolled-
156 Window and a m_wxwindow field that is pointer to a GtkPizza and this
157 one is (in the GTK sense) a child of the GtkScrolledWindow.
158
159 If the m_wxwindow field is set, then all input to this widget is inter-
160 cepted and sent to the wxWindows class. If not, all input to the widget
161 that gets pointed to by m_widget gets intercepted and sent to the class.
162
163 II)
164
165 The design of scrolling in wxWindows is markedly different from that offered
166 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
167 clicking on a scrollbar belonging to scrolled window will inevitably move
168 the window. In wxWindows, the scrollbar will only emit an event, send this
169 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
170 which actually moves the window and its subchildren. Note that GtkPizza
171 memorizes how much it has been scrolled but that wxWindows forgets this
172 so that the two coordinates systems have to be kept in synch. This is done
173 in various places using the pizza->xoffset and pizza->yoffset values.
174
175 III)
176
177 Singularily the most broken code in GTK is the code that is supposes to
178 inform subwindows (child windows) about new positions. Very often, duplicate
179 events are sent without changes in size or position, equally often no
180 events are sent at all (All this is due to a bug in the GtkContainer code
181 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
182 GTK's own system and it simply waits for size events for toplevel windows
183 and then iterates down the respective size events to all window. This has
184 the disadvantage, that windows might get size events before the GTK widget
185 actually has the reported size. This doesn't normally pose any problem, but
186 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
187 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
188 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
189 window that is used for OpenGl output really has that size (as reported by
190 GTK).
191
192 IV)
193
194 If someone at some point of time feels the immense desire to have a look at,
195 change or attempt to optimse the Refresh() logic, this person will need an
196 intimate understanding of what a "draw" and what an "expose" events are and
197 what there are used for, in particular when used in connection with GTK's
198 own windowless widgets. Beware.
199
200 V)
201
202 Cursors, too, have been a constant source of pleasure. The main difficulty
203 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
204 for the parent. To prevent this from doing too much harm, I use idle time
205 to set the cursor over and over again, starting from the toplevel windows
206 and ending with the youngest generation (speaking of parent and child windows).
207 Also don't forget that cursors (like much else) are connected to GdkWindows,
208 not GtkWidgets and that the "window" field of a GtkWidget might very well
209 point to the GdkWindow of the parent widget (-> "window less widget") and
210 that the two obviously have very different meanings.
