83 /*
84 I have been asked several times about writing some documentation about
85 the GTK port of wxWindows, especially its internal structures. Obviously,
86 you cannot understand wxGTK without knowing a little about the GTK, but
87 some more information about what the wxWindow, which is the base class
88 for all other window classes, does seems required as well.
89
90 I)
91
92 What does wxWindow do? It contains the common interface for the following
93 jobs of its descendants:
94
95 1) Define the rudimentary behaviour common to all window classes, such as
96 resizing, intercepting user input (so as to make it possible to use these
97 events for special purposes in a derived class), window names etc.
98
99 2) Provide the possibility to contain and manage children, if the derived
100 class is allowed to contain children, which holds true for those window
101 classes which do not display a native GTK widget. To name them, these
102 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
103 work classes are a special case and are handled a bit differently from
104 the rest. The same holds true for the wxNotebook class.
105
106 3) Provide the possibility to draw into a client area of a window. This,
107 too, only holds true for classes that do not display a native GTK widget
108 as above.
109
110 4) Provide the entire mechanism for scrolling widgets. This actual inter-
111 face for this is usually in wxScrolledWindow, but the GTK implementation
112 is in this class.
113
114 5) A multitude of helper or extra methods for special purposes, such as
115 Drag'n'Drop, managing validators etc.
116
117 6) Display a border (sunken, raised, simple or none).
118
119 Normally one might expect, that one wxWindows window would always correspond
120 to one GTK widget. Under GTK, there is no such allround widget that has all
121 the functionality. Moreover, the GTK defines a client area as a different
122 widget from the actual widget you are handling. Last but not least some
123 special classes (e.g. wxFrame) handle different categories of widgets and
124 still have the possibility to draw something in the client area.
125 It was therefore required to write a special purpose GTK widget, that would
126 represent a client area in the sense of wxWindows capable to do the jobs
127 2), 3) and 4). I have written this class and it resides in win_gtk.c of
128 this directory.
129
130 All windows must have a widget, with which they interact with other under-
131 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
132 thw wxWindow class has a member variable called m_widget which holds a
133 pointer to this widget. When the window class represents a GTK native widget,
134 this is (in most cases) the only GTK widget the class manages. E.g. the
135 wxStatitText class handles only a GtkLabel widget a pointer to which you
136 can find in m_widget (defined in wxWindow)
137
138 When the class has a client area for drawing into and for containing children
139 it has to handle the client area widget (of the type GtkPizza, defined in
140 win_gtk.c), but there could be any number of widgets, handled by a class
141 The common rule for all windows is only, that the widget that interacts with
142 the rest of GTK must be referenced in m_widget and all other widgets must be
143 children of this widget on the GTK level. The top-most widget, which also
144 represents the client area, must be in the m_wxwindow field and must be of
145 the type GtkPizza.
146
147 As I said, the window classes that display a GTK native widget only have
148 one widget, so in the case of e.g. the wxButton class m_widget holds a
149 pointer to a GtkButton widget. But windows with client areas (for drawing
150 and children) have a m_widget field that is a pointer to a GtkScrolled-
151 Window and a m_wxwindow field that is pointer to a GtkPizza and this
152 one is (in the GTK sense) a child of the GtkScrolledWindow.
153
154 If the m_wxwindow field is set, then all input to this widget is inter-
155 cepted and sent to the wxWindows class. If not, all input to the widget
156 that gets pointed to by m_widget gets intercepted and sent to the class.
157
158 II)
159
160 The design of scrolling in wxWindows is markedly different from that offered
161 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
162 clicking on a scrollbar belonging to scrolled window will inevitably move
163 the window. In wxWindows, the scrollbar will only emit an event, send this
164 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
165 which actually moves the window and its subchildren. Note that GtkPizza
166 memorizes how much it has been scrolled but that wxWindows forgets this
167 so that the two coordinates systems have to be kept in synch. This is done
168 in various places using the pizza->xoffset and pizza->yoffset values.
169
170 III)
171
172 Singularily the most broken code in GTK is the code that is supposes to
173 inform subwindows (child windows) about new positions. Very often, duplicate
174 events are sent without changes in size or position, equally often no
175 events are sent at all (All this is due to a bug in the GtkContainer code
176 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
177 GTK's own system and it simply waits for size events for toplevel windows
178 and then iterates down the respective size events to all window. This has
179 the disadvantage, that windows might get size events before the GTK widget
180 actually has the reported size. This doesn't normally pose any problem, but
181 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
182 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
183 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
184 window that is used for OpenGl output really has that size (as reported by
185 GTK).
186
187 IV)
188
189 If someone at some point of time feels the immense desire to have a look at,
190 change or attempt to optimse the Refresh() logic, this person will need an
191 intimate understanding of what a "draw" and what an "expose" events are and
192 what there are used for, in particular when used in connection with GTK's
193 own windowless widgets. Beware.
194
195 V)
196
197 Cursors, too, have been a constant source of pleasure. The main difficulty
198 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
199 for the parent. To prevent this from doing too much harm, I use idle time
200 to set the cursor over and over again, starting from the toplevel windows
201 and ending with the youngest generation (speaking of parent and child windows).
202 Also don't forget that cursors (like much else) are connected to GdkWindows,
203 not GtkWidgets and that the "window" field of a GtkWidget might very well
204 point to the GdkWindow of the parent widget (-> "window less widget") and
205 that the two obviously have very different meanings.
