72 /*
73 I have been asked several times about writing some documentation about
74 the GTK port of wxWindows, especially its internal structures. Obviously,
75 you cannot understand wxGTK without knowing a little about the GTK, but
76 some more information about what the wxWindow, which is the base class
77 for all other window classes, does seems required as well.
78
79 I)
80
81 What does wxWindow do? It contains the common interface for the following
82 jobs of its descendants:
83
84 1) Define the rudimentary behaviour common to all window classes, such as
85 resizing, intercepting user input (so as to make it possible to use these
86 events for special purposes in a derived class), window names etc.
87
88 2) Provide the possibility to contain and manage children, if the derived
89 class is allowed to contain children, which holds true for those window
90 classes which do not display a native GTK widget. To name them, these
91 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
92 work classes are a special case and are handled a bit differently from
93 the rest. The same holds true for the wxNotebook class.
94
95 3) Provide the possibility to draw into a client area of a window. This,
96 too, only holds true for classes that do not display a native GTK widget
97 as above.
98
99 4) Provide the entire mechanism for scrolling widgets. This actual inter-
100 face for this is usually in wxScrolledWindow, but the GTK implementation
101 is in this class.
102
103 5) A multitude of helper or extra methods for special purposes, such as
104 Drag'n'Drop, managing validators etc.
105
106 6) Display a border (sunken, raised, simple or none).
107
108 Normally one might expect, that one wxWindows window would always correspond
109 to one GTK widget. Under GTK, there is no such allround widget that has all
110 the functionality. Moreover, the GTK defines a client area as a different
111 widget from the actual widget you are handling. Last but not least some
112 special classes (e.g. wxFrame) handle different categories of widgets and
113 still have the possibility to draw something in the client area.
114 It was therefore required to write a special purpose GTK widget, that would
115 represent a client area in the sense of wxWindows capable to do the jobs
116 2), 3) and 4). I have written this class and it resides in win_gtk.c of
117 this directory.
118
119 All windows must have a widget, with which they interact with other under-
120 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
121 thw wxWindow class has a member variable called m_widget which holds a
122 pointer to this widget. When the window class represents a GTK native widget,
123 this is (in most cases) the only GTK widget the class manages. E.g. the
124 wxStatitText class handles only a GtkLabel widget a pointer to which you
125 can find in m_widget (defined in wxWindow)
126
127 When the class has a client area for drawing into and for containing children
128 it has to handle the client area widget (of the type GtkPizza, defined in
129 win_gtk.c), but there could be any number of widgets, handled by a class
130 The common rule for all windows is only, that the widget that interacts with
131 the rest of GTK must be referenced in m_widget and all other widgets must be
132 children of this widget on the GTK level. The top-most widget, which also
133 represents the client area, must be in the m_wxwindow field and must be of
134 the type GtkPizza.
135
136 As I said, the window classes that display a GTK native widget only have
137 one widget, so in the case of e.g. the wxButton class m_widget holds a
138 pointer to a GtkButton widget. But windows with client areas (for drawing
139 and children) have a m_widget field that is a pointer to a GtkScrolled-
140 Window and a m_wxwindow field that is pointer to a GtkPizza and this
141 one is (in the GTK sense) a child of the GtkScrolledWindow.
142
143 If the m_wxwindow field is set, then all input to this widget is inter-
144 cepted and sent to the wxWindows class. If not, all input to the widget
145 that gets pointed to by m_widget gets intercepted and sent to the class.
146
147 II)
148
149 The design of scrolling in wxWindows is markedly different from that offered
150 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
151 clicking on a scrollbar belonging to scrolled window will inevitably move
152 the window. In wxWindows, the scrollbar will only emit an event, send this
153 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
154 which actually moves the window and its subchildren. Note that GtkPizza
155 memorizes how much it has been scrolled but that wxWindows forgets this
156 so that the two coordinates systems have to be kept in synch. This is done
157 in various places using the pizza->xoffset and pizza->yoffset values.
158
159 III)
160
161 Singularily the most broken code in GTK is the code that is supposes to
162 inform subwindows (child windows) about new positions. Very often, duplicate
163 events are sent without changes in size or position, equally often no
164 events are sent at all (All this is due to a bug in the GtkContainer code
165 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
166 GTK's own system and it simply waits for size events for toplevel windows
167 and then iterates down the respective size events to all window. This has
168 the disadvantage, that windows might get size events before the GTK widget
169 actually has the reported size. This doesn't normally pose any problem, but
170 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
171 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
172 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
173 window that is used for OpenGl output really has that size (as reported by
174 GTK).
175
176 IV)
177
178 If someone at some point of time feels the immense desire to have a look at,
179 change or attempt to optimse the Refresh() logic, this person will need an
180 intimate understanding of what a "draw" and what an "expose" events are and
181 what there are used for, in particular when used in connection with GTK's
182 own windowless widgets. Beware.
183
184 V)
185
186 Cursors, too, have been a constant source of pleasure. The main difficulty
187 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
188 for the parent. To prevent this from doing too much harm, I use idle time
189 to set the cursor over and over again, starting from the toplevel windows
190 and ending with the youngest generation (speaking of parent and child windows).
191 Also don't forget that cursors (like much else) are connected to GdkWindows,
192 not GtkWidgets and that the "window" field of a GtkWidget might very well
193 point to the GdkWindow of the parent widget (-> "window less widget") and
194 that the two obviously have very different meanings.
