57 /*
58 I have been asked several times about writing some documentation about
59 the GTK port of wxWindows, especially its internal structures. Obviously,
60 you cannot understand wxGTK without knowing a little about the GTK, but
61 some more information about what the wxWindow, which is the base class
62 for all other window classes, does seems required as well.
63
64 I)
65
66 What does wxWindow do? It contains the common interface for the following
67 jobs of its descendants:
68
69 1) Define the rudimentary behaviour common to all window classes, such as
70 resizing, intercepting user input (so as to make it possible to use these
71 events for special purposes in a derived class), window names etc.
72
73 2) Provide the possibility to contain and manage children, if the derived
74 class is allowed to contain children, which holds true for those window
75 classes which do not display a native GTK widget. To name them, these
76 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
77 work classes are a special case and are handled a bit differently from
78 the rest. The same holds true for the wxNotebook class.
79
80 3) Provide the possibility to draw into a client area of a window. This,
81 too, only holds true for classes that do not display a native GTK widget
82 as above.
83
84 4) Provide the entire mechanism for scrolling widgets. This actual inter-
85 face for this is usually in wxScrolledWindow, but the GTK implementation
86 is in this class.
87
88 5) A multitude of helper or extra methods for special purposes, such as
89 Drag'n'Drop, managing validators etc.
90
91 6) Display a border (sunken, raised, simple or none).
92
93 Normally one might expect, that one wxWindows window would always correspond
94 to one GTK widget. Under GTK, there is no such allround widget that has all
95 the functionality. Moreover, the GTK defines a client area as a different
96 widget from the actual widget you are handling. Last but not least some
97 special classes (e.g. wxFrame) handle different categories of widgets and
98 still have the possibility to draw something in the client area.
99 It was therefore required to write a special purpose GTK widget, that would
100 represent a client area in the sense of wxWindows capable to do the jobs
101 2), 3) and 4). I have written this class and it resides in win_gtk.c of
102 this directory.
103
104 All windows must have a widget, with which they interact with other under-
105 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
106 thw wxWindow class has a member variable called m_widget which holds a
107 pointer to this widget. When the window class represents a GTK native widget,
108 this is (in most cases) the only GTK widget the class manages. E.g. the
109 wxStatitText class handles only a GtkLabel widget a pointer to which you
110 can find in m_widget (defined in wxWindow)
111
112 When the class has a client area for drawing into and for containing children
113 it has to handle the client area widget (of the type GtkPizza, defined in
114 win_gtk.c), but there could be any number of widgets, handled by a class
115 The common rule for all windows is only, that the widget that interacts with
116 the rest of GTK must be referenced in m_widget and all other widgets must be
117 children of this widget on the GTK level. The top-most widget, which also
118 represents the client area, must be in the m_wxwindow field and must be of
119 the type GtkPizza.
120
121 As I said, the window classes that display a GTK native widget only have
122 one widget, so in the case of e.g. the wxButton class m_widget holds a
123 pointer to a GtkButton widget. But windows with client areas (for drawing
124 and children) have a m_widget field that is a pointer to a GtkScrolled-
125 Window and a m_wxwindow field that is pointer to a GtkPizza and this
126 one is (in the GTK sense) a child of the GtkScrolledWindow.
127
128 If the m_wxwindow field is set, then all input to this widget is inter-
129 cepted and sent to the wxWindows class. If not, all input to the widget
130 that gets pointed to by m_widget gets intercepted and sent to the class.
131
132 II)
133
134 The design of scrolling in wxWindows is markedly different from that offered
135 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
136 clicking on a scrollbar belonging to scrolled window will inevitably move
137 the window. In wxWindows, the scrollbar will only emit an event, send this
138 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
139 which actually moves the window and its subchildren. Note that GtkPizza
140 memorizes how much it has been scrolled but that wxWindows forgets this
141 so that the two coordinates systems have to be kept in synch. This is done
142 in various places using the pizza->xoffset and pizza->yoffset values.
143
144 III)
145
146 Singularily the most broken code in GTK is the code that is supposes to
147 inform subwindows (child windows) about new positions. Very often, duplicate
148 events are sent without changes in size or position, equally often no
149 events are sent at all (All this is due to a bug in the GtkContainer code
150 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
151 GTK's own system and it simply waits for size events for toplevel windows
152 and then iterates down the respective size events to all window. This has
153 the disadvantage, that windows might get size events before the GTK widget
154 actually has the reported size. This doesn't normally pose any problem, but
155 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
156 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
157 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
158 window that is used for OpenGl output really has that size (as reported by
159 GTK).
160
161 IV)
162
163 If someone at some point of time feels the immense desire to have a look at,
164 change or attempt to optimse the Refresh() logic, this person will need an
165 intimate understanding of what a "draw" and what an "expose" events are and
166 what there are used for, in particular when used in connection with GTK's
167 own windowless widgets. Beware.
168
169 V)
170
171 Cursors, too, have been a constant source of pleasure. The main difficulty
172 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
173 for the parent. To prevent this from doing too much harm, I use idle time
174 to set the cursor over and over again, starting from the toplevel windows
175 and ending with the youngest generation (speaking of parent and child windows).
176 Also don't forget that cursors (like much else) are connected to GdkWindows,
177 not GtkWidgets and that the "window" field of a GtkWidget might very well
178 point to the GdkWindow of the parent widget (-> "window less widget") and
179 that the two obviously have very different meanings.
