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