53 /*
54 I have been asked several times about writing some documentation about
55 the GTK port of wxWindows, especially its internal structures. Obviously,
56 you cannot understand wxGTK without knowing a little about the GTK, but
57 some more information about what the wxWindow, which is the base class
58 for all other window classes, does seems required as well.
59
60 I)
61
62 What does wxWindow do? It contains the common interface for the following
63 jobs of its descendants:
64
65 1) Define the rudimentary behaviour common to all window classes, such as
66 resizing, intercepting user input (so as to make it possible to use these
67 events for special purposes in a derived class), window names etc.
68
69 2) Provide the possibility to contain and manage children, if the derived
70 class is allowed to contain children, which holds true for those window
71 classes which do not display a native GTK widget. To name them, these
72 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
73 work classes are a special case and are handled a bit differently from
74 the rest. The same holds true for the wxNotebook class.
75
76 3) Provide the possibility to draw into a client area of a window. This,
77 too, only holds true for classes that do not display a native GTK widget
78 as above.
79
80 4) Provide the entire mechanism for scrolling widgets. This actual inter-
81 face for this is usually in wxScrolledWindow, but the GTK implementation
82 is in this class.
83
84 5) A multitude of helper or extra methods for special purposes, such as
85 Drag'n'Drop, managing validators etc.
86
87 6) Display a border (sunken, raised, simple or none).
88
89 Normally one might expect, that one wxWindows window would always correspond
90 to one GTK widget. Under GTK, there is no such allround widget that has all
91 the functionality. Moreover, the GTK defines a client area as a different
92 widget from the actual widget you are handling. Last but not least some
93 special classes (e.g. wxFrame) handle different categories of widgets and
94 still have the possibility to draw something in the client area.
95 It was therefore required to write a special purpose GTK widget, that would
96 represent a client area in the sense of wxWindows capable to do the jobs
97 2), 3) and 4). I have written this class and it resides in win_gtk.c of
98 this directory.
99
100 All windows must have a widget, with which they interact with other under-
101 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
102 thw wxWindow class has a member variable called m_widget which holds a
103 pointer to this widget. When the window class represents a GTK native widget,
104 this is (in most cases) the only GTK widget the class manages. E.g. the
105 wxStatitText class handles only a GtkLabel widget a pointer to which you
106 can find in m_widget (defined in wxWindow)
107
108 When the class has a client area for drawing into and for containing children
109 it has to handle the client area widget (of the type GtkMyFixed, defined in
110 win_gtk.c), but there could be any number of widgets, handled by a class
111 The common rule for all windows is only, that the widget that interacts with
112 the rest of GTK must be referenced in m_widget and all other widgets must be
113 children of this widget on the GTK level. The top-most widget, which also
114 represents the client area, must be in the m_wxwindow field and must be of
115 the type GtkMyFixed.
116
117 As I said, the window classes that display a GTK native widget only have
118 one widget, so in the case of e.g. the wxButton class m_widget holds a
119 pointer to a GtkButton widget. But windows with client areas (for drawing
120 and children) have a m_widget field that is a pointer to a GtkScrolled-
121 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
122 one is (in the GTK sense) a child of the GtkScrolledWindow.
123
124 If the m_wxwindow field is set, then all input to this widget is inter-
125 cepted and sent to the wxWindows class. If not, all input to the widget
126 that gets pointed to by m_widget gets intercepted and sent to the class.
127
128 II)
129
130 The design of scrolling in wxWindows is markedly different from that offered
131 by the GTK itself and therefore we cannot simply take it as it is. In GTK,
132 clicking on a scrollbar belonging to scrolled window will inevitably move
133 the window. In wxWindows, the scrollbar will only emit an event, send this
134 to (normally) a wxScrolledWindow and that class will call ScrollWindow()
135 which actually moves the window and its subchildren. Note that GtkMyFixed
136 memorizes how much it has been scrolled but that wxWindows forgets this
137 so that the two coordinates systems have to be kept in synch. This is done
138 in various places using the myfixed->xoffset and myfixed->yoffset values.
139
140 III)
141
142 Singularily the most broken code in GTK is the code that is supposes to
143 inform subwindows (child windows) about new positions. Very often, duplicate
144 events are sent without changes in size or position, equally often no
145 events are sent at all (All this is due to a bug in the GtkContainer code
146 which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
147 GTK's own system and it simply waits for size events for toplevel windows
148 and then iterates down the respective size events to all window. This has
149 the disadvantage, that windows might get size events before the GTK widget
150 actually has the reported size. This doesn't normally pose any problem, but
151 the OpenGl drawing routines rely on correct behaviour. Therefore, I have
152 added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
153 i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
154 window that is used for OpenGl output really has that size (as reported by
155 GTK).
156
157 IV)
158
159 If someone at some point of time feels the immense desire to have a look at,
160 change or attempt to optimse the Refresh() logic, this person will need an
161 intimate understanding of what a "draw" and what an "expose" events are and
162 what there are used for, in particular when used in connection with GTK's
163 own windowless widgets. Beware.
164
165 V)
166
167 Cursors, too, have been a constant source of pleasure. The main difficulty
168 is that a GdkWindow inherits a cursor if the programmer sets a new cursor
169 for the parent. To prevent this from doing too much harm, I use idle time
170 to set the cursor over and over again, starting from the toplevel windows
171 and ending with the youngest generation (speaking of parent and child windows).
172 Also don't forget that cursors (like much else) are connected to GdkWindows,
173 not GtkWidgets and that the "window" field of a GtkWidget might very well
174 point to the GdkWindow of the parent widget (-> "window less widget") and
175 that the two obviously have very different meanings.
