44 // GTK+ can reliably detect Meta key state only since 2.10 when
45 // GDK_META_MASK was introduced -- there wasn't any way to detect it
46 // in older versions. wxGTK used GDK_MOD2_MASK for this purpose, but
47 // GDK_MOD2_MASK is documented as:
49 // the fifth modifier key (it depends on the modifier mapping of the X
50 // server which key is interpreted as this modifier)
52 // In other words, it isn't guaranteed to map to Meta. This is a real
53 // problem: it is common to map NumLock to it (in fact, it's an exception
54 // if the X server _doesn't_ use it for NumLock). So the old code caused
55 // wxKeyEvent::MetaDown() to always return true as long as NumLock was on
56 // on many systems, which broke all applications using
57 // wxKeyEvent::GetModifiers() to check modifiers state (see e.g. here:
58 // http://tinyurl.com/56lsk2).
60 // Because of this, it's better to not detect Meta key state at all than
61 // to detect it incorrectly. Hence the following #define, which causes
62 // m_metaDown to be always set to false.
63 #define GDK_META_MASK 0

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