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: | |
48 | // | |
49 | // the fifth modifier key (it depends on the modifier mapping of the X | |
50 | // server which key is interpreted as this modifier) | |
51 | // | |
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). | |
59 | // | |
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. | |

70 | /* | |
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. | |
76 | ||
77 | I) | |
78 | ||
79 | What does wxWindow do? It contains the common interface for the following | |
80 | jobs of its descendants: | |
81 | ||
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. | |
85 | ||
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. | |
92 | ||
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 | |
95 | as above. | |
96 | ||
97 | 4) Provide the entire mechanism for scrolling widgets. This actual inter- | |
98 | face for this is usually in wxScrolledWindow, but the GTK implementation | |
99 | is in this class. | |
100 | ||
101 | 5) A multitude of helper or extra methods for special purposes, such as | |
102 | Drag'n'Drop, managing validators etc. | |
103 | ||
104 | 6) Display a border (sunken, raised, simple or none). | |
105 | ||
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 | |
115 | this directory. | |
116 | ||
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) | |
124 | ||
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 | |
132 | the type wxPizza. | |
133 | ||
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. | |
140 | ||
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. | |
144 | ||
145 | II) | |
146 | ||
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. | |
156 | ||
157 | III) | |
158 | ||
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 | |
172 | GTK). | |
173 | ||
174 | IV) | |
175 | ||
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. | |
181 | ||
182 | V) | |
183 | ||
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, SetCursor calls | |
187 | GTKUpdateCursor, which will recursively re-set the cursors of all child windows. | |
188 | Also don't forget that cursors (like much else) are connected to GdkWindows, | |
189 | not GtkWidgets and that the "window" field of a GtkWidget might very well | |
190 | point to the GdkWindow of the parent widget (-> "window-less widget") and | |
191 | that the two obviously have very different meanings. | |
