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. | |
