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