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