88 | /* | |
89 | I have been asked several times about writing some documentation about | |
77ffb593 | 90 | the GTK port of wxWidgets, especially its internal structures. Obviously, |
868a2826 | 91 | you cannot understand wxGTK without knowing a little about the GTK, but |
47d67540 | 92 | some more information about what the wxWindow, which is the base class |
868a2826 | 93 | for all other window classes, does seems required as well. |
47d67540 | 94 | |
30760ce7 RR |
95 | I) |
96 | ||
868a2826 | 97 | What does wxWindow do? It contains the common interface for the following |
e380f72b | 98 | jobs of its descendants: |
47d67540 | 99 | |
868a2826 | 100 | 1) Define the rudimentary behaviour common to all window classes, such as |
e380f72b RR |
101 | resizing, intercepting user input (so as to make it possible to use these |
102 | events for special purposes in a derived class), window names etc. | |
868a2826 RR |
103 | |
104 | 2) Provide the possibility to contain and manage children, if the derived | |
105 | class is allowed to contain children, which holds true for those window | |
e380f72b | 106 | classes which do not display a native GTK widget. To name them, these |
868a2826 | 107 | classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame- |
47d67540 | 108 | work classes are a special case and are handled a bit differently from |
e380f72b | 109 | the rest. The same holds true for the wxNotebook class. |
47d67540 | 110 | |
868a2826 RR |
111 | 3) Provide the possibility to draw into a client area of a window. This, |
112 | too, only holds true for classes that do not display a native GTK widget | |
113 | as above. | |
47d67540 | 114 | |
e380f72b RR |
115 | 4) Provide the entire mechanism for scrolling widgets. This actual inter- |
116 | face for this is usually in wxScrolledWindow, but the GTK implementation | |
868a2826 | 117 | is in this class. |
47d67540 | 118 | |
868a2826 RR |
119 | 5) A multitude of helper or extra methods for special purposes, such as |
120 | Drag'n'Drop, managing validators etc. | |
47d67540 | 121 | |
30760ce7 RR |
122 | 6) Display a border (sunken, raised, simple or none). |
123 | ||
77ffb593 | 124 | Normally one might expect, that one wxWidgets window would always correspond |
6a17b868 | 125 | to one GTK widget. Under GTK, there is no such all-round widget that has all |
868a2826 RR |
126 | the functionality. Moreover, the GTK defines a client area as a different |
127 | widget from the actual widget you are handling. Last but not least some | |
128 | special classes (e.g. wxFrame) handle different categories of widgets and | |
129 | still have the possibility to draw something in the client area. | |
130 | It was therefore required to write a special purpose GTK widget, that would | |
77ffb593 | 131 | represent a client area in the sense of wxWidgets capable to do the jobs |
868a2826 RR |
132 | 2), 3) and 4). I have written this class and it resides in win_gtk.c of |
133 | this directory. | |
47d67540 | 134 | |
868a2826 | 135 | All windows must have a widget, with which they interact with other under- |
e380f72b | 136 | lying GTK widgets. It is this widget, e.g. that has to be resized etc and |
90e572f1 | 137 | the wxWindow class has a member variable called m_widget which holds a |
e380f72b RR |
138 | pointer to this widget. When the window class represents a GTK native widget, |
139 | this is (in most cases) the only GTK widget the class manages. E.g. the | |
f8e045e2 | 140 | wxStaticText class handles only a GtkLabel widget a pointer to which you |
e380f72b | 141 | can find in m_widget (defined in wxWindow) |
8bbe427f | 142 | |
e380f72b | 143 | When the class has a client area for drawing into and for containing children |
da048e3d | 144 | it has to handle the client area widget (of the type GtkPizza, defined in |
8bbe427f VZ |
145 | win_gtk.c), but there could be any number of widgets, handled by a class |
146 | The common rule for all windows is only, that the widget that interacts with | |
147 | the rest of GTK must be referenced in m_widget and all other widgets must be | |
148 | children of this widget on the GTK level. The top-most widget, which also | |
149 | represents the client area, must be in the m_wxwindow field and must be of | |
da048e3d | 150 | the type GtkPizza. |
47d67540 | 151 | |
868a2826 RR |
152 | As I said, the window classes that display a GTK native widget only have |
153 | one widget, so in the case of e.g. the wxButton class m_widget holds a | |
154 | pointer to a GtkButton widget. But windows with client areas (for drawing | |
155 | and children) have a m_widget field that is a pointer to a GtkScrolled- | |
da048e3d | 156 | Window and a m_wxwindow field that is pointer to a GtkPizza and this |
868a2826 | 157 | one is (in the GTK sense) a child of the GtkScrolledWindow. |
47d67540 | 158 | |
868a2826 | 159 | If the m_wxwindow field is set, then all input to this widget is inter- |
77ffb593 | 160 | cepted and sent to the wxWidgets class. If not, all input to the widget |
868a2826 | 161 | that gets pointed to by m_widget gets intercepted and sent to the class. |
148cd9b6 | 162 | |
30760ce7 | 163 | II) |
148cd9b6 | 164 | |
77ffb593 | 165 | The design of scrolling in wxWidgets is markedly different from that offered |
30760ce7 RR |
166 | by the GTK itself and therefore we cannot simply take it as it is. In GTK, |
167 | clicking on a scrollbar belonging to scrolled window will inevitably move | |
77ffb593 | 168 | the window. In wxWidgets, the scrollbar will only emit an event, send this |
30760ce7 | 169 | to (normally) a wxScrolledWindow and that class will call ScrollWindow() |
6a17b868 | 170 | which actually moves the window and its sub-windows. Note that GtkPizza |
77ffb593 | 171 | memorizes how much it has been scrolled but that wxWidgets forgets this |
30760ce7 | 172 | so that the two coordinates systems have to be kept in synch. This is done |
da048e3d | 173 | in various places using the pizza->xoffset and pizza->yoffset values. |
148cd9b6 VZ |
174 | |
175 | III) | |
176 | ||
6a17b868 | 177 | Singularly the most broken code in GTK is the code that is supposed to |
30760ce7 RR |
178 | inform subwindows (child windows) about new positions. Very often, duplicate |
179 | events are sent without changes in size or position, equally often no | |
180 | events are sent at all (All this is due to a bug in the GtkContainer code | |
181 | which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores | |
182 | GTK's own system and it simply waits for size events for toplevel windows | |
183 | and then iterates down the respective size events to all window. This has | |
90e572f1 | 184 | the disadvantage that windows might get size events before the GTK widget |
30760ce7 | 185 | actually has the reported size. This doesn't normally pose any problem, but |
90e572f1 | 186 | the OpenGL drawing routines rely on correct behaviour. Therefore, I have |
30760ce7 RR |
187 | added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas, |
188 | i.e. the wxGLCanvas will emit a size event, when (and not before) the X11 | |
90e572f1 | 189 | window that is used for OpenGL output really has that size (as reported by |
30760ce7 RR |
190 | GTK). |
191 | ||
192 | IV) | |
148cd9b6 | 193 | |
30760ce7 | 194 | If someone at some point of time feels the immense desire to have a look at, |
90e572f1 MR |
195 | change or attempt to optimise the Refresh() logic, this person will need an |
196 | intimate understanding of what "draw" and "expose" events are and what | |
197 | they are used for, in particular when used in connection with GTK's | |
30760ce7 | 198 | own windowless widgets. Beware. |
148cd9b6 | 199 | |
30760ce7 | 200 | V) |
148cd9b6 | 201 | |
30760ce7 RR |
202 | Cursors, too, have been a constant source of pleasure. The main difficulty |
203 | is that a GdkWindow inherits a cursor if the programmer sets a new cursor | |
204 | for the parent. To prevent this from doing too much harm, I use idle time | |
205 | to set the cursor over and over again, starting from the toplevel windows | |
206 | and ending with the youngest generation (speaking of parent and child windows). | |
207 | Also don't forget that cursors (like much else) are connected to GdkWindows, | |
208 | not GtkWidgets and that the "window" field of a GtkWidget might very well | |
90e572f1 | 209 | point to the GdkWindow of the parent widget (-> "window-less widget") and |
30760ce7 | 210 | that the two obviously have very different meanings. |
