| 72 | /* |
| 73 | I have been asked several times about writing some documentation about |
| 74 | the GTK port of wxWidgets, especially its internal structures. Obviously, |
| 75 | you cannot understand wxGTK without knowing a little about the GTK, but |
| 76 | some more information about what the wxWindow, which is the base class |
| 77 | for all other window classes, does seems required as well. |
| 78 | |
| 79 | I) |
| 80 | |
| 81 | What does wxWindow do? It contains the common interface for the following |
| 82 | jobs of its descendants: |
| 83 | |
| 84 | 1) Define the rudimentary behaviour common to all window classes, such as |
| 85 | resizing, intercepting user input (so as to make it possible to use these |
| 86 | events for special purposes in a derived class), window names etc. |
| 87 | |
| 88 | 2) Provide the possibility to contain and manage children, if the derived |
| 89 | class is allowed to contain children, which holds true for those window |
| 90 | classes which do not display a native GTK widget. To name them, these |
| 91 | classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame- |
| 92 | work classes are a special case and are handled a bit differently from |
| 93 | the rest. The same holds true for the wxNotebook class. |
| 94 | |
| 95 | 3) Provide the possibility to draw into a client area of a window. This, |
| 96 | too, only holds true for classes that do not display a native GTK widget |
| 97 | as above. |
| 98 | |
| 99 | 4) Provide the entire mechanism for scrolling widgets. This actual inter- |
| 100 | face for this is usually in wxScrolledWindow, but the GTK implementation |
| 101 | is in this class. |
| 102 | |
| 103 | 5) A multitude of helper or extra methods for special purposes, such as |
| 104 | Drag'n'Drop, managing validators etc. |
| 105 | |
| 106 | 6) Display a border (sunken, raised, simple or none). |
| 107 | |
| 108 | Normally one might expect, that one wxWidgets window would always correspond |
| 109 | to one GTK widget. Under GTK, there is no such allround widget that has all |
| 110 | the functionality. Moreover, the GTK defines a client area as a different |
| 111 | widget from the actual widget you are handling. Last but not least some |
| 112 | special classes (e.g. wxFrame) handle different categories of widgets and |
| 113 | still have the possibility to draw something in the client area. |
| 114 | It was therefore required to write a special purpose GTK widget, that would |
| 115 | represent a client area in the sense of wxWidgets capable to do the jobs |
| 116 | 2), 3) and 4). I have written this class and it resides in win_gtk.c of |
| 117 | this directory. |
| 118 | |
| 119 | All windows must have a widget, with which they interact with other under- |
| 120 | lying GTK widgets. It is this widget, e.g. that has to be resized etc and |
| 121 | the wxWindow class has a member variable called m_widget which holds a |
| 122 | pointer to this widget. When the window class represents a GTK native widget, |
| 123 | this is (in most cases) the only GTK widget the class manages. E.g. the |
| 124 | wxStaticText class handles only a GtkLabel widget a pointer to which you |
| 125 | can find in m_widget (defined in wxWindow) |
| 126 | |
| 127 | When the class has a client area for drawing into and for containing children |
| 128 | it has to handle the client area widget (of the type GtkPizza, defined in |
| 129 | win_gtk.c), but there could be any number of widgets, handled by a class |
| 130 | The common rule for all windows is only, that the widget that interacts with |
| 131 | the rest of GTK must be referenced in m_widget and all other widgets must be |
| 132 | children of this widget on the GTK level. The top-most widget, which also |
| 133 | represents the client area, must be in the m_wxwindow field and must be of |
| 134 | the type GtkPizza. |
| 135 | |
| 136 | As I said, the window classes that display a GTK native widget only have |
| 137 | one widget, so in the case of e.g. the wxButton class m_widget holds a |
| 138 | pointer to a GtkButton widget. But windows with client areas (for drawing |
| 139 | and children) have a m_widget field that is a pointer to a GtkScrolled- |
| 140 | Window and a m_wxwindow field that is pointer to a GtkPizza and this |
| 141 | one is (in the GTK sense) a child of the GtkScrolledWindow. |
| 142 | |
| 143 | If the m_wxwindow field is set, then all input to this widget is inter- |
| 144 | cepted and sent to the wxWidgets class. If not, all input to the widget |
| 145 | that gets pointed to by m_widget gets intercepted and sent to the class. |
| 146 | |
| 147 | II) |
| 148 | |
| 149 | The design of scrolling in wxWidgets is markedly different from that offered |
| 150 | by the GTK itself and therefore we cannot simply take it as it is. In GTK, |
| 151 | clicking on a scrollbar belonging to scrolled window will inevitably move |
| 152 | the window. In wxWidgets, the scrollbar will only emit an event, send this |
| 153 | to (normally) a wxScrolledWindow and that class will call ScrollWindow() |
| 154 | which actually moves the window and its subchildren. Note that GtkPizza |
| 155 | memorizes how much it has been scrolled but that wxWidgets forgets this |
| 156 | so that the two coordinates systems have to be kept in synch. This is done |
| 157 | in various places using the pizza->xoffset and pizza->yoffset values. |
| 158 | |
| 159 | III) |
| 160 | |
| 161 | Singularily the most broken code in GTK is the code that is supposed to |
| 162 | inform subwindows (child windows) about new positions. Very often, duplicate |
| 163 | events are sent without changes in size or position, equally often no |
| 164 | events are sent at all (All this is due to a bug in the GtkContainer code |
| 165 | which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores |
| 166 | GTK's own system and it simply waits for size events for toplevel windows |
| 167 | and then iterates down the respective size events to all window. This has |
| 168 | the disadvantage that windows might get size events before the GTK widget |
| 169 | actually has the reported size. This doesn't normally pose any problem, but |
| 170 | the OpenGL drawing routines rely on correct behaviour. Therefore, I have |
| 171 | added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas, |
| 172 | i.e. the wxGLCanvas will emit a size event, when (and not before) the X11 |
| 173 | window that is used for OpenGL output really has that size (as reported by |
| 174 | GTK). |
| 175 | |
| 176 | IV) |
| 177 | |
| 178 | If someone at some point of time feels the immense desire to have a look at, |
| 179 | change or attempt to optimise the Refresh() logic, this person will need an |
| 180 | intimate understanding of what "draw" and "expose" events are and what |
| 181 | they are used for, in particular when used in connection with GTK's |
| 182 | own windowless widgets. Beware. |
| 183 | |
| 184 | V) |
| 185 | |
| 186 | Cursors, too, have been a constant source of pleasure. The main difficulty |
| 187 | is that a GdkWindow inherits a cursor if the programmer sets a new cursor |
| 188 | for the parent. To prevent this from doing too much harm, I use idle time |
| 189 | to set the cursor over and over again, starting from the toplevel windows |
| 190 | and ending with the youngest generation (speaking of parent and child windows). |
| 191 | Also don't forget that cursors (like much else) are connected to GdkWindows, |
| 192 | not GtkWidgets and that the "window" field of a GtkWidget might very well |
| 193 | point to the GdkWindow of the parent widget (-> "window-less widget") and |
| 194 | that the two obviously have very different meanings. |
