53 | /* | |
54 | I have been asked several times about writing some documentation about | |
55 | the GTK port of wxWindows, especially its internal structures. Obviously, | |
56 | you cannot understand wxGTK without knowing a little about the GTK, but | |
57 | some more information about what the wxWindow, which is the base class | |
58 | for all other window classes, does seems required as well. | |
59 | ||
60 | What does wxWindow do? It contains the common interface for the following | |
61 | jobs of its descendants: | |
62 | ||
63 | 1) Define the rudimentary behaviour common to all window classes, such as | |
64 | resizing, intercepting user input (so as to make it possible to use these | |
65 | events for special purposes in a derived class), window names etc. | |
66 | ||
67 | 2) Provide the possibility to contain and manage children, if the derived | |
68 | class is allowed to contain children, which holds true for those window | |
69 | classes which do not display a native GTK widget. To name them, these | |
70 | classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame- | |
71 | work classes are a special case and are handled a bit differently from | |
72 | the rest. The same holds true for the wxNotebook class. | |
73 | ||
74 | 3) Provide the possibility to draw into a client area of a window. This, | |
75 | too, only holds true for classes that do not display a native GTK widget | |
76 | as above. | |
77 | ||
78 | 4) Provide the entire mechanism for scrolling widgets. This actual inter- | |
79 | face for this is usually in wxScrolledWindow, but the GTK implementation | |
80 | is in this class. | |
81 | ||
82 | 5) A multitude of helper or extra methods for special purposes, such as | |
83 | Drag'n'Drop, managing validators etc. | |
84 | ||
85 | Normally one might expect, that one wxWindows window would always correspond | |
86 | to one GTK widget. Under GTK, there is no such allround widget that has all | |
87 | the functionality. Moreover, the GTK defines a client area as a different | |
88 | widget from the actual widget you are handling. Last but not least some | |
89 | special classes (e.g. wxFrame) handle different categories of widgets and | |
90 | still have the possibility to draw something in the client area. | |
91 | It was therefore required to write a special purpose GTK widget, that would | |
92 | represent a client area in the sense of wxWindows capable to do the jobs | |
93 | 2), 3) and 4). I have written this class and it resides in win_gtk.c of | |
94 | this directory. | |
95 | ||
96 | All windows must have a widget, with which they interact with other under- | |
97 | lying GTK widgets. It is this widget, e.g. that has to be resized etc and | |
98 | thw wxWindow class has a member variable called m_widget which holds a | |
99 | pointer to this widget. When the window class represents a GTK native widget, | |
100 | this is (in most cases) the only GTK widget the class manages. E.g. the | |
101 | wxStatitText class handles only a GtkLabel widget a pointer to which you | |
102 | can find in m_widget (defined in wxWindow) | |
103 | ||
104 | When the class has a client area for drawing into and for containing children | |
105 | it has to handle the client area widget (of the type GtkMyFixed, defined in | |
106 | win_gtk.c), but there could be any number of widgets, handled by a class | |
107 | The common rule for all windows is only, that the widget that interacts with | |
108 | the rest of GTK must be referenced in m_widget and all other widgets must be | |
109 | children of this widget on the GTK level. The top-most widget, which also | |
110 | represents the client area, must be in the m_wxwindow field and must be of | |
111 | the type GtkMyFixed. | |
112 | ||
113 | As I said, the window classes that display a GTK native widget only have | |
114 | one widget, so in the case of e.g. the wxButton class m_widget holds a | |
115 | pointer to a GtkButton widget. But windows with client areas (for drawing | |
116 | and children) have a m_widget field that is a pointer to a GtkScrolled- | |
117 | Window and a m_wxwindow field that is pointer to a GtkMyFixed and this | |
118 | one is (in the GTK sense) a child of the GtkScrolledWindow. | |
119 | ||
120 | If the m_wxwindow field is set, then all input to this widget is inter- | |
121 | cepted and sent to the wxWindows class. If not, all input to the widget | |
122 | that gets pointed to by m_widget gets intercepted and sent to the class. | |

2179 | it will then call XXX_size_allocate of its child, which | |
2180 | is m_wxwindow. m_wxwindow in turn will do the same with its | |

2182 | before all the children have been realized as some widgets | |
2183 | stupidy need to be realized during XXX_size_allocate (e.g. | |
2184 | GtkNotebook) and they will segv if called otherwise. this | |
