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.

2175 automatically propagate its size down to its m_wxwindow,
2176 which is its client area. therefore, we have to tell the
2177 client area directly that it has to resize itself.
2178 this will lead to that m_widget (GtkScrolledWindow) will
2179 calculate how much size it needs for scrollbars etc and
2180 it will then call XXX_size_allocate of its child, which
2181 is m_wxwindow. m_wxwindow in turn will do the same with its
2182 children and so on. problems can arise if this happens
2183 before all the children have been realized as some widgets
2184 stupidy need to be realized during XXX_size_allocate (e.g.
2185 GtkNotebook) and they will segv if called otherwise. this
2186 emergency is tested in gtk_myfixed_size_allocate. Normally
2187 this shouldn't be needed and only gtk_widget_queue_resize()
2188 should be enough to provoke a resize at the next appropriate
2189 moment, but this seems to fail, e.g. when a wxNotebook contains
2190 a wxSplitterWindow: the splitter window's children won't
2191 show up properly resized then. */
