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

1995 automatically propagate its size down to its m_wxwindow,
1996 which is its client area. therefore, we have to tell the
1997 client area directly that it has to resize itself.
1998 this will lead to that m_widget (GtkScrolledWindow) will
1999 calculate how much size it needs for scrollbars etc and
2000 it will then call XXX_size_allocate of its child, which
2001 is m_wxwindow. m_wxwindow in turn will do the same with its
2002 children and so on. problems can arise if this happens
2003 before all the children have been realized as some widgets
2004 stupidy need to be realized during XXX_size_allocate (e.g.
2005 GtkNotebook) and they will segv if called otherwise. this
2006 emergency is tested in gtk_myfixed_size_allocate. Normally
2007 this shouldn't be needed and only gtk_widget_queue_resize()
2008 should be enough to provoke a resize at the next appropriate
2009 moment, but this seems to fail, e.g. when a wxNotebook contains
