46/*
47 I have been asked several times about writing some documentation about
48 the GTK port of wxWindows, especially its internal structures. Obviously,
49 you cannot understand wxGTK without knowing a little about the GTK, but
50 some more information about what the wxWindow, which is the base class
51 for all other window classes, does seems required as well.
52
53 What does wxWindow do? It contains the common interface for the following
54 jobs of its descendants:
55
56 1) Define the rudimentary behaviour common to all window classes, such as
57 resizing, intercepting user input (so as to make it possible to use these
58 events for special purposes in a derived class), window names etc.
59
60 2) Provide the possibility to contain and manage children, if the derived
61 class is allowed to contain children, which holds true for those window
62 classes which do not display a native GTK widget. To name them, these
63 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
64 work classes are a special case and are handled a bit differently from
65 the rest. The same holds true for the wxNotebook class.
66
67 3) Provide the possibility to draw into a client area of a window. This,
68 too, only holds true for classes that do not display a native GTK widget
69 as above.
70
71 4) Provide the entire mechanism for scrolling widgets. This actual inter-
72 face for this is usually in wxScrolledWindow, but the GTK implementation
73 is in this class.
74
75 5) A multitude of helper or extra methods for special purposes, such as
76 Drag'n'Drop, managing validators etc.
77
78 Normally one might expect, that one wxWindows window would always correspond
79 to one GTK widget. Under GTK, there is no such allround widget that has all
80 the functionality. Moreover, the GTK defines a client area as a different
81 widget from the actual widget you are handling. Last but not least some
82 special classes (e.g. wxFrame) handle different categories of widgets and
83 still have the possibility to draw something in the client area.
84 It was therefore required to write a special purpose GTK widget, that would
85 represent a client area in the sense of wxWindows capable to do the jobs
86 2), 3) and 4). I have written this class and it resides in win_gtk.c of
87 this directory.
88
89 All windows must have a widget, with which they interact with other under-
90 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
91 thw wxWindow class has a member variable called m_widget which holds a
92 pointer to this widget. When the window class represents a GTK native widget,
93 this is (in most cases) the only GTK widget the class manages. E.g. the
94 wxStatitText class handles only a GtkLabel widget a pointer to which you
95 can find in m_widget (defined in wxWindow)
96
97 When the class has a client area for drawing into and for containing children
98 it has to handle the client area widget (of the type GtkMyFixed, defined in
99 win_gtk.c), but there could be any number of widgets, handled by a class
100 The common rule for all windows is only, that the widget that interacts with
101 the rest of GTK must be referenced in m_widget and all other widgets must be
102 children of this widget on the GTK level. The top-most widget, which also
103 represents the client area, must be in the m_wxwindow field and must be of
104 the type GtkMyFixed.
105
106 As I said, the window classes that display a GTK native widget only have
107 one widget, so in the case of e.g. the wxButton class m_widget holds a
108 pointer to a GtkButton widget. But windows with client areas (for drawing
109 and children) have a m_widget field that is a pointer to a GtkScrolled-
110 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
111 one is (in the GTK sense) a child of the GtkScrolledWindow.
112
113 If the m_wxwindow field is set, then all input to this widget is inter-
114 cepted and sent to the wxWindows class. If not, all input to the widget
115 that gets pointed to by m_widget gets intercepted and sent to the class.
