42/*
43 I have been asked several times about writing some documentation about
44 the GTK port of wxWindows, especially its internal structures. Obviously,
45 you cannot understand wxGTK without knowing a little about the GTK, but
46 some more information about what the wxWindow, which is the base class
47 for all other window classes, does seems required as well.
48
49 What does wxWindow do? It contains the common interface for the following
50 jobs of its descentants:
51
52 1) Define the rudimentary behaviour common to all window classes, such as
53 resizing, intercepting user input so as to make it possible to use these
54 events for special purposes in a derived class, window names etc.
55
56 2) Provide the possibility to contain and manage children, if the derived
57 class is allowed to contain children, which holds true for those window
58 classes, which do not display a native GTK widget. To name them, these
59 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
60 work classes are a special case and are handled a bit differently from
61 the rest.
62
63 3) Provide the possibility to draw into a client area of a window. This,
64 too, only holds true for classes that do not display a native GTK widget
65 as above.
66
67 4) Provide the entire mechanism for scrolling widgets. This actaul inter-
68 face for this is usually in wxScrolledWidget, but the GTK implementation
69 is in this class.
70
71 5) A multitude of helper or extra methods for special purposes, such as
72 Drag'n'Drop, managing validators etc.
73
74 Normally one might expect, that one wxWindows class would always contain
75 one GTK widget. Under GTK, there is no such allround widget that has all
76 the functionality. Moreover, the GTK defines a client area as a different
77 widget from the actual widget you are handling. Last but not least some
78 special classes (e.g. wxFrame) handle different categories of widgets and
79 still have the possibility to draw something in the client area.
80 It was therefore required to write a special purpose GTK widget, that would
81 represent a client area in the sense of wxWindows capable to do the jobs
82 2), 3) and 4). I have written this class and it resides in win_gtk.c of
83 this directory.
84
85 All windows must have a widget, with which they interact with other under-
86 lying GTK widget. It is this widget, e.g. that has to be resized etc and
87 thw wxWindow class has a member variable called m_widget which holds a
88 pointer to this widget. When the window class displays a GTK native widget,
89 this is the only GTK widget the class manages. When the class has a client
90 area for drawing into and for containing children it must have at least
91 one more GTK widget to handle (of the type GtkMyFixed, defined in win_gtk.c),
92 but there can be any number of widgets, handled by a class (e.g. the frame
93 class handles three). The common rule for all windows is only, that the
94 widget that interacts with the rest of GTK must be referenced in m_widget
95 and all other widgets must be children of this widget on the GTK level.
96 The top-most widget, which also represents the client area, must be in
97 the m_wxwindow field and must be of the type GtkMyFixed.
98
99 As I said, the window classes that display a GTK native widget only have
100 one widget, so in the case of e.g. the wxButton class m_widget holds a
101 pointer to a GtkButton widget. But windows with client areas (for drawing
102 and children) have a m_widget field that is a pointer to a GtkScrolled-
103 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
104 one is (in the GTK sense) a child of the GtkScrolledWindow.
105
106 If the m_wxwindow field is set, then all input to this widget is inter-
107 cepted and sent to the wxWindows class. If not, all input to the widget
108 that gets pointed to by m_widget gets intercepted and sent to the class.
