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