41 /*
42 I have been asked several times about writing some documentation about
43 the GTK port of wxWindows, especially its internal structures. Obviously,
44 you cannot understand wxGTK without knowing a little about the GTK, but
45 some more information about what the wxWindow, which is the base class
46 for all other window classes, does seems required as well.
47
48 What does wxWindow do? It contains the common interface for the following
49 jobs of its descentants:
50
51 1) Define the rudimentary behaviour common to all window classes, such as
52 resizing, intercepting user input so as to make it possible to use these
53 events for special purposes in a derived class, window names etc.
54
55 2) Provide the possibility to contain and manage children, if the derived
56 class is allowed to contain children, which holds true for those window
57 classes, which do not display a native GTK widget. To name them, these
58 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
59 work classes are a special case and are handled a bit differently from
60 the rest.
61
62 3) Provide the possibility to draw into a client area of a window. This,
63 too, only holds true for classes that do not display a native GTK widget
64 as above.
65
66 4) Provide the entire mechanism for scrolling widgets. This actaul inter-
67 face for this is usually in wxScrolledWidget, but the GTK implementation
68 is in this class.
69
70 5) A multitude of helper or extra methods for special purposes, such as
71 Drag'n'Drop, managing validators etc.
72
73 Normally one might expect, that one wxWindows class would always contain
74 one GTK widget. Under GTK, there is no such allround widget that has all
75 the functionality. Moreover, the GTK defines a client area as a different
76 widget from the actual widget you are handling. Last but not least some
77 special classes (e.g. wxFrame) handle different categories of widgets and
78 still have the possibility to draw something in the client area.
79 It was therefore required to write a special purpose GTK widget, that would
80 represent a client area in the sense of wxWindows capable to do the jobs
81 2), 3) and 4). I have written this class and it resides in win_gtk.c of
82 this directory.
83
84 All windows must have a widget, with which they interact with other under-
85 lying GTK widget. It is this widget, e.g. that has to be resized etc and
86 thw wxWindow class has a member variable called m_widget which holds a
87 pointer to this widget. When the window class displays a GTK native widget,
88 this is the only GTK widget the class manages. When the class has a client
89 area for drawing into and for containing children it must have at least
90 one more GTK widget to handle (of the type GtkMyFixed, defined in win_gtk.c),
91 but there can be any number of widgets, handled by a class (e.g. the frame
92 class handles three). The common rule for all windows is only, that the
93 widget that interacts with the rest of GTK must be referenced in m_widget
94 and all other widgets must be children of this widget on the GTK level.
95 The top-most widget, which also represents the client area, must be in
96 the m_wxwindow field and must be of the type GtkMyFixed.
97
98 As I said, the window classes that display a GTK native widget only have
99 one widget, so in the case of e.g. the wxButton class m_widget holds a
100 pointer to a GtkButton widget. But windows with client areas (for drawing
101 and children) have a m_widget field that is a pointer to a GtkScrolled-
102 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
103 one is (in the GTK sense) a child of the GtkScrolledWindow.
104
105 If the m_wxwindow field is set, then all input to this widget is inter-
106 cepted and sent to the wxWindows class. If not, all input to the widget
107 that gets pointed to by m_widget gets intercepted and sent to the class.
