45/*
46 I have been asked several times about writing some documentation about
47 the GTK port of wxWindows, especially its internal structures. Obviously,
48 you cannot understand wxGTK without knowing a little about the GTK, but
47d67540 49 some more information about what the wxWindow, which is the base class
868a2826 50 for all other window classes, does seems required as well.
47d67540 51
868a2826 52 What does wxWindow do? It contains the common interface for the following
e380f72b 53 jobs of its descendants:
47d67540 54
868a2826 55 1) Define the rudimentary behaviour common to all window classes, such as
e380f72b
RR		 56 resizing, intercepting user input (so as to make it possible to use these
57 events for special purposes in a derived class), window names etc.
868a2826
RR		 58
59 2) Provide the possibility to contain and manage children, if the derived
60 class is allowed to contain children, which holds true for those window
e380f72b 61 classes which do not display a native GTK widget. To name them, these
868a2826 62 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
47d67540 63 work classes are a special case and are handled a bit differently from
e380f72b 64 the rest. The same holds true for the wxNotebook class.
47d67540 65
868a2826
RR		 66 3) Provide the possibility to draw into a client area of a window. This,
67 too, only holds true for classes that do not display a native GTK widget
68 as above.
47d67540 69
e380f72b
RR		 70 4) Provide the entire mechanism for scrolling widgets. This actual inter-
71 face for this is usually in wxScrolledWindow, but the GTK implementation
868a2826 72 is in this class.
47d67540 73
868a2826
RR		 74 5) A multitude of helper or extra methods for special purposes, such as
75 Drag'n'Drop, managing validators etc.
47d67540 76
e380f72b
RR		 77 Normally one might expect, that one wxWindows window would always correspond
78 to one GTK widget. Under GTK, there is no such allround widget that has all
868a2826
RR		 79 the functionality. Moreover, the GTK defines a client area as a different
80 widget from the actual widget you are handling. Last but not least some
81 special classes (e.g. wxFrame) handle different categories of widgets and
82 still have the possibility to draw something in the client area.
83 It was therefore required to write a special purpose GTK widget, that would
84 represent a client area in the sense of wxWindows capable to do the jobs
85 2), 3) and 4). I have written this class and it resides in win_gtk.c of
86 this directory.
47d67540 87
868a2826 88 All windows must have a widget, with which they interact with other under-
e380f72b 89 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
868a2826 90 thw wxWindow class has a member variable called m_widget which holds a
e380f72b
RR		 91 pointer to this widget. When the window class represents a GTK native widget,
92 this is (in most cases) the only GTK widget the class manages. E.g. the
93 wxStatitText class handles only a GtkLabel widget a pointer to which you
94 can find in m_widget (defined in wxWindow)
8bbe427f 95
e380f72b 96 When the class has a client area for drawing into and for containing children
8bbe427f
VZ		 97 it has to handle the client area widget (of the type GtkMyFixed, defined in
98 win_gtk.c), but there could be any number of widgets, handled by a class
99 The common rule for all windows is only, that the widget that interacts with
100 the rest of GTK must be referenced in m_widget and all other widgets must be
101 children of this widget on the GTK level. The top-most widget, which also
102 represents the client area, must be in the m_wxwindow field and must be of
e380f72b 103 the type GtkMyFixed.
47d67540 104
868a2826
RR		 105 As I said, the window classes that display a GTK native widget only have
106 one widget, so in the case of e.g. the wxButton class m_widget holds a
107 pointer to a GtkButton widget. But windows with client areas (for drawing
108 and children) have a m_widget field that is a pointer to a GtkScrolled-
109 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
110 one is (in the GTK sense) a child of the GtkScrolledWindow.
47d67540 111
868a2826
RR		 112 If the m_wxwindow field is set, then all input to this widget is inter-
113 cepted and sent to the wxWindows class. If not, all input to the widget
114 that gets pointed to by m_widget gets intercepted and sent to the class.
