40 /*
41 I have been asked several times about writing some documentation about
42 the GTK port of wxWindows, especially its internal structures. Obviously,
43 you cannot understand wxGTK without knowing a little about the GTK, but
44 some more information about what the wxWindow, which is the base class
45 for all other window classes, does seems required as well.
46
47 What does wxWindow do? It contains the common interface for the following
48 jobs of its descendants:
49
50 1) Define the rudimentary behaviour common to all window classes, such as
51 resizing, intercepting user input (so as to make it possible to use these
52 events for special purposes in a derived class), window names etc.
53
54 2) Provide the possibility to contain and manage children, if the derived
55 class is allowed to contain children, which holds true for those window
56 classes which do not display a native GTK widget. To name them, these
57 classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
58 work classes are a special case and are handled a bit differently from
59 the rest. The same holds true for the wxNotebook class.
60
61 3) Provide the possibility to draw into a client area of a window. This,
62 too, only holds true for classes that do not display a native GTK widget
63 as above.
64
65 4) Provide the entire mechanism for scrolling widgets. This actual inter-
66 face for this is usually in wxScrolledWindow, but the GTK implementation
67 is in this class.
68
69 5) A multitude of helper or extra methods for special purposes, such as
70 Drag'n'Drop, managing validators etc.
71
72 Normally one might expect, that one wxWindows window would always correspond
73 to one GTK widget. Under GTK, there is no such allround widget that has all
74 the functionality. Moreover, the GTK defines a client area as a different
75 widget from the actual widget you are handling. Last but not least some
76 special classes (e.g. wxFrame) handle different categories of widgets and
77 still have the possibility to draw something in the client area.
78 It was therefore required to write a special purpose GTK widget, that would
79 represent a client area in the sense of wxWindows capable to do the jobs
80 2), 3) and 4). I have written this class and it resides in win_gtk.c of
81 this directory.
82
83 All windows must have a widget, with which they interact with other under-
84 lying GTK widgets. It is this widget, e.g. that has to be resized etc and
85 thw wxWindow class has a member variable called m_widget which holds a
86 pointer to this widget. When the window class represents a GTK native widget,
87 this is (in most cases) the only GTK widget the class manages. E.g. the
88 wxStatitText class handles only a GtkLabel widget a pointer to which you
89 can find in m_widget (defined in wxWindow)
90
91 When the class has a client area for drawing into and for containing children
92 it has to handle the client area widget (of the type GtkMyFixed, defined in
93 win_gtk.c), but there could be any number of widgets, handled by a class
94 The common rule for all windows is only, that the widget that interacts with
95 the rest of GTK must be referenced in m_widget and all other widgets must be
96 children of this widget on the GTK level. The top-most widget, which also
97 represents the client area, must be in the m_wxwindow field and must be of
98 the type GtkMyFixed.
99
100 As I said, the window classes that display a GTK native widget only have
101 one widget, so in the case of e.g. the wxButton class m_widget holds a
102 pointer to a GtkButton widget. But windows with client areas (for drawing
103 and children) have a m_widget field that is a pointer to a GtkScrolled-
104 Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
105 one is (in the GTK sense) a child of the GtkScrolledWindow.
106
107 If the m_wxwindow field is set, then all input to this widget is inter-
108 cepted and sent to the wxWindows class. If not, all input to the widget
109 that gets pointed to by m_widget gets intercepted and sent to the class.
