// documentation on internals
I have been asked several times about writing some documentation about
the GTK port of wxWindows, especially its internal structures. Obviously,
you cannot understand wxGTK without knowing a little about the GTK, but
- some more information about what the wxWindow, which is the base class
+ some more information about what the wxWindow, which is the base class
for all other window classes, does seems required as well.
-
+
What does wxWindow do? It contains the common interface for the following
jobs of its descentants:
-
+
1) Define the rudimentary behaviour common to all window classes, such as
resizing, intercepting user input so as to make it possible to use these
events for special purposes in a derived class, window names etc.
class is allowed to contain children, which holds true for those window
classes, which do not display a native GTK widget. To name them, these
classes are wxPanel, wxScrolledWindow, wxDialog, wxFrame. The MDI frame-
- work classes are a special case and are handled a bit differently from
+ work classes are a special case and are handled a bit differently from
the rest.
-
+
3) Provide the possibility to draw into a client area of a window. This,
too, only holds true for classes that do not display a native GTK widget
as above.
-
+
4) Provide the entire mechanism for scrolling widgets. This actaul inter-
face for this is usually in wxScrolledWidget, but the GTK implementation
is in this class.
-
+
5) A multitude of helper or extra methods for special purposes, such as
Drag'n'Drop, managing validators etc.
-
+
Normally one might expect, that one wxWindows class would always contain
one GTK widget. Under GTK, there is no such allround widget that has all
the functionality. Moreover, the GTK defines a client area as a different
represent a client area in the sense of wxWindows capable to do the jobs
2), 3) and 4). I have written this class and it resides in win_gtk.c of
this directory.
-
+
All windows must have a widget, with which they interact with other under-
lying GTK widget. It is this widget, e.g. that has to be resized etc and
thw wxWindow class has a member variable called m_widget which holds a
and all other widgets must be children of this widget on the GTK level.
The top-most widget, which also represents the client area, must be in
the m_wxwindow field and must be of the type GtkMyFixed.
-
+
As I said, the window classes that display a GTK native widget only have
one widget, so in the case of e.g. the wxButton class m_widget holds a
pointer to a GtkButton widget. But windows with client areas (for drawing
and children) have a m_widget field that is a pointer to a GtkScrolled-
Window and a m_wxwindow field that is pointer to a GtkMyFixed and this
one is (in the GTK sense) a child of the GtkScrolledWindow.
-
+
If the m_wxwindow field is set, then all input to this widget is inter-
cepted and sent to the wxWindows class. If not, all input to the widget
that gets pointed to by m_widget gets intercepted and sent to the class.
