+   the GTK port of wxWidgets, 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
    for all other window classes, does seems required as well.

+   Normally one might expect, that one wxWidgets window would always correspond
    to 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
    widget from the actual widget you are handling. Last but not least some
    special classes (e.g. wxFrame) handle different categories of widgets and
    still have the possibility to draw something in the client area.
    It was therefore required to write a special purpose GTK widget, that would
-   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.
 
    thw wxWindow class has a member variable called m_widget which holds a
    pointer to this widget. When the window class represents a GTK native widget,
    this is (in most cases) the only GTK widget the class manages. E.g. the
-   wxStatitText class handles only a GtkLabel widget a pointer to which you
+   wxStaticText class handles only a GtkLabel widget a pointer to which you
    can find in m_widget (defined in wxWindow)
 
    When the class has a client area for drawing into and for containing children
    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
+   cepted and sent to the wxWidgets class. If not, all input to the widget
    that gets pointed to by m_widget gets intercepted and sent to the class.

+   The design of scrolling in wxWidgets is markedly different from that offered
    by the GTK itself and therefore we cannot simply take it as it is. In GTK,
    clicking on a scrollbar belonging to scrolled window will inevitably move
-   the window. In wxWindows, the scrollbar will only emit an event, send this
+   the window. In wxWidgets, the scrollbar will only emit an event, send this
    to (normally) a wxScrolledWindow and that class will call ScrollWindow()
    which actually moves the window and its subchildren. Note that GtkPizza
-   memorizes how much it has been scrolled but that wxWindows forgets this
+   memorizes how much it has been scrolled but that wxWidgets forgets this
    so that the two coordinates systems have to be kept in synch. This is done
    in various places using the pizza->xoffset and pizza->yoffset values.
