+  \class QtTableView qttableview.h
+  \brief The QtTableView class provides an abstract base for tables.
+
+  \obsolete
+
+  A table view consists of a number of abstract cells organized in rows
+  and columns, and a visible part called a view. The cells are identified
+  with a row index and a column index. The top-left cell is in row 0,
+  column 0.
+
+  The behavior of the widget can be finely tuned using
+  setTableFlags(); a typical subclass will consist of little more than a
+  call to setTableFlags(), some table content manipulation and an
+  implementation of paintCell().  Subclasses that need cells with
+  variable width or height must reimplement cellHeight() and/or
+  cellWidth(). Use updateTableSize() to tell QtTableView when the
+  width or height has changed.
+
+  When you read this documentation, it is important to understand the
+  distinctions among the four pixel coordinate systems involved.
+
+  \list 1
+  \i The \e cell coordinates.  (0,0) is the top-left corner of a cell.
+  Cell coordinates are used by functions such as paintCell().
+
+  \i The \e table coordinates.  (0,0) is the top-left corner of the cell at
+  row 0 and column 0. These coordinates are absolute; that is, they are
+  independent of what part of the table is visible at the moment. They are
+  used by functions such as setXOffset() or maxYOffset().
+
+  \i The \e widget coordinates. (0,0) is the top-left corner of the widget,
+  \e including the frame.  They are used by functions such as repaint().
+
+  \i The \e view coordinates.  (0,0) is the top-left corner of the view, \e
+  excluding the frame.  This is the least-used coordinate system; it is used by
+  functions such as viewWidth().  \endlist
+
+  It is rather unfortunate that we have to use four different
+  coordinate systems, but there was no alternative to provide a flexible and
+  powerful base class.
+
+  Note: The row,column indices are always given in that order,
+  i.e., first the vertical (row), then the horizontal (column). This is
+  the opposite order of all pixel operations, which take first the
+  horizontal (x) and then the vertical (y).
+
+  <img src=qtablevw-m.png> <img src=qtablevw-w.png>
+
+  \warning the functions setNumRows(), setNumCols(), setCellHeight(),
+  setCellWidth(), setTableFlags() and clearTableFlags() may cause
+  virtual functions such as cellWidth() and cellHeight() to be called,
+  even if autoUpdate() is FALSE.  This may cause errors if relevant
+  state variables are not initialized.
+
+  \warning Experience has shown that use of this widget tends to cause
+  more bugs than expected and our analysis indicates that the widget's
+  very flexibility is the problem.  If QScrollView or QListBox can
+  easily be made to do the job you need, we recommend subclassing
+  those widgets rather than QtTableView. In addition, QScrollView makes
+  it easy to have child widgets inside tables, which QtTableView
+  doesn't support at all.
