+    \class TQGridView qgridview.h
+    \brief The TQGridView class provides an abstract base for
+    fixed-size grids.
+
+    \ingroup abstractwidgets
+
+    A grid view consists of a number of abstract cells organized in
+    rows and columns. The cells have a fixed size and are identified
+    with a row index and a column index. The top-left cell is in row
+    0, column 0. The bottom-right cell is in row numRows()-1, column
+    numCols()-1.
+
+    You can define \l numRows, \l numCols, \l cellWidth and \l
+    cellHeight. Reimplement the pure virtual function paintCell() to
+    draw the contents of a cell.
+
+    With ensureCellVisible(), you can ensure a certain cell is
+    visible. With rowAt() and columnAt() you can find a cell based on
+    the given x- and y-coordinates.
+
+    If you need to monitor changes to the grid's dimensions (i.e. when
+    numRows or numCols is changed), reimplement the dimensionChange()
+    change handler.
+
+    Note: the row and column indices are always given in the order,
+    row (vertical offset) then column (horizontal offset). This order
+    is the opposite of all pixel operations, which are given in the
+    order x (horizontal offset), y (vertical offset).
+
+    TQGridView is a very simple abstract class based on TQScrollView. It
+    is designed to simplify the task of drawing many cells of the same
+    size in a potentially scrollable canvas. If you need rows and
+    columns with different sizes, use a TQTable instead. If you need a
+    simple list of items, use a TQListBox. If you need to present
+    hierachical data use a TQListView, and if you need random objects
+    at random positions, consider using either a TQIconView or a
+    TQCanvas.
