\class QGridView qgridview.h
\brief The QGridView 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 content 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, 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).
QGridView is a very simple abstract class based on QScrollView. 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 in different sizes, use a QTable instead. If you need a
simple list of items, use a QListBox. If you need to present
hierachical data use a QListView, and if you need random objects at
random positions, consider using either a QIconView or a QCanvas.
