\brief The QGrid widget provides simple geometry management of its children.
\ingroup geomanagement
\ingroup appearance
The grid places its widgets either in columns or in rows depending
on its orientation.
The number of rows \e or columns is defined in the constructor.
All the grid's children will be placed and sized in accordance
with their sizeHint() and sizePolicy().
Use setMargin() to add space around the grid itself, and
setSpacing() to add space between the widgets.
