\class Q3Grid | |
\brief The Q3Grid widget provides simple geometry management of its children. | |
\compat | |
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. | |
