50 \brief The Q3Grid widget provides simple geometry management of its children. |
|
51 |
|
52 \compat |
|
53 |
|
54 The grid places its widgets either in columns or in rows depending |
|
55 on its orientation. |
|
56 |
|
57 The number of rows \e or columns is defined in the constructor. |
|
58 All the grid's children will be placed and sized in accordance |
|
59 with their sizeHint() and sizePolicy(). |
|
60 |
|
61 Use setMargin() to add space around the grid itself, and |
|
62 setSpacing() to add space between the widgets. |
