## Detailed Description

The Q3Grid widget provides simple geometry management of its children.

The grid places its widgets either in columns or in rows depending on its orientation.

The number of rows 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.

See also Q3VBox, Q3HBox, and QGridLayout.

## Member Function Documentation

### Q3Grid::Q3Grid ( int n, QWidget * parent = 0, const char * name = 0, Qt::WindowFlags f = 0 )

Constructs a grid widget with parent parent, called name. n specifies the number of columns. The widget flags f are passed to the Q3Frame constructor.

### Q3Grid::Q3Grid ( int n, Qt::Orientation orient, QWidget * parent = 0, const char * name = 0, Qt::WindowFlags f = 0 )

Constructs a grid widget with parent parent, called name. If orient is `Horizontal`, n specifies the number of columns. If orient is `Vertical`, n specifies the number of rows. The widget flags f are passed to the Q3Frame constructor.

### void Q3Grid::frameChanged ()`[virtual protected]`

Reimplemented from Q3Frame::frameChanged().

### void Q3Grid::setSpacing ( int space )

Sets the spacing between the child widgets to space.

### QSize Q3Grid::sizeHint () const`[virtual]`

Reimplemented from QWidget::sizeHint().
