Implemented in subclasses to add an item.
How it is added is specific to each subclass.
This function is not usually called in application code. To add a widget to a layout, use the addWidget() function; to add a child layout, use the addLayout() function provided by the relevant QLayout subclass.
{Note:} The ownership of item is transferred to the layout, and it's the layout's responsibility to delete it.

Returns whether this layout can make use of more space than sizeHint().
A value of Qt::Vertical or Qt::Horizontal means that it wants to grow in only one dimension, whereas Qt::Vertical | Qt::Horizontal means that it wants to grow in both dimensions.
The default implementation returns Qt::Horizontal | Qt::Vertical. Subclasses reimplement it to return a meaningful value based on their child widgets's \l{QSizePolicy}{size policies}.
