Member Function Documentation

QSpacerItem::QSpacerItem ( int w, int h, QSizePolicy::SizeType hData = QSizePolicy::Minimum, QSizePolicy::SizeType vData = QSizePolicy::Minimum )

Constructs a spacer item with preferred width w, preferred height h, horizontal size policy hData and vertical size policy vData.

The default values provide a gap that is able to stretch if nothing else wants the space.

Changes this spacer item to have preferred width w, preferred height h, horizontal size policy hData and vertical size policy vData.

The default values provide a gap that is able to stretch if nothing else wants the space.

QSizePolicy::ExpandData QSpacerItem::expanding () const [virtual]

Returns the direction in which this spacer item will expand.
