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.  

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

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.

See also QSizePolicy::ExpandData.

Reimplemented from QLayoutItem.  

bool QSpacerItem::isEmpty () const [virtual]

Returns TRUE because a spacer item never contains widgets.

Reimplemented from QLayoutItem.  

QSize QSpacerItem::maximumSize () const [virtual]

Returns the maximum size of this spacer item.

Reimplemented from QLayoutItem.  

QSize QSpacerItem::minimumSize () const [virtual]

Returns the minimum size of this spacer item.

Reimplemented from QLayoutItem.  

void QSpacerItem::setGeometry ( const QRect & r ) [virtual]

Stores the spacer item's rect r so that it can be returned by geometry().

Reimplemented from QLayoutItem.  

QSize QSpacerItem::sizeHint () const [virtual]

Returns the preferred size of this spacer item.
