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 gives 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 gives a gap that is able to stretch,
if nothing else wants the space.
Returns whether this space item is expanding.
Reimplemented from QLayoutItem.
bool QSpacerItem::isEmpty () const [virtual]
Returns TRUE, since a space item never contains widgets.
Reimplemented from QLayoutItem.
QSize QSpacerItem::maximumSize () const [virtual]
Returns the maximum size of this space item.
Reimplemented from QLayoutItem.
QSize QSpacerItem::minimumSize () const [virtual]
Returns the minimum size of this space item.
Reimplemented from QLayoutItem.
void QSpacerItem::setGeometry ( const QRect & r ) [virtual]
This function stores r, so it can be returned by geometry().
Reimplemented from QLayoutItem.
QSize QSpacerItem::sizeHint () const [virtual]
Returns the preferred size of this space item.
Reimplemented from QLayoutItem.
