Member Function Documentation
TQSpacerItem::TQSpacerItem ( int w, int h, TQSizePolicy::SizeType hData = TQSizePolicy::Minimum, TQSizePolicy::SizeType vData = TQSizePolicy::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 TQSpacerItem::changeSize ( int w, int h, TQSizePolicy::SizeType hData = TQSizePolicy::Minimum, TQSizePolicy::SizeType vData = TQSizePolicy::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.
Returns the direction in which this spacer item will expand.
See also TQSizePolicy::ExpandData.
Reimplemented from TQLayoutItem.
bool TQSpacerItem::isEmpty () const [virtual]
Returns TRUE because a spacer item never contains widgets.
Reimplemented from TQLayoutItem.
TQSize TQSpacerItem::maximumSize () const [virtual]
Returns the maximum size of this spacer item.
Reimplemented from TQLayoutItem.
TQSize TQSpacerItem::minimumSize () const [virtual]
Returns the minimum size of this spacer item.
Reimplemented from TQLayoutItem.
void TQSpacerItem::setGeometry ( const TQRect & r ) [virtual]
Stores the spacer item's rect r so that it can be returned by
geometry().
Reimplemented from TQLayoutItem.
TQSize TQSpacerItem::sizeHint () const [virtual]
Returns the preferred size of this spacer item.
