## 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.

### TQSizePolicy::ExpandData TQSpacerItem::expanding () const`[virtual]`

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.

Reimplemented from TQLayoutItem.
