<h3 class=fn><a name="QSpacerItem"></a>QSpacerItem::QSpacerItem ( int w, int h, <a href="qsizepolicy.html#SizeType-enum">QSizePolicy::SizeType</a> hData = QSizePolicy::Minimum, <a href="qsizepolicy.html#SizeType-enum">QSizePolicy::SizeType</a> vData = QSizePolicy::Minimum )
</h3>
<p> Constructs a spacer item with preferred width <em>w</em>, preferred height
<em>h</em>, horizontal size policy <em>hData</em> and vertical size policy
<em>vData</em>.
<p> The default values provide a gap that is able to stretch
if nothing else wants the space.
<h3 class=fn>void <a name="changeSize"></a>QSpacerItem::changeSize ( int w, int h, <a href="qsizepolicy.html#SizeType-enum">QSizePolicy::SizeType</a> hData = QSizePolicy::Minimum, <a href="qsizepolicy.html#SizeType-enum">QSizePolicy::SizeType</a> vData = QSizePolicy::Minimum )
</h3>
Changes this spacer item to have preferred width <em>w</em>, preferred height
<em>h</em>, horizontal size policy <em>hData</em> and vertical size policy
<em>vData</em>.
<p> The default values provide a gap that is able to stretch
if nothing else wants the space.
<h3 class=fn><a href="qsizepolicy.html#ExpandData-enum">QSizePolicy::ExpandData</a> <a name="expanding"></a>QSpacerItem::expanding () const<tt> [virtual]</tt>
</h3>
Returns TRUE if this spacer item is expanding; otherwise returns FALSE.
<p>Reimplemented from <a href="qlayoutitem.html#expanding">QLayoutItem</a>.
<h3 class=fn>bool <a name="isEmpty"></a>QSpacerItem::isEmpty () const<tt> [virtual]</tt>
</h3>
Returns TRUE because a spacer item never contains widgets.
<p>Reimplemented from <a href="qlayoutitem.html#isEmpty">QLayoutItem</a>.
<h3 class=fn><a href="qsize.html">QSize</a> <a name="maximumSize"></a>QSpacerItem::maximumSize () const<tt> [virtual]</tt>
</h3>
Returns the maximum size of this space item.
<p>Reimplemented from <a href="qlayoutitem.html#maximumSize">QLayoutItem</a>.
<h3 class=fn><a href="qsize.html">QSize</a> <a name="minimumSize"></a>QSpacerItem::minimumSize () const<tt> [virtual]</tt>
</h3>
Returns the minimum size of this spacer item.

<h3 class=fn>void <a name="setGeometry"></a>QSpacerItem::setGeometry ( const <a href="qrect.html">QRect</a> & r )<tt> [virtual]</tt>
</h3>
Stores the spacer item's rect <em>r</em> so that it can be returned by
<a href="qlayoutitem.html#geometry">geometry</a>().
<p>Reimplemented from <a href="qlayoutitem.html#setGeometry">QLayoutItem</a>.
<h3 class=fn><a href="qsize.html">QSize</a> <a name="sizeHint"></a>QSpacerItem::sizeHint () const<tt> [virtual]</tt>
