<p>Normally, you don't need to use this class directly. Qt's
built-in layout managers provide the following functions for
manipulating empty space in layouts:</p>

preferred height <i>h</i>, horizontal size policy <i>hPolicy</i>
and vertical size policy <i>vPolicy</i>.</p>
<p>The default values provide a gap that is able to stretch if
nothing else wants the space.</p>
<h3 class="fn"><a name="QSpacerItem-2" />QSpacerItem.__init__ (<i>self</i>, <a href="qspaceritem.html">QSpacerItem</a>)</h3><h3 class="fn"><a name="changeSize" />QSpacerItem.changeSize (<i>self</i>, int <i>w</i>, int <i>h</i>, <a href="qsizepolicy.html#Policy-enum">QSizePolicy.Policy</a> <i>hPolicy</i> = QSizePolicy.Minimum, <a href="qsizepolicy.html#Policy-enum">QSizePolicy.Policy</a> <i>vPolicy</i> = QSizePolicy.Minimum)</h3><p>Changes this spacer item to have preferred width <i>w</i>,
preferred height <i>h</i>, horizontal size policy <i>hPolicy</i>
and vertical size policy <i>vPolicy</i>.</p>
<p>The default values provide a gap that is able to stretch if
nothing else wants the space.</p>
<p>Note that if changeSize() is called after the spacer item has
been added to a layout, it is necessary to invalidate the layout in
order for the spacer item's new size to take effect.</p>
