<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>
<p><table align="center" border="0" cellpadding="2" cellspacing="1" class="generic">
<thead><tr class="qt-style" valign="top"><th>Class</th><th>Functions</th></tr></thead>
<tr class="odd" valign="top"><td><a href="qhboxlayout.html">QHBoxLayout</a></td><td><a href="qboxlayout.html#addSpacing">addSpacing()</a>, <a href="qboxlayout.html#addStretch">addStretch()</a>, <a href="qboxlayout.html#insertSpacing">insertSpacing()</a>, <a href="qboxlayout.html#insertStretch">insertStretch()</a></td></tr>
<tr class="even" valign="top"><td><a href="qgridlayout.html">QGridLayout</a></td><td><a href="qgridlayout.html#setRowMinimumHeight">setRowMinimumHeight()</a>, <a href="qgridlayout.html#setRowStretch">setRowStretch()</a>, <a href="qgridlayout.html#setColumnMinimumWidth">setColumnMinimumWidth()</a>, <a href="qgridlayout.html#setColumnStretch">setColumnStretch()</a></td></tr>

<p>The default values provide a gap that is able to stretch if nothing else wants the space.</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>
