<hr><h2><a name="details"></a>Detailed Description</h2>
The QSize class defines the size of a two-dimensional object.
<p>
A size is specified by a width and a height.
<p>The coordinate type is QCOORD (defined in <a href="qwindowdefs-h.html">qwindowdefs.h</a> as <code>int).</code>
The minimum value of QCOORD is QCOORD_MIN (-2147483648) and the maximum
value is  QCOORD_MAX (2147483647).
<p>See also  <a href="qpoint.html">QPoint</a> and <a href="qrect.html">QRect</a>.

<h3 class="fn">QSize<a name="4b5734"></a>QSize::boundedTo(constQSize&amp;otherSize)const</h3>
<p>Returns a size with the minimum width and height of this size and
<em>otherSize.</em>
<h3 class="fn">QSize<a name="a74829"></a>QSize::expandedTo(constQSize&amp;otherSize)const</h3>
<p>Returns a size with the maximum width and height of this size and
<em>otherSize.</em>
<h3 class="fn">int<a name="a35c26"></a>QSize::height()const</h3>
<p>Returns the height.
<p>See also  <a href="#37cddf">width</a>().
<p>Examples:
 <a href="qfd-qfd-cpp.html#height">qfd/qfd.cpp</a>
<h3 class="fn">bool<a name="8596f2"></a>QSize::isEmpty()const</h3>
<p>Returns TRUE if the width is <= 0 or the height is <= 0,
otherwise FALSE.
<h3 class="fn">bool<a name="ac49ee"></a>QSize::isNull()const</h3>
<p>Returns TRUE if the width is 0 and the height is 0, otherwise FALSE.
<h3 class="fn">bool<a name="7336d9"></a>QSize::isValid()const</h3>
<p>Returns TRUE if the width is equal to or greater than 0 and the height is
equal to or greater than 0, otherwise FALSE.
<h3 class="fn">QSize&amp;<a name="2db5ca"></a>QSize::operator*=(doublec)</h3>
<p>Multiplies both the width and height with <em>c</em> and returns a reference to
the size.
<p>Note that the result is truncated.
<h3 class="fn">QSize&amp;<a name="cbc534"></a>QSize::operator*=(intc)</h3>
<p>Multiplies both the width and height with <em>c</em> and returns a reference to
the size.
<h3 class="fn">QSize&amp;<a name="14aea3"></a>QSize::operator+=(constQSize&amp;s)</h3>
<p>Adds <em>s</em> to the size and returns a reference to this size.
<p>Example:
<pre>    <a href="qsize.html">QSize</a> s(  3, 7 );
    <a href="qsize.html">QSize</a> r( -1, 4 );
    s += r;                     // s becomes (2,11)
</pre>
<h3 class="fn">QSize&amp;<a name="9b556a"></a>QSize::operator-=(constQSize&amp;s)</h3>
<p>Subtracts <em>s</em> from the size and returns a reference to this size.
<p>Example:
<pre>    <a href="qsize.html">QSize</a> s(  3, 7 );
    <a href="qsize.html">QSize</a> r( -1, 4 );
    s -= r;                     // s becomes (4,3)
</pre>
<h3 class="fn">QSize&amp;<a name="af8132"></a>QSize::operator/=(doublec)</h3>

size.
<h3 class="fn">QCOORD&amp;<a name="457d54"></a>QSize::rheight()</h3>
<p>Returns a reference to the height.
<p>Using a reference makes it possible to directly manipulate the height.
<p>Example:
<pre>    <a href="qsize.html">QSize</a> s( 100, 10 );
    s.<a href="#457d54">rheight</a>() += 5;           // s becomes (100,15)
