<hr><a name="details"></a><h2>Detailed Description</h2>
The TQSize class defines the size of a two-dimensional object.
<p>
<p> A size is specified by a width and a height.
<p> The coordinate type is TQCOORD (defined in <tt><ntqwindowdefs.h></tt> as <tt>int</tt>).
The minimum value of TQCOORD is TQCOORD_MIN (-2147483648) and the maximum
value is TQCOORD_MAX (2147483647).
<p> The size can be set in the constructor and changed with <a href="#setWidth">setWidth</a>()
and <a href="#setHeight">setHeight</a>(), or using <a href="#operator+-eq">operator+=</a>(), <a href="#operator--eq">operator-=</a>(), <a href="#operator*-eq">operator*=</a>()
and <a href="#operator/-eq">operator/=</a>(), etc. You can swap the width and height with
<a href="#transpose">transpose</a>(). You can get a size which holds the maximum height and
width of two sizes using <a href="#expandedTo">expandedTo</a>(), and the minimum height and
width of two sizes using <a href="#boundedTo">boundedTo</a>().

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="ScaleMode-enum"></a>TQSize::ScaleMode</h3>
<p> This enum type defines the different ways of scaling a size.
<p> <center><img src="scaling.png"></center>
<ul>
<li><tt>TQSize::ScaleFree</tt> - The size is scaled freely. The ratio is not preserved.
<li><tt>TQSize::ScaleMin</tt> - The size is scaled to a rectangle as large as possible
inside a given rectangle, preserving the aspect ratio.
<li><tt>TQSize::ScaleMax</tt> - The size is scaled to a rectangle as small as possible
outside a given rectangle, preserving the aspect ratio.
</ul><p> <p>See also <a href="#scale">TQSize::scale</a>(), <a href="tqimage.html#scale">TQImage::scale</a>(), and <a href="tqimage.html#smoothScale">TQImage::smoothScale</a>().

s.<a href="#rwidth">rwidth</a>() += 20; // s becomes (120,10)
</pre>
<p> <p>See also <a href="#rheight">rheight</a>().
<h3 class=fn>void <a name="scale"></a>TQSize::scale ( int w, int h, <a href="ntqsize.html#ScaleMode-enum">ScaleMode</a> mode )
</h3>

as small as possible outside (<em>w</em>, <em>h</em>), preserving the aspect ratio.
</ul>

<pre>
TQSize t1( 10, 12 );
t1.<a href="#scale">scale</a>( 60, 60, TQSize::<a href="#ScaleMode-enum">ScaleFree</a> );
