<P>
<p>The <a href="QSizeF.html#QSizeF()"><tt>QSizeF</tt></a> class defines the size of a two-dimensional object using floating point precision.</p>
<p>A size is specified by a <a href="QSizeF.html#width()"><tt>width</tt></a> and a <a href="QSizeF.html#height()"><tt>height</tt></a>. It can be set in the constructor and changed using the <a href="QSizeF.html#setWidth(double)"><tt>setWidth</tt></a>, <a href="QSizeF.html#setHeight(double)"><tt>setHeight</tt></a>, or <a href="QSizeF.html#scale(com.trolltech.qt.core.QSizeF, com.trolltech.qt.core.Qt.AspectRatioMode)"><tt>scale</tt></a> functions, or using arithmetic operators. A size can also be manipulated directly by retrieving references to the width and height using the rwidth() and rheight() functions. Finally, the width and height can be swapped using the <a href="QSizeF.html#transpose()"><tt>transpose</tt></a> function.</p>
<p>The <a href="QSizeF.html#isValid()"><tt>isValid</tt></a> function determines if a size is valid. A valid size has both width and height greater than or equal to zero. The <a href="QSizeF.html#isEmpty()"><tt>isEmpty</tt></a> function returns true if either of the width and height is <i>less</i> than (or equal to) zero, while the <a href="QSizeF.html#isNull()"><tt>isNull</tt></a> function returns true only if both the width and the height is zero.</p>
<p>Use the <a href="QSizeF.html#expandedTo(com.trolltech.qt.core.QSizeF)"><tt>expandedTo</tt></a> function to retrieve a size which holds the maximum height and width of this size and a given size. Similarly, the <a href="QSizeF.html#boundedTo(com.trolltech.qt.core.QSizeF)"><tt>boundedTo</tt></a> function returns a size which holds the minimum height and width of this size and a given size.</p>
<p>The <a href="QSizeF.html#QSizeF()"><tt>QSizeF</tt></a> class also provides the <a href="QSizeF.html#toSize()"><tt>toSize</tt></a> function returning a <a href="QSize.html"><tt>QSize</tt></a> copy of this size, constructed by rounding the width and height to the nearest integers.</p>
<p><a href="QSizeF.html#QSizeF()"><tt>QSizeF</tt></a> objects can be streamed as well as compared.</p>
