<h2>Detailed Description</h2>
<p>The QTextLength class encapsulates the different types of length used in a <a href="qtextdocument.html">QTextDocument</a>.</p>
<p>When we specify a value for the length of an element in a text document, we often need to provide some other information so that the length is used in the way we expect. For example, when we specify a table width, the value can represent a fixed number of pixels, or it can be a percentage value. This information changes both the meaning of the value and the way it is used.</p>
<p>Generally, this class is used to specify table widths. These can be specified either as a fixed amount of pixels, as a percentage of the containing frame's width, or by a variable width that allows it to take up just the space it requires.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/QTextLength/QTextLength"></a>
<h3 class="fn"><a name="QTextLength"></a>QTextLength::QTextLength ()</h3>
<p>Constructs a new length object which represents a variable size.</p>
<h3 class="fn"><a name="QTextLength-2"></a>QTextLength::QTextLength ( <a href="qtextlength.html#Type-enum">Type</a> <i>type</i>, <a href="qtglobal.html#qreal-typedef">qreal</a> <i>value</i> )</h3>
<p>Constructs a new length object of the given <i>type</i> and <i>value</i>.</p>
<a name="//apple_ref/cpp/instm/QTextLength/rawValue"></a>
<h3 class="fn"><a name="rawValue"></a><a href="qtglobal.html#qreal-typedef">qreal</a> QTextLength::rawValue () const</h3>
<p>Returns the constraint value that is specific for the type of the length. If the length is <a href="qtextlength.html#Type-enum">QTextLength::PercentageLength</a> then the raw value is in percent, in the range of 0 to 100. If the length is <a href="qtextlength.html#Type-enum">QTextLength::FixedLength</a> then that fixed amount is returned. For variable lengths, zero is returned.</p>
<a name="//apple_ref/cpp/instm/QTextLength/type"></a>
<h3 class="fn"><a name="type"></a><a href="qtextlength.html#Type-enum">Type</a> QTextLength::type () const</h3>
<p>Returns the type of this length object.</p>
<p>See also <a href="qtextlength.html#Type-enum">QTextLength::Type</a>.</p>
<a name="//apple_ref/cpp/instm/QTextLength/value"></a>
<h3 class="fn"><a name="value"></a><a href="qtglobal.html#qreal-typedef">qreal</a> QTextLength::value ( <a href="qtglobal.html#qreal-typedef">qreal</a> <i>maximumLength</i> ) const</h3>
<p>Returns the effective length, constrained by the type of the length object and the specified <i>maximumLength</i>.</p>
<p>See also <a href="qtextlength.html#type">type</a>().</p>
<a name="//apple_ref/cpp/instm/QTextLength/operator QVariant"></a>
<h3 class="fn"><a name="operator-QVariant"></a>QTextLength::operator QVariant () const</h3>
<p>Returns the text length as a <a href="qvariant.html">QVariant</a></p>
<a name="//apple_ref/cpp/instm/QTextLength/operator!="></a>
<h3 class="fn"><a name="operator-not-eq"></a>bool QTextLength::operator!= ( const QTextLength & <i>other</i> ) const</h3>
<p>Returns true if this text length is different from the <i>other</i> text length.</p>
<a name="//apple_ref/cpp/instm/QTextLength/operator=="></a>
<h3 class="fn"><a name="operator-eq-eq"></a>bool QTextLength::operator== ( const QTextLength & <i>other</i> ) const</h3>
<p>Returns true if this text length is the same as the <i>other</i> text length.</p>
