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>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Type-enum" />QTextLength.Type</h3><p>This enum describes the different types a length object can
have.</p>

<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QTextLength" />QTextLength.__init__ (<i>self</i>)</h3><p>Constructs a new length object which represents a variable
size.</p>
<h3 class="fn"><a name="QTextLength-2" />QTextLength.__init__ (<i>self</i>, <a href="qtextlength.html#Type-enum">Type</a> <i>atype</i>, float <i>avalue</i>)</h3><p>Constructs a new length object of the given <i>type</i> and
<i>value</i>.</p>
<h3 class="fn"><a name="QTextLength-3" />QTextLength.__init__ (<i>self</i>, QVariant <i>variant</i>)</h3><h3 class="fn"><a name="QTextLength-4" />QTextLength.__init__ (<i>self</i>, <a href="qtextlength.html">QTextLength</a>)</h3><h3 class="fn"><a name="rawValue" />float QTextLength.rawValue (<i>self</i>)</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>
<h3 class="fn"><a name="type" /><a href="qtextlength.html#Type-enum">Type</a> QTextLength.type (<i>self</i>)</h3><p>Returns the type of this length object.</p>
