<div class="textblock"><p>A class representing a text. </p>
<p>A <a class="el" href="class_qwt_text.html" title="A class representing a text.">QwtText</a> is a text including a set of attributes how to render it.</p>
<ul>
<li>Format<br/>
A text might include control sequences (f.e tags) describing how to render it. Each format (f.e MathML, TeX, Qt Rich Text) has its own set of control sequences, that can be handles by a <a class="el" href="class_qwt_text_engine.html" title="Abstract base class for rendering text strings.">QwtTextEngine</a> for this format.</li>
<li>Background<br/>
A text might have a background, defined by a QPen and QBrush to improve its visibility.</li>
<li>Font<br/>
A text might have an individual font.</li>
<li>Color<br/>
A text might have an individual color.</li>
<li>Render Flags<br/>
Flags from Qt::AlignmentFlag and Qt::TextFlag used like in QPainter::drawText.</li>

Layout the text without its margins. This mode is useful if a text needs to be aligned accurately, like the tick labels of a scale.

<p>The text format defines the <a class="el" href="class_qwt_text_engine.html" title="Abstract base class for rendering text strings.">QwtTextEngine</a>, that is used to render the text.</p>
<ul>
<li>AutoText<br/>

Draw the text as it is, using a <a class="el" href="class_qwt_plain_text_engine.html" title="A text engine for plain texts.">QwtPlainTextEngine</a>.</li>
<li>RichText<br/>
Use the Scribe framework (Qt Rich Text) to render the text.</li>
<li>MathMLText<br/>
Use a MathML (<a href="http://en.wikipedia.org/wiki/MathML">http://en.wikipedia.org/wiki/MathML</a>) render engine to display the text. The Qwt MathML extension offers such an engine based on the MathML renderer of the Qt solutions package. Unfortunately it is only available for owners of a commercial Qt license.</li>
<li>TeXText<br/>
Use a TeX (<a href="http://en.wikipedia.org/wiki/TeX">http://en.wikipedia.org/wiki/TeX</a>) render engine to display the text.</li>
<li>OtherFormat<br/>
The number of text formats can be extended using setTextEngine. Formats >= OtherFormat are not used by Qwt.</li>
