<h2>Description</h2>
|
|
<p>The label displays a non interactive text.</p>
|
|
<p>The style flag enables to draw the label in two distinct styles. The first one is default <var>(style = 0)</var> and displays the label simply as text. The alternative <var>(style = 1)</var> displays the label with a frame around it. An example is shown in the following figure.</p>

<img alt="" src="../fpdoc/images/label.png">

|
|
|
<p>The <var>Text</var> variable can have multiple lines.</p>
