Markup Labels

This demo shows how to create labels with rich text features using MarkupLabelStyle.

Since the MarkupLabelStyle supports basic HTML markup, it can be easily hooked up with a WYSIWYG text editor that completely hides the markup from the user, as demonstrated in the Rich Text Label Demo.

Creating and Editing Labels

Press the F2 key while an element or connection is selected.
Insert HTML-style markup text into the editor, i.e. <strong>Hello World</strong>

Supported Markup

The tags supported by rich text labels are

<span>: A stylable element.
<br>: Adds a line break
<em>: Italic text
<strong>: Bold text
<del>: Strikethrough text
<u>: Underline text
<h1>-<h6>: Heading 1-6
<p>: A paragraph element.
<pre>: A preformatted element which preserves newlines.
<code>: A code element.
<small>: Small font-size
<large>: Large font-size
<[html color name]>: Colored text, e.g. <blue>

Styling Labels with CSS

Tags can be styled with inline CSS. Also tags can be given CSS classes to use external CSS.

For example, the default <h2> is styled as dark gray with small-caps in this demo.

Text Wrapping

Markup labels can use line wrapping. In this demo application, the labels use word wrapping with ellipsis. Select and resize a node to observe the interactive text wrapping. Rich text labels can also be wrapped at character boundaries.
