Label Line Wrapping - Custom Styles Tutorial [yFiles for HTML]

This step shows how to enhance a custom label style to support different line wrapping (trimming) styles as well as text clipping at the label bounds.

Description

MySimpleLabelStyle provides a property wrapping, which offers the option to switch between different TextWrapping styles. The value of the property is passed to TextRenderSupport#addText, which automatically takes care of the line wrapping.

Method clipText() adds a clip-path element to the label's DOM element, which clips the label text at the label bounds. This is only done if the text exceeds the bounds, i.e. when trimming is set to None and the text is long enough.

The label style is configured to use a fixed desired size to showcase the trimming feature.

Things to Try

Use the Wrapping box to switch between the different wrapping styles.
Edit the label text or create new labels to see the outcome.
