RichLinks

This is the official documentation for the RichLinks plugin on the Fab marketplace.

---

RichLinks is a lightweight Unreal Engine 5 plugin that enables mouse-events (enter/leave/click) for inline links inside URichTextBlock widgets. It's designed for UI developers who want to trigger events or show tooltips when users hover over specific words or tags in rich text.

Features

• Adds <link> tag support with real mouse-events (enter/leave/click)
• Clean integration with URichTextBlock via decorator
• Easy to use in both C++ and Blueprint widgets
• Tested with Unreal Engine 5.3

Installation

1. Copy ./Plugins/RichLinks into your project’s ./Plugins directory.
2. Regenerate project files and reopen the project.
3. Enable the RichLinks plugin in the editor under Edit -> Plugins.

Getting Started

Add the ULinkRichTextBlockDecorator to your URichTextBlock. Use the following tag to enable RichLink functionality:

This is an <link id="example">example link</>.

You can handle hover events directly through Slate or use Blueprint interfaces to receive callbacks.

Example Widget

1. Open W_PlainRichText
2. In the Designer tab, check out the Rich Text Block
3. Notice that a Text Style Set must be applied, here DT_RichTextStyle
4. Under Decorator classes, the LinkRichTextDecorator is required
5. In the Graph tab, check out how ILinkEventReceiver is implemented

You can create your own interfaces that implement ILinkEventReceiver and react to the link events NotifyOnLinkMouseEnter, NotifyOnLinkMouseLeave and NotifyOnLinkMouseButtonDown accordingly. For example OnMouseEnter / OnMouseLeave, you could spawn/destroy another WidgetActor as a tooltip and pass in the linkId for the tooltip to display the correct information.
