UI Component Reference

Reference Generic UI System buttons, tabs, lists, widget factories, detail views, and current Unreal Engine APIs.

Created: Apr 15, 2025Updated: Oct 27, 2026

Scope

This page describes code components in GenericUISystem. The plugin contains no Widget Blueprints; your project supplies presentation, layout, and data adapters. See companion project content and example assets for inspectable examples.

Buttons and tabs

GUIS_ButtonBase is a base for project buttons; GUIS_TabButtonBase implements GUIS_TabButtonInterface. Derive your own button Widgets as needed. Tabs use GUIS_TabListWidgetBase and FGUIS_TabDescriptor: the descriptor includes a unique TabId, TabText, IconBrush, button class, and optional content class. The button class must implement GUIS_TabButtonInterface.

Configure preregistered descriptors on the tab list or use RegisterDynamicTab; associate the list with your Widget Switcher and test navigation. The old GUIS_TabDefinition and TabDefinitions are deprecated; use the current descriptor and PreregisteredTabInfoArray. GGF names and project Blueprints in old screenshots are historical examples.

Lists and detail views

GUIS_ListView and GUIS_TileView can use a GUIS_WidgetFactory to select an entry Widget for a data object. Implement the selection logic and provide your project's entry classes.

GUIS_ListEntryDetailView, GUIS_ListEntryDetailSection, and GUIS_DetailSectionsBuilder can divide an object's information into sections. Configure a suitable Builder and project Widgets, then display them in the required order.

Tip

An Item is usually an object displayed by a ListEntryWidget in a ListView, but it doesn't have to be.
