gui

Build and drive on-screen UI in one call — stand up a screen, change what it shows, react to it, and read its state back.

Create and show a screen from a widget list in a single step, then show, hide, or toggle it. Update a widget's properties in place by id. Switch the active theme or list the registered themes. Drive interaction synthetically the way a test or an agent would: press, type and set use an element by its id — an editor panel's or the game's UI — without moving the pointer or anyone's keyboard focus; clickElement, hoverElement and dragElement aim the pointer at it; click fires a callback id; scroll turns the wheel. And introspect: read a screen's widget tree, list the available widget types, or get the property definitions for a given type. The inspection operations hand back tables; the rest act on the live UI.
