Game.UI.Widgets.IExpandable

Assembly: Assembly-CSharp
Namespace: Game.UI.Widgets

Type: interface

Base: —

Summary:
Interface for UI widgets that support an expanded/collapsed state. Implement this on widgets that can be shown or hidden (or that change layout/size) when toggled; the simple boolean property allows UI layout code and other systems to read or set the expansion state.

---

Fields

• None.
  {{ The interface defines no fields. }}

Properties

• public System.Boolean expanded { get; set; }
  Controls whether the widget is in its expanded (true) or collapsed (false) state. Implementors should update visual/layout changes when this property is changed (for example, trigger animations or call layout invalidation).

Constructors

• None.
  {{ Interfaces do not define constructors. Implementing types supply their own constructors or lifecycle methods. }}

Methods

• None.
  {{ The interface exposes no methods; behavior is driven via the expanded property. }}

Usage Example

// Example implementation of IExpandable on a widget
public class MyExpandableWidget : UIComponent, IExpandable
{
    private bool _expanded;

    public bool expanded
    {
        get => _expanded;
        set
        {
            if (_expanded == value) return;
            _expanded = value;
            UpdateExpansionState();
        }
    }

    private void UpdateExpansionState()
    {
        if (_expanded)
        {
            // expand: enable content, play animation, update layout, etc.
        }
        else
        {
            // collapse: hide content, play animation, update layout, etc.
        }

        // If using a layout system, notify it to re-layout:
        // InvalidateLayout();
    }
}

Notes: - Implementors should ensure changing expanded leads to appropriate visual and layout updates. - Consider persisting the expanded state if the widget's visibility should be remembered across sessions.
