WindowManager

Owns a collection of Window instances, handles their lifecycle (creation, persistence, disposal), z-order, and placement. Use one WindowManager per panel/viewport. Windows are obtained via the GetWindow<T>(id) factory, which returns the existing instance on subsequent calls (singleton-per-(type, id)).

Position and size are persisted to PlayerPrefs under a configurable prefix. A separate index key tracks all stored window ids so ClearAllStoredPlacements() can remove them without scanning all of PlayerPrefs.

Constructor

var manager = new WindowManager();
parent.Add(manager.BuildVisualElement());

Examples

Single manager, multiple windows

var manager = new WindowManager();
rootPanel.Add(manager.BuildVisualElement());

manager.GetWindow<InventoryWindow>();          // id defaults to "Common"
manager.GetWindow<ChatWindow>("guild");
manager.GetWindow<ChatWindow>("party");        // distinct second instance of ChatWindow

Custom preference prefix (per-save-slot windows)

var manager = new WindowManager { PreferenceKeyPrefix = $"Save{slotId}.Window" };

Reset all stored placements

manager.ClearAllStoredPlacements();   // clears persisted positions/sizes; existing windows are not closed

Programmatic close

var inventory = manager.GetWindow<InventoryWindow>();
inventory.Close();
