This implementation follows the existing event dispatcher pattern used throughout the library. - -## Overview - -The WindowManager class now includes event dispatching capabilities that allow you to listen for various window lifecycle events such as creation, destruction, focus changes, resizing, and movement. - -## Supported Events - -The following window events are supported: - -- `WindowCreatedEvent` - Fired when a new window is created -- `WindowClosedEvent` - Fired when a window is closed -- `WindowFocusedEvent` - Fired when a window gains focus -- `WindowBlurredEvent` - Fired when a window loses focus -- `WindowMinimizedEvent` - Fired when a window is minimized -- `WindowMaximizedEvent` - Fired when a window is maximized -- `WindowRestoredEvent` - Fired when a window is restored from minimized/maximized state -- `WindowMovedEvent` - Fired when a window is moved (includes new position) -- `WindowResizedEvent` - Fired when a window is resized (includes new size) - -## Usage - -### Adding Listeners - -You can add event listeners in two ways: - -#### 1.
