System Documentation

What problem does it solve?

Developers struggle to understand how Gum's editor selection system coordinates input handlers, rectangle marquee selection, and locked instance behavior, leading to bugs and inefficient UI design.

Core Features & Use Cases

  • Input Handlers: Detailed mapping of Move, Resize, Rotation, and PolygonPoint handlers and their lifecycle.
  • Rectangle Selector: Explanation of marquee selection activation and its interaction with the IsActive flag.
  • Locking Mechanism: How InstanceSave.Locked is enforced across handlers and selection processes.
  • Selection Event Cascade: Order of plugin events when an instance is selected, including state selection and tree view synchronization.
  • Practical Scenario: Use the guide to modify a UI layout where certain elements are locked, ensuring the rectangle selector does not interfere with movement gestures.

Quick Start

Ask the skill to describe how to keep the rectangle selector from activating when moving a locked instance.
