Parent Component Object

This node accesses the state object of the parent component.

The Parent Component Object node allows a child component to read or write data from its container.

The Parent Component Object node allows for communication up the component tree. A child component can use this to access properties defined in the Component Object node of its parent.

Inputs

Properties

Data	Description
Properties	A comma-separated list of property names to access from the parent.

Property Values

Data	Description
*	Dynamic inputs. Setting a value here updates the parent's state.

Actions

Signal	Description
Fetch	Manually refreshes values.

Outputs

Property Values

Data	Description
*	Dynamic outputs reading from the parent's state.

Changed Events

Signal	Description
* Changed	Triggered when the parent's property changes.

Usage

Use this for tight coupling between a container and its children, such as a "Tab Group" (Parent) and "Tab Button" (Child).

Example: Tab System

1. Parent (Tab Group): Has a Component Object with property activeTab.
2. Child (Tab Button): Has a Parent Component Object accessing activeTab.
3. Child Logic:
   • Reads activeTab to decide if it should look "active".
   • Writes to activeTab when clicked to switch tabs.

Detailed Behavior

• Tree Traversal: It searches up the visual tree to find the nearest ancestor that has a Component Object defined.
• Shared State: Multiple children accessing the same parent object share the same state.

Troubleshooting

• No Parent Found: If the component is used at the root level or the parent has no Component Object, this node will not work.
