UActorComponent::IsEditableWhenInherited

function Engine Since unknown

#include "Components/ActorComponent.h"

Access: public

Description

Returns true if this component can be modified when it was inherited from a parent actor class. Use this to guard property edits or construction-script logic that should only run on components the child actor actually owns.

Caveats & Gotchas

• A component that returns false here will have its properties locked to the parent class defaults in the Details panel; any programmatic modification at runtime still works but will not persist through serialization of the child blueprint.
• The result depends on the component's creation method (CreationMethod == EComponentCreationMethod::Native or SimpleConstructionScript). Dynamically added components (EComponentCreationMethod::Instance) are always considered editable.

Example

Guard property change to inherited components C++

void UMyComponent::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent)
{
    Super::PostEditChangeProperty(PropertyChangedEvent);
    if (!IsEditableWhenInherited())
    {
        // Silently skip — the property belongs to the parent class
        return;
    }
    RebuildData();
}
