TAdvCustomComponentComboBox Class

Abstract base combo box that lists all components owned by a root component and keeps selection synchronized with a component inspector.

Remarks

TAdvCustomComponentComboBox extends TCustomComboBox to populate its items from the component hierarchy rooted at Root. Selecting an item automatically updates the Instance property of a linked TAdvCustomComponentInspector, and inspector changes are reflected back in the combo selection. Override Filter to restrict which components appear in the list.
