When performing development on Windows, the ComponentState property or DelphiVCL.Application.ComponentState is used to describe the current state of the component, indicating when a component needs to avoid certain actions.
ComponentState is a set of constants defined in the TComponentState type.
Components use the ComponentState property to detect states in which certain kinds of actions are allowed or disallowed. For example, if a component needs to avoid certain behaviors at design time that it performs at run time, it can check for the csDesigning flag.
ComponentState is read-only and its flags are set automatically when appropriate.
