Creating custom delphi components, part ii quite often it is necessary to write components that perform more advanced functions. these components often need to either reference other components, have custom property data formats, or have a property that owns a list of values rather than a single value. Defining custom actions. in addition to defining customcomponents, you can define and register new standard actions, which will be made available in the action list component’s action editor. creating new actions is not complex. you have to inherit from the taction class and override some of the methods of the base class.
