Description
TActionLink is the base class for action links that connect actions to commonly used properties of VCL objects, components, and controls.
Most applications do not work directly with TActionLink objects. Instead, the clients of actions already include a specialized TActionLink descendant that manages the relationship between the client object and an action. TActionLink introduces methods to manage the relationship between properties of an action object and the corresponding properties of the client object. Descendant classes override these methods, implementing them for the particular properties of a class of client.
Component writers can use TActionLink as a base class for new action link classes that manage the relationship between actions and families of client objects that are not controls or menu items.
TActionLink introduces interfaces for methods that support the following properties, most of which are linked with properties of the same name:
- Caption
- Checked
- Enabled
- HelpContext
- Hint
- ImageIndex
- ShortCut
- Visible
