Description
TTabAction is the base class for action objects designed to respond to the buttons in a tabbed dialog.
TTabAction implements the common behavior for actions that operate on tabbed controls (TCustomTabControl descendants). Each descendant class is designed to perform a specific function in a tabbed dialog such as a wizard. Do not use TTabAction directly in an application. Instead, use a TTabAction descendant such as TNextTab or TPreviousTab.
TTabAction introduces the TabControl property, which specifies the page control or tab control on which this action operates. It ensures that the action is only enabled when the TabControl property is assigned to an enabled TPageControl or TTabControl object.
