TatScripterEventBroker Class

For event support.

Remarks

TatScripterEventBroker provides methods to set and remove event handlers, specifying the object, event name, and the script routine that should handle the event. The broker also implements a stack mechanism: setting a new handler does not necessarily discard the previous one -- the previous handler can optionally be kept in the call chain. When an event set by the broker is removed, the previous handler is automatically restored.

Syntax

Unit: atScript

TatScripterEventBroker = class(TComponent);
