THdrEvent specifies an event handler signalled when an event occurs in a column header. Arguments passed to the event handler indicate whether the action occurred for a column or a row header, and the index position for the row or column.
THdrEvent is the type used to implement the OnHeaderClick and OnHeaderSized properties in TCustomDrawGrid. Applications must implement an object procedure using the event signature to respond to the event notification.
