Description

HeaderSized is used to perform actions needed when the header for a column or row has been resized in the grid control.

IsColumn indicates whether the sizing action applies to a column or a row. When set to True, the column header has been resized. When set to False, the row header was resized.

Index indicates the column or row number in the grid where the resizing action occurred.

HeaderSized has an empty implementation in TCustomGrid. It is overidden in descendent classes like TCustomDrawGrid to perform additional actions.

HeaderSized is called from methods like MouseUp (when column or row sizing is completed) and DblClick (when column sizing is enabled in the grid Options).
