TCustomGrid.InvalidateCol procedure
Invalidates all cells in the specified column, and causes them to be redrawn.
Declaration
procedure InvalidateCol(ACol: Integer)Arguments
ACol | Column number for the cells invalidated in the method. |
Description
InvalidateCol is a method used to refresh all cells in the column
number specified in the ACol argument. InvalidateCol gets a TRect instance
with the bounds for cells in the specified column number. It calls the
InvalidateRect routine in the LCL interface using the Handle for the control
and the display rectangle as arguments.
No actions are performed in the method if a Handle has not been allocated in the widgetset class instance for the control.
InvalidateCol is not used in the current LCL version. Invalidate is called
instead.
