TCustomListView.UpdateColumn Method

Individual column update event dispatcher.

Pascal
procedure UpdateColumn(AnIndex: Integer);
C++
__fastcall UpdateColumn(int AnIndex);

UpdateColumn is called automatically when the display properties of a column in the list view change. UpdateColumn adjusts the image of the column to match the properties of the TListColumn object indexed by the AnIndex parameter in the Columns property. 

UpdateColumn does nothing if ColumnsShowing returns false.
