Description

Changes the value of HeightSumsNeedUpdate to True to indicate that the total height of the list view items has changed since the last time that the list view presentation calculated that height.

Subclasses of TAdapterListView that handle the presentation of the list view must change the value of HeightSumsNeedUpdate to False each time that they calculate the total height of the list view items and update the list view presentation accordingly.
