Description
TLVSubItemImageEvent is the type of a list view's TCustomListView.OnGetSubItemImage and TListView.OnGetSubItemImage event handlers.
The Sender parameter is the list view that is being painted.
The Item parameter is the item whose subitem is being painted.
The SubItem parameter identifies the subitem from the list item's SubItems property.
The ImageIndex parameter is an index into the list view's SmallImages property. On entry to the event handler, ImageIndex is initialized to the value specified by the list item's SubItemImages property for the subitem. Use this event handler to change that value or to suppress the image by setting ImageIndex to –1.
