TCustomListBox.SelCount property
The number of selected items in the list box control.
Declaration
property SelCount: Integer read GetSelCount;Description
SelCount is a read-only
Integer property which contains
the number of
Items selected in the list box control. The property
value is the result returned by the
GetSelCount method
in the widgetset class when its Handle has been allocated.
If the widget Handle is unassigned, the property value is determined using either the value in ItemIndex or the list items in the local cache. If MultiSelect has not been enabled, the property value is either 0 or 1; 0 when ItemIndex = -1 and 1 when ItemIndex > -1. If MultiSelect is True, the local item cache is searched to get the number of items selected in the control. The value is 0 if the local cache is invalid or none of the cached items are in the selected state.
Use Selected to get or set the selected state for an item on the
control.
Use SelectRange to set or reset the selected state for Items in a
specified range of positions.
Use SelectAll to select all Items in the control.
Use ClearSelection to remove all item selections in the control.
