TCustomListBox.SelectAll procedure
Selects all items in the list (in ExtendedSelect mode).
Declaration
procedure SelectAll; virtualDescription
SelectAll is a procedure used to mark all of the values defined in
the
Items property as
Selected. No actions are
performed in the method when Items is empty (Count is 0). SelectAll calls the
SelectRange method to select items at position 0 (zero) through
Count-1 (inclusive).
Use Selected to change the selection state for an individual item when
MultiSelect is enabled. Set ItemIndex to -1 to clear
the current selection when MultiSelect is not used.
