    delete an element from the list.

    Declaration

    Source position: fgl.pp line 85

    public 
procedure TFPSList.Extract(Item: Pointer; ResultPtr: Pointer);

    Description

    Extract removes the item pointed to by Item from the list. It returns a pointer to the actually removed item from the list. The item is searched using TFPSList.IndexOf. If the item is not found, nil is returned.

    Some descendents own the items in the list. Extract will not dispose of the item, as TFPSList.Delete does.

    Errors

    None.
