NextItem method

Applies To
TQDB, TQDBItem, TQDBView

Declaration
procedure NextItem;

Description

In TQDB
The NextItem method moves to the next item whose key matches the Filter pattern.

A call to NextItem, when it actually moves to a different item, generates an OnNavigate event. EoF may also be set (see AggressiveUpdate). If ItemIndex already points to the unfiltered last entry NextItem generates the EQDBOutOfBounds exception or, if a handler for it has been assigned, the WarnOutOfBounds event.

In TQDBItem
As above but also loads the next item and parses it into fields.

In TQDBView
As above but also displays the next item in the Panel.
