Description
Registers the options associated with a control that is enabled for observing.
moTrack is an observable member option that is related to the Track property. moTrack indicates that the default value for Track is True for a particular type of control (such as TListView or TCustomDateTimeEdit).
The Track option means that notifications are sent more frequently. Here is a run-time example using a TCheckBox that is bound to a field in a database table:
- If Track is set for the checkbox, the change occurs immediately when you click the checkbox.
- If Track is not set, the change does not occur until the checkbox control loses focus.
