onRefresh - event of object PmiItem

The event fires on the refresh of the item data.
pMe(Object) Reference to the graphic item where the event rises.
pEvent(Object) A referrence to object describing detailed information about the specific event.

The pEvent parameter is not used here because this event does not need any additional information.

This event is also functional for Web panels.
The data of the item are refreshed either:
- when the panel is automatically redrawn - if this panel hasn't set the Refresh period (refresh) configurator or
- after calling the PmiItem.Refresh method or
- after calling the PmPanel.Refresh method (obsolete).

The event can be used, for example, for the data refresh in the graphic item (replacement of data bindings).
