Remarks

This function is called by a map item’s GetHint function to obtain a hint message for a map item (AItem) whose Hint property is assigned an empty string. The GetItemHint function fires the OnGetItemHint event and passes the default hint message specified by the ItemHint property and AItem as the event parameters. You can handle the event to customize the hint message. The resulting hint message is returned as the GetItemHint function’s result.
