Description

THintEvent is the method pointer type used to define OnHint events.

Event handlers of the THintEvent type have the following parameters:

Parameter	Description
`HintStr`	The string that will appear in the pop-up help hint. The event handler can change this string to change the hint that appears to the user.
`CanShow`	Indicates whether the hint specified by `HintStr` should be shown using the default popup window after the event handler exits. Set this to `False` to suppress the default behavior when the event handler displays the hint.
