What is the DelphiVCL.Application.OnHint event?
The OnHint or DelphiVCL.Application.OnHint occurs when the mouse pointer moves over a control or menu item that can display a Help Hint. This mainly applies to Windows app development.
How to use the DelphiVCL.Application.OnHint event properly?
Write an OnHint event handler to perform special processing when the mouse pauses over a control or menu item whose Hint property is not an empty string.
A common use of the OnHint event is to display the value of a control or menu item’s Hint property in another control. Note that it is not necessary to use an OnHint event handler to display hints on a status bar. The status bar will automatically display hints if you set its AutoHint property to True.
Note: You can also respond to this event using the TApplicationEvents component, which allows you to assign an event handler using the IDE.
