Syntax

<Result> = ControlOver([<Invisible Controls> [, <Hovered Window>]])

<Result>: Character string

Name of the control, column or window hovered by the mouse cursor.
Empty string ("") if no control is hovered by the mouse cursor.

<Invisible Controls>: Optional boolean

True if the invisible controls must be taken into account.
False (by default) if the invisible controls must not be taken into account.

<Hovered Window>: Optional boolean

True if the name of the window must be returned when no control is hovered by the mouse cursor,
False (default) if an empty string must be returned when no control is hovered by the mouse cursor.

Remarks

Control hovered by the mouse cursor

If several controls are hovered by the mouse cursor, the name of the control with the highest z-order position is returned (which means the name of the control in the foreground).
If a table column is hovered by the mouse cursor, the name of the column is returned.
The controls not found in the active plane are considered as being invisible.
