The verticalMargin attribute specifies the number of pixels for the vertical touch margin. The vertical margin is a touch-insensitive margin inside the object’s top and bottom edges. If the operator presses the touch-insensitive margin, the button press is not registered. If the shape attribute is circle or ellipse, the touch margin applies to the button’s bounding box.
All button graphic object elements, as well as the numericInputCursorPoint, numericInputEnable, and stringInputEnable graphic object elements, contain this attribute.
