When this style is set, the Push-Button control has no 3-D effect.
When the mouse pointer is moved over the Push-Button control, it is highlighted. The hihlight effect is controlled by the following properties: Rollover-Background-Color, Rollover-Border-Color, Rollover-Color and Rollover-Foreground-Color. If none of these properties is set, the highlight effect is applied only to buttons with an icon and it depends on the current Look and Feel.
