Rollover-Color
This property allows you to set or retrieve the color of the Push-Button control when the mouse pointer hovers over it. Foreground and background color values are combined and therefore RGB colors are not supported. See "Color management" for further details.
 
Example - Define a push-button with different background and foreground color on mouseover
screen section.
