The pictureRollUnder property of the JadeMask class contains the picture that is displayed when the mouse is over the control or the control has focus and the button is in the down position (that is, value = true).
See also the picture, pictureDown, pictureDisabled, pictureRollOver, and pictureMask properties.
If the value of the pictureIndex property is not zero (0), the picture determined by the pictureIndex property is always displayed unless the control is disabled or the mouse is currently pressed on the control (the picture determined by the value of the pictureDown property is displayed).
If the value of the pictureRollUnder property is null, the pictureDown property picture is displayed when the value property is true and the mouse moves over the control or the control has focus.
