The present invention relates to a method and apparatus for showing user selectable options on the display screen of a data processing apparatus. The data processing apparatus includes a data processor, a display device incorporating a display screen, a display device driver, user entry means such as a mouse, keyboard or touch screen entry, and programming means to control the data processing apparatus. The programming is adapted to operate the display device driver to depict a control object or icon defining a data processing operation. The entry means is operable by the user to cause the system to perform the operation defined by the control object. The depiction of the control object comprises forward and reverse successions of images in which the amount of picture detail of the depiction is increased progressively through the succession of images and subsequently reduced progressively. The control object is thus made to appear to grow on the screen and subsequently to shrink from the screen. |
