ABSTRACT:
Methods and apparatuses for altering the appearance of an icon box when an event effecting the icon box occurs are disclosed. In one embodiment, a pointer entering an icon box or exiting an icon box is detected and an icon property is set accordingly. Also detected is an icon being set to activate its underlying function and the actual activation of an icon's underlying function. Another icon property is set based on whether an icon is set to be activated or has been activated. A repaint procedure is used to retrieve a new icon image and replace the image in the icon before the event occurred. The repaint procedure uses an icon label and the icon property states to determine which image to retrieve and place in the icon box. The repaint method retrieves an image from a plurality of images reflecting different states of the icon. The icon is also capable of communicating any events effecting it to its parent object, such as a toolbar, thereby allowing the parent object to behave in an appropriate manner.
