ImageObserver is an interface used to receive notification as an image is being generated, and it defines only one method: imageUpdate( ) Using an image observer allows you to perform other actions, such as show a progress indicator or an attract screen, as you are informed of the progress of the download This kind of notification is very useful when an image is being loaded over the network, where the content designer rarely appreciates that people are often trying to load applets over a slow modem The imageUpdate( ) method has this general form: boolean imageUpdate(Image imgObj, int flags, int left, int top, int width, int height) Here, imgObj is the image being loaded, and flags is an integer that communicates the status of the update report The four integers left, top, width, and height represent a rectangle that contains different values depending on the values passed in flags imageUpdate( ) should return false if it has completed loading, and true if there is more image to process The flags parameter contains one or more bit flags defined as static variables inside the ImageObserver interface These flags and the information they provide are listed in Table 25-1 The Applet class has an implementation of the imageUpdate( ) method for the ImageObserver interface that is used to repaint images as they are loaded You can override this method in your class to change that behavior

and you interact with the display by obtaining a reference to an instance of the MIDlet s Display class Each MIDlet has one and only one instance of the Display class Every J2ME MIDlet that displays anything on the screen must obtain a reference to its Display instance This instance is used to show instances of Displayable class on the screen The Displayable class has two subclasses These are the Screen class and the Canvas class The Screen class contains a subclass called the Item class, which has its own subclasses used to display information or collect information from a user (such as forms, check boxes, radio buttons) The Screen class and its derived classes are referred to as high-level user interface components The Canvas class is used to display graphical images such as those used for games Displays created using the Canvas class are considered a low-level user interface and are used whenever you need to display a customized screen Instances of classes derived from the Displayable class are placed on the screen by calling the setCurrent() method of the Display class The object that is to be displayed is passed to the setCurrent() method as a parameter It is important to note that instances of derived classes of the Item class are not directly displayable and must be contained within an instance of a Form class An instance of an Item class appears on the screen when the setCurrent() method is used to show the form The getCurrent() method of the Display class is used by a MIDlet to retrieve information about the instances of derivatives of the Displayable class You obtain an instance of the Display class by declaring a reference to the instance and then assigning the instance to the reference by invoking the getDisplay() method,
