Methods Summary
public void	callInvalidate(javax.microedition.lcdui.Item src) Called by event delivery to process a Form invalidation param src the Item which may have caused the invalidation
public void	callItemStateChanged(javax.microedition.lcdui.Item src) Called by event delivery to notify an ItemStateChangeListener of a change in an item param src the Item which has changed
public void	callSerially() Called by event delivery to batch process all pending serial callbacks
public void	commandAction(int id) Called by event delivery when an abstract Command is fired. The parameter is an index into the list of Commands that are current, i.e. those associated with the visible Screen. param id The integer id of the Command that fired (as returned by Command.getID())
public void	inputMethodEvent(java.lang.String str) Called by event delivery when an input method event is processed. param str The string from the input method.
public void	keyEvent(int type, int keyCode) Called by event delivery when a key event is processed. The type is one of EventHandler.PRESSED, EventHandler.RELEASED, or EventHandler.REPEATED. param type The type of event (press, release or repeat) param keyCode The key code for the key that registered the event
public void	pointerEvent(int type, int x, int y) Called by event delivery when a pen event is processed. The type is one of EventHandler.PRESSED, EventHandler.RELEASED, or EventHandler.DRAGGED. param type The type of event (press, release or drag) param x The x coordinate of the location of the pen param y The y coordinate of the location of the pen
public void	repaint(int x1, int y1, int x2, int y2, java.lang.Object target) Called by event delivery when a repaint should occur param x1 The origin x coordinate of the repaint region param y1 The origin y coordinate of the repaint region param x2 The bounding x coordinate of the repaint region param y2 The bounding y coordinate of the repaint region param target The optional paint target
public void	resumePainting() Called when the system is ready to give up its control over the screen. The application should receive a request for a full repaint when this is called, and is subsequently free to process paint events from Canvas.repaint(), Canvas.serviceRepaints() or internal paint methods on Displayable.
public void	suspendPainting() Called when the system needs to temporarily prevent the application from painting the screen. The primary use of this method is to allow a system service to temporarily utilize the screen, e.g. to provide input method or abstract command processing. This method should prevent application-based paints (i.e. those generated by Canvas.repaint(), Canvas.serviceRepaints() or some internal paint method on another kind of Displayable) from changing the contents of the screen in any way.
