Class GestureLink

java.lang.Object
  jview.GestureLink

All Implemented Interfaces:

AWTEventListener, EventListener, ExitCleaning

public class GestureLink
extends Object
implements AWTEventListener, ExitCleaning

This class is the client class to a InputEventLinking instance. The correct usage could be summarized as:

• Create a GUI on the server side of any of the graphical applications.
• Create a GestureRobot within this GUI, initialize it with GestureRobot#setParent(), using the main GUI frame as its argument. Do this only after the GUI has been drawn on the screen.
• Export the GestureRobot to the registry using bind.
• On the client side, create an identical GUI as in the server. Take special care that the layout is identical.
• Within the client, create a gesture link and add this to the client Toolkit (getDefaultToolkit().addAWTEventListener).
• Link this client to the server using the linkTo(java.lang.String) method, using the Naming path to the gui server.
• Once the client has displayed itself, call attachTo(java.awt.Component) which calls GestureRobot.setClientDimension(java.awt.Dimension) with the actual client size. Again, take special care of identical layouts.
• Note that the mouse events generated in the client are all sent to the server, thus for slow connections, move the mouse slowly

Field Summary

private Component	display This is the component we link up.
private InputEventLinking	robot This is the gesture robot that will mimick our movements.

Constructor Summary

GestureLink()
Create a new gesture link.

GestureLink(String linkto)
Create a new gesture link and links it to the named server.

Method Summary

boolean	attachTo(Component c) We attach this component to the robot on the server side.
void	eventDispatched(AWTEvent event) We relay the event received to the server, it the server can interpret the event.
void	exit() On exit, we remove ourtself from the toolkit as a listener.
boolean	linkTo(String server) We try to look up the server at the given name.
static void	main(String[] arg) In the standalone version we try to connect to a gesture robot bound as the argument.
private void	transfer(InputEvent ie) We savly transfer the input event to a non-null robot.

Field Detail

robot

private InputEventLinking robot

This is the gesture robot that will mimick our movements.

display

private Component display

This is the component we link up.

Constructor Detail

GestureLink

public GestureLink()

Create a new gesture link. Before the linking can take place, a linked component must be attached.

GestureLink

public GestureLink(String linkto)

Create a new gesture link and links it to the named server. Before the linking can take place, a linked component must be attached.

Method Detail

exit

public void exit()

On exit, we remove ourtself from the toolkit as a listener.

Specified by:

exit in interface ExitCleaning

linkTo

public boolean linkTo(String server)

We try to look up the server at the given name. This method should always be called before attachTo(java.awt.Component)

attachTo

public boolean attachTo(Component c)

We attach this component to the robot on the server side. Only if the component's size can be determined, we add ourself as a listener to the root toolkit.

eventDispatched

public void eventDispatched(AWTEvent event)

We relay the event received to the server, it the server can interpret the event. In particular, these are MouseEvents if the mouse was moved or dragged, if a button was pressed or released (but not clicked, this event is ignored), or if the mouse wheel was turned, or key-pressed and key-released events.

Specified by:

eventDispatched in interface AWTEventListener

transfer

private void transfer(InputEvent ie)

We savly transfer the input event to a non-null robot.

main

public static void main(String[] arg)
                 throws RemoteException

In the standalone version we try to connect to a gesture robot bound as the argument.

Throws:

RemoteException
