Class QTEventCaster
java.lang.Object

+--quicktime.app.event.QTEventCaster
All Implemented Interfaces: java.util.EventListener, MouseButtonListener, MouseEnterExitListener, MouseMoveListener, MouseTargetListener, QTActionListener, QTMouseListener
public class QTEventCasterextends java.lang.Objectimplements java.util.EventListener, QTActionListener, MouseButtonListener, MouseMoveListener, MouseEnterExitListener, MouseTargetListener
The QTEventCaster is used to broadcast QTEvents to registered listeners.
There are two characteristics of the broadcaster that are worthy of note:
Broadcasters check whether the event is consumed before each invocation of
a listeners methods. Broadcasters also check to see if a given listener
is interested in an event based on the modifier filter (if defined by the listener)
before the event is passed onto the listener.

QTEventCaster
protected QTEventCaster(java.util.EventListener a,
java.util.EventListener b)
Parameters:a - listener-ab - listener-b
Method Detail
add
public static MouseButtonListener add(MouseButtonListener c,
MouseButtonListener d)
Adds action-listener-a with action-listener-b and
returns the resulting multicast listener.
Parameters:a - action-listener-ab - action-listener-b
remove
public static MouseButtonListener remove(MouseButtonListener l,
MouseButtonListener oldl)
Removes the old action-listener from action-listener-l and
returns the resulting multicast listener.
Parameters:l - action-listener-loldl - the action-listener being removed
mouseClicked
public void mouseClicked(QTMouseEvent e)
Invoked when the mouse has been clicked.
Specified by: mouseClicked in interface MouseButtonListener
mousePressed
public void mousePressed(QTMouseEvent e)
Invoked when a mouse button has been pressed.
Specified by: mousePressed in interface MouseButtonListener
matchModifierFilter
public boolean matchModifierFilter(int mods)
Specified by: matchModifierFilter in interface QTMouseListener
Following copied from interface: quicktime.app.event.QTMouseListener
Parameters:mods - the state of the modifier keys.Returns:true if a particular listener is interested in receiving the mouse event(s)
it is interested in with the given modifier state, or false if otherwise.
mouseReleased
public void mouseReleased(QTMouseEvent e)
Invoked when a mouse button has been released.
Specified by: mouseReleased in interface MouseButtonListener
add
public static MouseMoveListener add(MouseMoveListener c,
MouseMoveListener d)
remove
public static MouseMoveListener remove(MouseMoveListener l,
MouseMoveListener oldl)
Removes the old action-listener from action-listener-l and
returns the resulting multicast listener.
Parameters:l - action-listener-loldl - the action-listener being removed
mouseDragged
public void mouseDragged(QTMouseEvent e)
Invoked when a mouse button is pressed on a component and then
dragged. Mouse drag events will continue to be delivered to
the component where the first originated until the mouse button is
released (regardless of whether the mouse position is within the
bounds of the component).
Specified by: mouseDragged in interface MouseMoveListener
mouseMoved
public void mouseMoved(QTMouseEvent e)
Invoked when the mouse button has been moved on a component
(with no buttons no down).
Specified by: mouseMoved in interface MouseMoveListener
add
public static MouseEnterExitListener add(MouseEnterExitListener c,
MouseEnterExitListener d)
remove
public static MouseEnterExitListener remove(MouseEnterExitListener l,
MouseEnterExitListener oldl)
Removes the old action-listener from action-listener-l and
returns the resulting multicast listener.
Parameters:l - action-listener-loldl - the action-listener being removed
mouseEntered
public void mouseEntered(QTMouseEvent e)
Invoked when the mouse enters a component.
Specified by: mouseEntered in interface MouseEnterExitListener
mouseExited
public void mouseExited(QTMouseEvent e)
Invoked when the mouse exits a component.
Specified by: mouseExited in interface MouseEnterExitListener
add

MouseTargetListener d)
remove
public static MouseTargetListener remove(MouseTargetListener l,
MouseTargetListener oldl)
mouseTargetEntered
public void mouseTargetEntered(QTMouseEvent e)

public void mouseTargetExited(QTMouseEvent e)
Invoked when a mouseMoved event exits a Target within an enclosing space. The target of a MouseResponder is set for events of this kind.
Specified by: mouseTargetExited in interface MouseTargetListener
Parameters:e - the QTMouseEvent that triggered this event
add
public static QTActionListener add(QTActionListener c,
QTActionListener d)
Adds action-listener-a with action-listener-b and
returns the resulting multicast listener.
Parameters:a - action-listener-ab - action-listener-b
remove
public static QTActionListener remove(QTActionListener l,
QTActionListener oldl)
Removes the old action-listener from action-listener-l and
returns the resulting multicast listener.
Parameters:l - action-listener-loldl - the action-listener being removed
actionPerformed
public void actionPerformed(QTActionEvent e)
Broadcasts the event to any interested QTActionListeners.
If the event is consumed it will not be broadcast to any further
listeners.
Specified by: actionPerformed in interface QTActionListener
addListener
protected static java.util.EventListener addListener(java.util.EventListener a,
java.util.EventListener b)
Returns the resulting multicast listener from adding listener-a
and listener-b together.
If listener-a is null, it returns listener-b;
If listener-b is null, it returns listener-a
If neither are null, then it creates and returns
a new AWTEventMulticaster instance which chains a with b.
Parameters:a - event listener-ab - event listener-b
removeListener
protected static java.util.EventListener removeListener(java.util.EventListener l,
java.util.EventListener oldl)
Returns the resulting multicast listener after removing the
old listener from listener-l.
If listener-l equals the old listener OR listener-l is null,
returns null.
Else if listener-l is an instance of AWTEventMulticaster,
then it removes the old listener from it.
