Class LwEventManager

java.lang.Object

  +--org.zaval.lw.event.LwEventManager

All Implemented Interfaces:

LwManager

public class LwEventManager

extends java.lang.Object

implements LwManager

This is one of the core classes of the light weight library that is used to define light weight events delivering strategy. Actually all light weight components events at first are passed to the manager and after that the manager decides how the events should be delivered.

The manager provides listeners supporting for following events types:

• Light weight component events listeners supporting. Use addComponentListener and removeComponentListener methods.
• Light weight container events listeners supporting. Use addContainerListener and removeContainerListener methods.
• Light weight mouse events listeners supporting. Use addMouseListener and removeMouseListener methods.
• Light weight mouse motion events listeners supporting. Use addMouseMotionListener and removeMouseMotionListener methods.
• Light weight key events listeners supporting. Use addKeyListener and removeKeyListener methods.
• Light weight focus events listeners supporting. Use addFocusListener and removeFocusListener methods.
• Light weight wundow events listeners supporting. Use addWinListener and removeWinListener methods.

The manager provides universal methods to register and unregister light weight listeners, the method checks if the object implements one of the events listeners and calls appropriate method (see list above) to register or unregister appropriate listeners. Use addXXXListener and removeXXXListener for the purposes.

Method Detail

addXXXListener

public void addXXXListener(java.util.EventListener l)

Adds the specified events listener. The method checks what light weight listeneres interfaces are implemented with the listener and adds the events listeners as appropriate light weight events listeners.

Parameters:

l - the specified events listener.

removeXXXListener

public void removeXXXListener(java.util.EventListener l)

Removes the specified events listener. The method checks what light weight listeneres interfaces are implemented with the listener and removes the events listeners from the appropriate listners lists.

Parameters:

l - the specified events listener.

addComponentListener

public void addComponentListener(LwComponentListener l)

Adds the specified component events listener.

Parameters:

l - the specified events listener.

removeComponentListener

public void removeComponentListener(LwComponentListener l)

Removes the specified component events listener.

Parameters:

l - the specified events listener.

addContainerListener

public void addContainerListener(LwContainerListener l)

Adds the specified container events listener.

Parameters:

l - the specified events listener.

removeContainerListener

public void removeContainerListener(LwContainerListener l)

Removes the specified container events listener.

Parameters:

l - the specified events listener.

addMouseListener

public void addMouseListener(LwMouseListener l)

Adds the specified mouse events listener.

Parameters:

l - the specified events listener.

removeMouseListener

public void removeMouseListener(LwMouseListener l)

Removes the specified mouse events listener.

Parameters:

l - the specified events listener.

addMouseMotionListener

public void addMouseMotionListener(LwMouseMotionListener l)

Adds the specified mouse motion events listener.

Parameters:

l - the specified events listener.

removeMouseMotionListener

public void removeMouseMotionListener(LwMouseMotionListener l)

Removes the specified mouse motion events listener.

Parameters:

l - the specified events listener.

addFocusListener

public void addFocusListener(LwFocusListener l)

Adds the specified focus events listener.

Parameters:

l - the specified events listener.

removeFocusListener

public void removeFocusListener(LwFocusListener l)

Removes the specified focus events listener.

Parameters:

l - the specified events listener.

addKeyListener

public void addKeyListener(LwKeyListener l)

Adds the specified key events listener.

Parameters:

l - the specified events listener.

removeKeyListener

public void removeKeyListener(LwKeyListener l)

Removes the specified key events listener.

Parameters:

l - the specified events listener.

removeWinListener

public void removeWinListener(LwWinListener l)

Removes the specified window listener.

Parameters:

l - the specified window listener.

addWinListener

public void addWinListener(LwWinListener l)

Adds the specified window listener.

Parameters:

l - the specified events listener.

dispose

public void dispose()

Specified by:

dispose in interface LwManager

perform

public void perform(LwAWTEvent e)

Performs the specified light weight event. The method is used to distribute the event according the manager functionality and it is utilized with different parts of the library.

Parameters:

e - the specified light weight event.

getEventDestination

public LwComponent getEventDestination(LwComponent target)

Gets the event destination. The method looks for composite parent of the specified target component and defines if the parent should be the event destination

Parameters:

target - the specified target component.

Returns:

an event destination.
