WindowEvent JDK 1.6)

Constructors

public WindowEvent (Window source, int id)

Constructs a WindowEvent object.

Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.
Parameters:
- source - the Window object that originated the event
- id - an integer indicating the type of event
Throws:
- IllegalArgumentException - if source is null

public WindowEvent (Window source, int id, int oldState, int newState)

Constructs a WindowEvent object with the specified previous and new window states.

Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.
Parameters:
- source - the Window object that originated the event
- id - WINDOW_STATE_CHANGED event type. It is expected that this constructor will not be used for other WindowEvent types, because the previous and new window states are meaningless for other event types.
- oldState - an integer representing the previous window state
- newState - an integer representing the new window state
Throws:
- IllegalArgumentException - if source is null
Since: 1.4

public WindowEvent (Window source, int id, Window opposite)

Constructs a WindowEvent object with the specified opposite Window.

Constructs a WindowEvent object with the specified opposite Window. The opposite Window is the other Window involved in this focus or activation change. For a WINDOW_ACTIVATED or WINDOW_GAINED_FOCUS event, this is the Window that lost activation or focus. For a WINDOW_DEACTIVATED or WINDOW_LOST_FOCUS event, this is the Window that gained activation or focus. If this focus change occurs with a native application, with a Java application in a different VM, or with no other Window, then the opposite Window is null.

Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.
Parameters:
- source - the Window object that originated the event
- id - WINDOW_ACTIVATED, WINDOW_DEACTIVATED, WINDOW_GAINED_FOCUS, or WINDOW_LOST_FOCUS. It is expected that this constructor will not be used for other WindowEvent types because the opposite Window of such events will always be null
- opposite - the other Window involved in the focus or activation change, or null
Throws:
- IllegalArgumentException - if source is null
Since: 1.4

public WindowEvent (Window source, int id, Window opposite, int oldState, int newState)

Constructs a WindowEvent object.

Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.
Parameters:
- source - the Window object that originated the event
- id - an integer indicating the type of event.
- opposite - the other window involved in the focus or activation change, or null
- oldState - previous state of the window for window state change event
- newState - new state of the window for window state change event
Throws:
- IllegalArgumentException - if source is null
Since: 1.4
