java.awt.event
Class WindowEvent
- Serializable
This event is generated when there is a change in a window. This includes
creation, closing, iconification, activation, and focus changes. There
are three listeners, for three types of events: WindowListeners deal with
the lifecycle of a window, WindowStateListeners deal with window state
like maximization, and WindowFocusListeners deal with focus switching to
or from a window.
static int | WINDOW_ACTIVATED - This is the id for a window that is activated.
|
static int | WINDOW_CLOSED - This is the id for a window that finished closing.
|
static int | WINDOW_CLOSING - This is the id for a window that is about to close.
|
static int | WINDOW_DEACTIVATED - This is the id for a window that is de-activated.
|
static int | WINDOW_DEICONIFIED - This is the id for a window that is de-iconified.
|
static int | WINDOW_FIRST - This is the first id in the range of event ids used by this class.
|
static int | WINDOW_GAINED_FOCUS - This is the id for a window becoming the focused window.
|
static int | WINDOW_ICONIFIED - This is the id for a window that is iconified.
|
static int | WINDOW_LAST - This is the last id in the range of event ids used by this class.
|
static int | WINDOW_LOST_FOCUS - This is the id for a window losing all focus.
|
static int | WINDOW_OPENED - This is the id for a window that is opened.
|
static int | WINDOW_STATE_CHANGED - This is the id for a window state change, such as maximization.

WindowEvent
public WindowEvent(Window source,
int id)
Initializes a new instance of WindowEvent
with the specified
parameters. Note that an invalid id leads to unspecified results.
source
- the window that generated this eventid
- the event id
WindowEvent
public WindowEvent(Window source,
int id,
int oldState,
int newState)
Initializes a new instance of WindowEvent
with the specified
parameters. Note that an invalid id leads to unspecified results.
source
- the window that generated this eventid
- the event idoldState
- the previous state of this windownewState
- the new state of this window
WindowEvent
public WindowEvent(Window source,
int id,
Window opposite)
Initializes a new instance of WindowEvent
with the specified
parameters. Note that an invalid id leads to unspecified results.
source
- the window that generated this eventid
- the event idopposite
- the window that received the opposite event, or null
WindowEvent
public WindowEvent(Window source,
int id,
Window opposite,
int oldState,
int newState)
Initializes a new instance of WindowEvent
with the specified
parameters. Note that an invalid id leads to unspecified results.
source
- the window that generated this eventid
- the event idopposite
- the window that received the opposite event, or nulloldState
- the previous state of this windownewState
- the new state of this window
getNewState
public int getNewState()
Returns the state of this window after the event. This is the bitwise
or of fields in Frame: NORMAL, ICONIFIED, MAXIMIZED_HORIZ, MAXIMIZED_VERT,
and MAXIMIZED_BOTH.
getOldState
public int getOldState()
Returns the state of this window before the event. This is the bitwise
or of fields in Frame: NORMAL, ICONIFIED, MAXIMIZED_HORIZ, MAXIMIZED_VERT,
and MAXIMIZED_BOTH.
getOppositeWindow
public Window getOppositeWindow()
Returns the opposite window if this window was involved in an activation
or focus change. For WINDOW_ACTIVATED and WINDOW_GAINED_FOCUS events,
this is the window that lost focus; for WINDOW_DEACTIVATED and
WINDOW_LOST_FOCUS, this is the window that stole focus; and for other
events (or when native implementation does not have the data available),
this is null.
- the opposite window, or null
getWindow
public Window getWindow()
Returns the event source as a Window
. If the source has
subsequently been modified to a non-Window, this returns null.
- the event source as a
Window
