All known Subclasses: java.awt.Frame, java.awt.Dialog,
| Window | | public class Window extends Container (Code) | | A Window object is a top-level window with no borders and no
menubar. It could be used to implement a pop-up menu.
The default layout for a window is BorderLayout.
A Window object blocks input to other application
windows when it is shown.
Windows are capable of generating the following window events:
WindowOpened, WindowClosed.
Compatibility
The direct creation of Window objects is an optional feature
in PersonalJava and Personal Profile implementations. If the
implementation prohibits the direct creation of Window objects,
the constructor throws and UnsupportedOperationException.
System Properties
java.awt.SupportsWindow is set to "true"
or "false" indicating if the platform supports direct creation
of window objects.

| Constructor Summary | |
| | Window()
| | public | Window(Frame parent)
Constructs a new invisible window.
The window is not initially visible. |
| OPENED | | final static int OPENED(Code) | | |
| addWindowListener | | public synchronized void addWindowListener(WindowListener l)(Code) | | Adds the specified window listener to receive window events from
this window.
Parameters:
l - the window listener |
| constructComponentName | | String constructComponentName()(Code) | | Construct a name for this component. Called by getName() when the
name is null.
|
| dispose | | public void dispose()(Code) | | Disposes of this window. This method must
be called to release the resources that
are used for the window.
since:
JDK1.0 |
| getFocusOwner | | public Component getFocusOwner()(Code) | | Returns the child component of this Window which has focus if and
only if this Window is active.
the component with focus, or null if no children have focusassigned to them. |
| getGraphics | | public Graphics getGraphics()(Code) | | Creates a graphics context for this component. This method will
return null if this component is currently not on
the screen.
A graphics context for this component, or nullif it has none.
See Also: java.awt.Component.paint
since:
JDK1.0 |
| getInputContext | | synchronized InputContext getInputContext()(Code) | | Gets the input context for this window. A window always has an input context,
which is shared by subcomponents unless they create and set their own.
See Also: Component.getInputContext |
| getLocale | | public Locale getLocale()(Code) | | Gets the Locale object that is associated
with this window, if the locale has been set.
If no locale has been set, then the default locale
is returned.
the locale that is set for this window.
See Also: java.util.Locale
since:
JDK1.1 |
| getWarningString | | final public String getWarningString()(Code) | | Gets the warning string that is displayed with this window.
If this window is insecure, the warning string is displayed
somewhere in the visible area of the window. A window is
insecure if there is a security manager, and the security
manager's checkTopLevelWindow method returns
false when this window is passed to it as an
argument.
If the window is secure, then getWarningString
returns null. If the window is insecure, this
method checks for the system property
awt.appletWarning
and returns the string value of that property.
the warning string for this window.

| isActive | | boolean isActive()(Code) | | |
| isLightweightWhenDisplayable | | boolean isLightweightWhenDisplayable()(Code) | | |
| pack | | public void pack()(Code) | | Causes subcomponents of this window to be laid out at their
preferred size.
since:
JDK1.0 |
| postWindowEvent | | synchronized void postWindowEvent(int id)(Code) | | |
| processEvent | | protected void processEvent(AWTEvent e)(Code) | | Processes events on this window. If the event is an WindowEvent,
it invokes the processWindowEvent method, else it invokes its
superclass's processEvent.
Parameters:
e - the event |
| processWindowEvent | | protected void processWindowEvent(WindowEvent e)(Code) | | Processes window events occurring on this window by
dispatching them to any registered WindowListener objects.
NOTE: This method will not be called unless window events
are enabled for this component; this happens when one of the
following occurs:
a) A WindowListener object is registered via addWindowListener()
b) Window events are enabled via enableEvents()
See Also: Component.enableEvents
Parameters:
e - the window event |
| removeWindowListener | | public synchronized void removeWindowListener(WindowListener l)(Code) | | Removes the specified window listener so that it no longer
receives window events from this window.
Parameters:
l - the window listener |
| repaint | | public void repaint(long tm, int x, int y, int width, int height)(Code) | | |
| setCursor | | public synchronized void setCursor(Cursor cursor)(Code) | | Set the cursor image to a predefined cursor.
cursor One of the constants definedby the Cursor class. If this parameter is nullthen the cursor for this window will be set to the typeCursor.DEFAULT_CURSOR .

since:
JDK1.1 |
| show | | public void show()(Code) | | Shows this window, and brings it to the front.
If this window is not yet visible, show
makes it visible. If this window is already visible,
then this method brings it to the front.
See Also: java.awt.Window.toFront
See Also: java.awt.Component.setVisible
since:
JDK1.0 |
| toBack | | public void toBack()(Code) | | Sends this window to the back.
Places this window at the bottom of the stacking order and
makes the corresponding adjustment to other visible windows.
See Also: java.awt.Window.toFront
since:
JDK1.0 |
| toFront | | public void toFront()(Code) | | Brings this window to the front.
Places this window at the top of the stacking order and
shows it in front of any other windows.
