The default layout for a window is <code>BorderLayout</code>. <p> A window must have either a frame, dialog, or another window defined as its owner when it's constructed. <p> In a multi-screen environment, you can create a <code>Window</code> on a different screen device by constructing the <code>Window</code> with <A HREF="../../java/awt/Window.html#Window(java.awt.Window, java.awt.GraphicsConfiguration)"><CODE>Window(Window, GraphicsConfiguration)</CODE></A>. The <code>GraphicsConfiguration</code> object is one of the <code>GraphicsConfiguration</code> objects of the target screen device. <p> In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of all configurations are relative to the virtual device coordinate system. The origin of the virtual-coordinate system is at the upper left-hand corner of the primary physical screen. Depending on the location of the primary screen in the virtual device, negative coordinates are possible, as shown in the following figure. <p> <img src="doc-files/MultiScreen.gif" ALIGN=center HSPACE=10 VSPACE=7> <p> In such an environment, when calling <code>setLocation</code>, you must pass a virtual coordinate to this method. Similarly, calling <code>getLocationOnScreen</code> on a <code>Window</code> returns virtual device coordinates. Call the <code>getBounds</code> method of a <code>GraphicsConfiguration</code> to find its origin in the virtual coordinate system. <p> The following code sets the location of a <code>Window</code> at (10, 10) relative to the origin of the physical screen of the corresponding <code>GraphicsConfiguration</code>. If the bounds of the <code>GraphicsConfiguration</code> is not taken into account, the <code>Window</code> location would be set at (10, 10) relative to the virtual-coordinate system and would appear on the primary physical screen, which might be different from the physical screen of the specified <code>GraphicsConfiguration</code>. <pre> Window w = new Window(Window owner, GraphicsConfiguration gc); Rectangle bounds = gc.getBounds(); w.setLocation(10 + bounds.x, 10 + bounds.y); </pre> <p> Windows are capable of generating the following window events: WindowOpened, WindowClosed.<P><DL><DT><B>Since: </B><DD>JDK1.0</DD><DT><B>See Also: </B><DD><A HREF="../../java/awt/event/WindowEvent.html"><CODE>WindowEvent</CODE></A>, <A HREF="../../java/awt/Window.html#addWindowListener(java.awt.event.WindowListener)"><CODE>addWindowListener(java.awt.event.WindowListener)</CODE></A>, <A HREF="../../java/awt/BorderLayout.html"><CODE>BorderLayout</CODE></A>, <A HREF="../../serialized-form.html#java.awt.Window">Serialized Form</A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><A NAME="inner_class_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Inner Class Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected class</CODE></FONT></TD><TD><CODE><B><A HREF="../../java/awt/Window.AccessibleAWTWindow.html">Window.AccessibleAWTWindow</A></B></CODE><BR> This class implements accessibility support for the <code>Window</code> class.</TD></TR></TABLE> <A NAME="inner_classes_inherited_from_class_java.awt.Container"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Inner classes inherited from class java.awt.<A HREF="../../java/awt/Container.html">Container</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/Container.AccessibleAWTContainer.html">Container.AccessibleAWTContainer</A></CODE></TD></TR></TABLE> <A NAME="inner_classes_inherited_from_class_java.awt.Component"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Inner classes inherited from class java.awt.<A HREF="../../java/awt/Component.html">Component</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/Component.AccessibleAWTComponent.html">Component.AccessibleAWTComponent</A></CODE></TD></TR></TABLE> <!-- =========== FIELD SUMMARY =========== --><A NAME="fields_inherited_from_class_java.awt.Component"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class java.awt.<A HREF="../../java/awt/Component.html">Component</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/Component.html#BOTTOM_ALIGNMENT">BOTTOM_ALIGNMENT</A>, <A HREF="../../java/awt/Component.html#CENTER_ALIGNMENT">CENTER_ALIGNMENT</A>, <A HREF="../../java/awt/Component.html#LEFT_ALIGNMENT">LEFT_ALIGNMENT</A>, <A HREF="../../java/awt/Component.html#RIGHT_ALIGNMENT">RIGHT_ALIGNMENT</A>, <A HREF="../../java/awt/Component.html#TOP_ALIGNMENT">TOP_ALIGNMENT</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_java.awt.image.ImageObserver"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface java.awt.image.<A HREF="../../java/awt/image/ImageObserver.html">ImageObserver</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/image/ImageObserver.html#ABORT">ABORT</A>, <A HREF="../../java/awt/image/ImageObserver.html#ALLBITS">ALLBITS</A>, <A HREF="../../java/awt/image/ImageObserver.html#ERROR">ERROR</A>, <A HREF="../../java/awt/image/ImageObserver.html#FRAMEBITS">FRAMEBITS</A>, <A HREF="../../java/awt/image/ImageObserver.html#HEIGHT">HEIGHT</A>, <A HREF="../../java/awt/image/ImageObserver.html#PROPERTIES">PROPERTIES</A>, <A HREF="../../java/awt/image/ImageObserver.html#SOMEBITS">SOMEBITS</A>, <A HREF="../../java/awt/image/ImageObserver.html#WIDTH">WIDTH</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../java/awt/Window.html#Window(java.awt.Frame)">Window</A></B>(<A HREF="../../java/awt/Frame.html">Frame</A> owner)</CODE><BR> Constructs a new invisible window with the specified Frame as its owner.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../java/awt/Window.html#Window(java.awt.Window)">Window</A></B>(<A HREF="../../java/awt/Window.html">Window</A> owner)</CODE><BR> Constructs a new invisible window with the specified Window as its owner.</TD>⌨️ 快捷键说明
