There can be many <code>GraphicsConfiguration</code> objects associated with a single graphics device. For example, on X11 windowing systems, each visual is a different <code>GraphicsConfiguration</code>. On PCs and Macintoshes, the different screen resolution/color resolution combinations would be different <code>GraphicsConfiguration</code> objects. <p> In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of the <code>GraphicsConfiguration</code> objects are relative to the virtual coordinate system. When setting the location of a component, use <A HREF="../../java/awt/GraphicsConfiguration.html#getBounds()"><CODE>getBounds</CODE></A> to get the bounds of the desired <code>GraphicsConfiguration</code> and offset the location with the coordinates of the <code>GraphicsConfiguration</code>, as the following code sample illustrates: <pre> Frame f = new Frame(GraphicsConfiguration gc); Rectangle bounds = gc.getBounds(); f.setLocation(10 + bounds.x, 10 + bounds.y); </pre> To determine if your environment is a virtual device environment, call <code>getBounds</code> on all of the <code>GraphicsConfiguration</code> objects in your system. If any of the origins of the returned bounds are not (0, 0), your environment is a virtual device environment. <p> You can also use <code>getBounds</code> to determine the bounds of the virtual device. Call <code>getBounds</code> on all of the <code>GraphicsConfiguration</code> objects in your system. Then, calculate the union of all of the bounds returned from the calls to <code>getBounds</code>. The union is the bounds of the virtual device. The following code sample calculates the bounds of the virtual device. <pre> Rectangle virtualBounds = new Rectangle(); GraphicsEnvironment ge = GraphicsEnvironment. getLocalGraphicsEnvironment(); GraphicsDevice[] gs = ge.getScreenDevices(); for (int j = 0; j < gs.length; j++) { GraphicsDevice gd = gs[j]; GraphicsConfiguration[] gc = gd.getConfigurations(); for (int i=0; i < gc.length; i++) { virtualBounds = virtualBounds.union(gc[i].getBounds()); } } </pre><P><DL><DT><B>See Also: </B><DD><A HREF="../../java/awt/Window.html"><CODE>Window</CODE></A>, <A
