This behavior includes, but is not 0N/A * <li>Scrolling to a specified position. 0N/A * <br>For example, calling <code>ScrollPane.setScrollPosition</code> 0N/A * and then <code>getScrollPosition</code> may return an incorrect 0N/A * value if the original request has not yet been processed. 0N/A * <li>Moving the focus from one component to another. 0N/A * <br>For more information, see 0N/A * Focus Transfers</a>, a section in 0N/A * <li>Making a top-level container visible. 0N/A * <br>Calling <code>setVisible(true)</code> on a <code>Window</code>, 0N/A * <code>Frame</code> or <code>Dialog</code> may occur 0N/A * <li>Setting the size or location of a top-level container. 0N/A * <br>Calls to <code>setSize</code>, <code>setBounds</code> or 0N/A * <code>setLocation</code> on a <code>Window</code>, 0N/A * <code>Frame</code> or <code>Dialog</code> are forwarded 0N/A * to the underlying window management system and may be 0N/A * ignored or modified.
