This method guarantees that after 0N/A * return no additional Java events will be generated, unless 0N/A * cause by user. Obviously, the method cannot be used on the 0N/A * event dispatch thread (EDT). In case it nevertheless gets 0N/A * invoked on this thread, the method throws the 0N/A * IllegalThreadException runtime exception. 0N/A * <p> This method allows to write tests without explicit timeouts 0N/A * or wait for some event. Example: 0N/A * f.setVisible(true); 0N/A * ((SunToolkit)Toolkit.getDefaultToolkit()).realSync(); 0N/A * <p> After realSync, <code>f</code> will be completely visible 0N/A * on the screen, its getLocationOnScreen will be returning the 0N/A * right result and it will be the focus owner. 0N/A * <p> Another example: 0N/A * ((SunToolkit)Toolkit.getDefaultToolkit()).realSync(); 0N/A * <p> After realSync, <code>b</code> will be focus owner. 0N/A * <p> Notice that realSync isn't guaranteed to work if recurring 0N/A * actions occur, such as if during processing of some event 0N/A * another request which may generate some events occurs. By 0N/A * default, sync tries to perform as much as {@value MAX_ITERS} 0N/A * cycles of event processing, allowing for roughly {@value 0N/A * MAX_ITERS} additional requests. 0N/A * <p> For example, requestFocus() generates native request, which 0N/A * generates one or two Java focus events, which then generate a 0N/A * serie of paint events, a serie of Java focus events, which then 0N/A * generate a serie of paint events which then are processed - 0N/A * three cycles, minimum. 0N/A * @param timeout the maximum time to wait in milliseconds, negative means "forever". 0N/A // Let's do sync first 0N/A // During the wait process, when we were processing incoming 0N/A // events, we could have made some new request, which can 0N/A // Therefore, we dispatch them as long as there is something 0N/A // native requests were dispatched by X/Window Manager or Windows 0N/A // Moreover, we processed them all on Toolkit thread 0N/A // Now wait while EDT processes them. 0N/A // During processing of some events (focus, for example), 0N/A // some other events could have been generated. So, after 0N/A // waitForIdle, we may end up with full EventQueue 0N/A // Again, for Java events, it was simple to check for new Java 0N/A // events by checking event queue, but what if Java events 0N/A // resulted in native requests? Therefor, check native events again. 0N/A * Platform toolkits need to implement this method to perform the 0N/A * sync of the native queue. The method should wait until native 0N/A * requests are processed, all native events are processed and 0N/A * corresponding Java events are generated. Should return 0N/A * <code>true</code> if some events were processed, 0N/A * <code>false</code> otherwise. 0N/A * Waits for the Java event queue to empty. Ensures that all 0N/A * events are processed (including paint events), and that if 0N/A * recursive events were generated, they are also processed. 0N/A * Should return <code>true</code> if more processing is 0N/A * necessary, <code>false</code> otherwise. 0N/A // Here we block EDT. It could have some 0N/A // events, it should have dispatched them by 0N/A // now. So native requests could have been 0N/A // generated. First, dispatch them.
