RCP学习:Splash状态栏

今天遇到个问题,Eclipse在Splash启动阶段对多线程的支持有点不同。根据某人的见解,org.eclipse.ui.internal.StartupThreading 可以解决这个问题

 
我看了一眼Eclipse自己的Splash实现是这样的:
 
    private void updateUI(final Runnable r) {
        Shell splashShell = getSplash();
        if (splashShell == null || splashShell.isDisposed())
            return;
        
        Display display = splashShell.getDisplay();
        
        if (Thread.currentThread() == display.getThread())
            r.run(); // run immediatley if we're on the UI thread
        else {
            // wrapper with a StartupRunnable to ensure that it will run before
            // the UI is fully initialized
            StartupRunnable startupRunnable = new StartupRunnable() {

                public void runWithException() throws Throwable {
                    r.run();
                }
            };
            display.asyncExec(startupRunnable);
        }
    }

 

Eclipse建议的状态监控,是用IProgressMonitor来解决,使用方式是重写
org.eclipse.ui.splash.AbstractSplashHandler.getBundleProgressMonitor()这个方法。
 
然后提供一个IProgressMonitor,参考org.eclipse.jface.wizard.ProgressMonitorPart。
