eclipse中任务进度的使用

1.JFace中的进度条使用

import java.lang.reflect.InvocationTargetException;
import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.jface.dialogs.ProgressMonitorDialog;
import org.eclipse.jface.operation.IRunnableWithProgress;
import org.eclipse.swt.widgets.Shell;

public class OrdinaryProgress{
    private Shell shell;
    public OrdinaryProgress(Shell parent) {
       this.shell=shell;
    }
    
    public void run(){
	try {
	    new ProgressMonitorDialog(shell).run(true, true, new IRunnableWithProgress(){
	        public void run(IProgressMonitor monitor)
	    	    throws InvocationTargetException, InterruptedException {
	            monitor.beginTask("generate", 30);
	            for (int i = 0; i < 100; i++) {
			if(monitor.isCanceled())
			{
			     return ;
			}
			monitor.worked(1);
			Thread.sleep(50);
		    }
	            monitor.done();
	        }
	    });
	} catch (InvocationTargetException e) {
	} catch (InterruptedException e) {
	}
    }

    


}

2. 使用Eclipse提供的job

                Job searchJob = new Job("Task") {
                    protected IStatus run(IProgressMonitor monitor) {
                        try {
                            monitor.beginTask("", 100);

                            for (int i = 0; i < 10; i++) {
                                Thread.sleep(500);
                                monitor.worked(10);
                            }

                            monitor.done();
                        } catch (Exception e) {
                            e.printStackTrace();
                        }

                        return Status.OK_STATUS;
                    }
                };
                searchJob.setUser(true); // 是否需要弹出进度窗口
                searchJob.schedule();
