今天讲一讲Apache Pivot中的ProgressBar中的一种，Meter

package meter_java;
    
    import org.apache.pivot.wtk.*;
    import org.apache.pivot.collections.*;
    
    public class meter_java implements Application
    {
        
    	private Window window=null;
    	public static void main(String [] args)
    	{
        
    		try
    		{
        
    			DesktopApplicationContext.main(meter_java.class, args);
    		}
    		catch(Throwable err)
    		{
        
    		}
    	}
    	@Override
    	public void startup(Display display, Map<String, String>properties)
    	{
        
    		window=new Window();
    		BoxPane panel=new BoxPane();
    		Meter meter1=new Meter();
    		meter1.setPreferredSize(500, 5);
    		meter1.setPercentage(0);
    		panel.add(meter1);
    		PushButton button1=new PushButton();
    		button1.getButtonPressListeners().add(new ButtonPressListener()
    				{
        
    			@Override
    			public void buttonPressed(Button button)
    			{
        
    				if(meter1.getPercentage()+0.1<=1)
    				{
        
    					meter1.setPercentage(meter1.getPercentage()+0.1);
    				}
    				else
    				{
        
    					meter1.setPercentage(0);
    				}
    			}
    				});
    		panel.add(button1);
    		window.setContent(panel);
    		window.setTitle("ProgressBar Meter");
    		window.setMaximized(true);
    		window.open(display);
    	}
    	@Override
    	public boolean shutdown(boolean optional)
    	{
        
    		if(window!=null)
    		{
        
    			window.close();
    		}
    		return false;
    	}
    	@Override
    	public void suspend()
    	{
        
    	}
    	@Override
