Application doesn't support proportionality resolution

Application doesn't support proportionality resolution. ie, small resolution screen shows half of the application.
please anybody help me.....

Make a smaller application?

I think you should provide a code sample of what you're talking about. It's certainly possible to create a Vaadin UI that fits on a small screen. You can set explicit widths on all components so that they don't expand too much. I recommend not specifying sizes in pixels, but in 'em' units so that things line up well if users set lower/higher default text sizes in their browsers.

public class MyWindow extends Window  {

               public MyWindow() {
		        setContent(buildWindow());
	       }

	       private VerticalLayout buildWindow() {
		
	                VerticalLayout layout = new VerticalLayout();
		        layout.setSizeFull();
        
		        VerticalLayout windowLayout = new VerticalLayout();
		        windowLayout.setWidth("1000px");
		        windowLayout.setHeight("650px");
		
		        VerticalLayout centerPage = buildPage();
		       windowLayout.addComponent(centerPage);
		       windowLayout.setComponentAlignment(centerPage, Alignment.TOP_CENTER);
		
		       layout.addComponent(windowLayout);
		       layout.setComponentAlignment(windowLayout, Alignment.TOP_CENTER);
		
		       return layout;
                }
	}

Here, I reduce the size of browser (width and height) the windowLayout's content not fully display or/and didn't present vertical or horizontal scrollbar.
I wants any resolution the display actual size of windowLayout and align in top center of the window.

Please help me.....

Replace

windowLayout.setWidth("1000px");
windowLayout.setHeight("650px");

With

windowLayout.setWidth("100%");
windowLayout.setHeight("100%");

Or

windowLayout.setSizeFull();

To let the layout use all available space and not force it to 1000px per 650px
