Try like this

You have to add the widgets after you set the align center

VerticalPanel vpnPanel = new VerticalPanel();
        vpnPanel.add(scrollPanel);   //all controls added to scrill panel with help of set widget 
        vpnPanel.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
        HorizontalPanel btnLayoutPanel = new HorizontalPanel();
        btnLayoutPanel.setSpacing(10);
        btnLayoutPanel.add(closeButton);
        vpnPanel.add(btnLayoutPanel);
        decPopuppanel.setWidget(vpnPanel);
