How to align button e.g. in a panel?

Hello!

I got this problem. I've created a panel and in the header there are some buttons. The coding is:

     //Create a panel instance

        var oPanel = new sap.ui.commons.Panel({width: "350px"});

     //Settings of the panel

        oPanel.setTitle(new sap.ui.commons.Title({text: "This is the panel"}));

        oPanel.setHeight("76px");

        oPanel.setWidth("100%");

     //Add some buttons to the panel header

         oPanel.addButton(new sap.ui.commons.Button({text: 'Help'}));

How can I align the button to the right side of the panel header? If it's not possible, what are other possibilities?

Thanks in advance!
