// Buttons can display a label, an icon, or both.

// attribute. It can be hidden via showLabel=false.
// example:
// | <button dojoType="dijit.form.Button" onClick="...">Hello world</button>
//
// example:
// | var button1 = new dijit.form.Button({label: "hello world", onClick: foo});
// | dojo.body().appendChild(button1.domNode);
// label: HTML String
// Text to display in button.
// If the label is hidden (showLabel=false) then and no title has
// been specified, then label is also set as title attribute of icon.

// will still be displayed, since the icon doesn't appear.
