They look like dojo buttons. If they are, you can get html style tooltips by setting the title parameter.new Button({
label: 'My Button',
title: 'Click this button to do something cool',
iconClass: 'iconCool',
onClick: function () {
}
})
[HTML]<div data-dojo-type="dijit/form/Button" data-dojo-props="label: 'My Button', title: 'Click this button to do something cool', iconClass: 'iconCool', onClick: function () { }"></div>[/HTML]
