});示例3: createButtonNode
/**
* Create a button node for the dialog.
*
* @param button - The button data.
*
* @returns A node for the button.
*/

let className = this.createItemClass(button);
// We use realize here instead of creating
// nodes with document.createElement as a
// shorthand, and only because this is not
// called often.
return VirtualDOM.realize(
h.button({ className },
this.renderIcon(button),
this.renderLabel(button))
);

/**
* Create the header of the dialog.
*
* @param title - The title of the dialog.
*
* @returns A widget for the dialog header.
