- - ### Constructor Detail

    - #### ButtonBase

          protected ButtonBase(Element elem)

      Creates a new ButtonBase that wraps the given browser element.
      Parameters:
        `elem` - the DOM element to be wrapped

  - ### Method Detail

    - #### getHTML

          public java.lang.String getHTML()

      Description copied from interface: `HasHTML`
      Gets this object's contents as HTML.
      Specified by:
        `getHTML` in interface `HasHTML`
      Returns:
        the object's HTML

    - #### getText

          public java.lang.String getText()

      Description copied from interface: `HasText`
      Gets this object's text.
      Specified by:
        `getText` in interface `HasText`
      Returns:
        the object's text

    - #### setHTML

          public void setHTML(java.lang.String html)

      Description copied from interface: `HasHTML`
      Sets this object's contents via HTML. Use care when setting an object's HTML; it is an easy way to expose script-based security problems. Consider using `HasText.setText(String)` whenever possible.
      Specified by:
        `setHTML` in interface `HasHTML`
      Parameters:
        `html` - the object's new HTML

    - #### setHTML

          public void setHTML(SafeHtml html)

      Description copied from interface: `HasSafeHtml`
      Sets this object's contents via known-safe HTML.

      The object will behave exactly the same as when a widget's `HasHTML.setHTML(String)` method is invoked; however the `SafeHtml` passed to this method observes the contract that it can be used in an HTML context without causing unsafe script execution. Thus, unlike `HasHTML.setHTML(String)`, using this method cannot result in Cross-Site Scripting security vulnerabilities.

      Specified by:
        `setHTML` in interface `HasSafeHtml`
      Parameters:
        `html` - the object's new HTML, represented as a `SafeHtml` object

    - #### setText

          public void setText(java.lang.String text)

      Description copied from interface: `HasText`
      Sets this object's text.
      Specified by:
        `setText` in interface `HasText`
      Parameters:
        `text` - the object's new text
