    • doClickStateUpdate

      protected boolean doClickStateUpdate(boolean shiftKey, boolean ctrlKey) throws IOException
      Override of default clickAction that makes this radio button the selected one when it is clicked. This method implements the control state update part of the click action.

      The default implementation only calls doClickStateUpdate on parent's DomElement (if any). Subclasses requiring different behavior (like HtmlSubmitInput) will override this method.

      Overrides:
      doClickStateUpdate in class DomElement
      Parameters:
      shiftKey - true if SHIFT is pressed
      ctrlKey - true if CTRL is pressed
      Returns:
      true if doClickFireEvent method has to be called later on (to signal, that the value was changed)
      Throws:
      IOException - if an IO error occurred

    • setCheckedForPage

      private void setCheckedForPage(HtmlPage htmlPage)
      Select the specified radio button in the page (outside any <form>).

    • doClickFireChangeEvent

      This method implements the control onchange handler call during the click action.
      Overrides:
      doClickFireChangeEvent in class DomElement

    • preventDefault

      protected void preventDefault()
      This method is called if the current fired event is canceled by preventDefault().

      The default implementation does nothing.

      Overrides:
      preventDefault in class DomElement

    • setDefaultValue

      public void setDefaultValue(String defaultValue)
      Sets the default value to use when this element gets reset, if applicable. Also sets the value to the new default value.

    • setDefaultChecked

      public void setDefaultChecked(boolean defaultChecked)
