      • doClickStateUpdate

        protected boolean doClickStateUpdate​(boolean shiftKey,
                                     boolean ctrlKey)
                              throws java.io.IOException
        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:
        java.io.IOException - if an IO error occurs
