H eadlines Demo

 The Headlines demonstration presents a simple panel set that implements a sophisticated looking "headline ticker" display. To jump to a page that would contain the detailed story for a headline, all that the user must do is click on the applet when the headline of interest is displayed.

Notes
  • Notice that the WVPanelTimer panel (named control) has a <WAIT id=fx> tag after each trigger that is sent to the WVPanelFx panel to begin a transition animation. This is used to ensure that the new headline is displayed at least three full seconds after each transition animation completes. The way this works is that the WVPanelFx panel has specified the attribute "notify=control." Since pre-rendering is being performed for the transition animations (preRender=true), the notify attribute is used to send a trigger to the WVPanelTimer panel whenever a transition animation completes. The WVPanelTimer panel <WAIT>s until it receives this trigger, then immediately begins a three second delay.
