public class LwAdvViewMan
extends LwViewMan

The class extends the basic view manager functionality. It provides ability to bind a view with a given name. The view manager can be used to change standard view faces for some lightweight components. For example, for LwButton component using the view manager it is possible to re-bind "bt.off" and "bt.on" face views to some custom views, by put method of the view manager. The sample below illustrates the usage: 

   ...
   LwButton button = new LwButton("Ok");
   LwAdvViewMan man = new LwAdvViewMan();
   man.put("bt.off", LwImgRender("off.gif"));
   man.put("bt.on", LwImgRender("on.gif"));
   button.setViewMan(man);
   ...
In the sample above the "off.gif" image will be used when the button is un-pressed and the "on.gif" image when the button is pressed.
