Detailed Description

specifies how to update UGroup, UBox, UWin objects and subclasses.

This object is given as an argument of UGroup::update() Examples:

       box.update(UUpdate::paint);   // repaints the box
       box.update(UUpdate::all);     // updates box layout then repaints
       box.update();                 // same as: box.update(UUpdate::all);
 </pe>
 Notes:

by default, no update is performed is the object is not shown
    (see: UCtrl::isShown()). This can be changed by calling the 
    layoutIfNotShown() method:
 
       UUpdate upd = UUpdate::all;   // layout and paint
       upd.evenIfNotShown();
       box.update(upd);
 

the paintDoubleBuffered() method requests double buffering painting: 
       UUpdate upd = UUpdate::paint; // just paint
       upd.setDoubleBuffering();
       box.update(upd);
 
other UUpdate methods are related to the internal implementation.
