focused</H3>
<PRE>
       <A HREF="../../widsets/api/Component.html" title="class in ">Component</A> <B>focused</B>()</PRE>
<DL>
<DD>Returns the currently focused component on shell.
 Only single component on component tree
 can receive focus.

<A NAME="computeLayout()"><!-- --></A><H3>
computeLayout</H3>
<PRE>
       void <B>computeLayout</B>()</PRE>
<DL>
<DD>Computes the actual position and dimensions of 
 every component on the screen. Layout computation 
 occurs automatically prior the Shell 
 is painted to screen. 
 
 <p>Sometimes it is necessary to know
 the position or dimensions of Components before the 
 Shell is made visible and this method is provided
 to serve that purpose. 

 Computation is potentionally a slow 
 operation and it should only be done when 
 absolutely necessary.

<A NAME="updateMenu()"><!-- --></A><H3>
updateMenu</H3>
<PRE>
       void <B>updateMenu</B>()</PRE>
<DL>
<DD>Updates <code>SOFTKEY_OK</code>, <code>SOFTKEY_MIDDLE</code>
 and <code>SOFTKEY_BACK</code>
 assosiations. The <A HREF="../../widsets/api/Script.html#getSoftKey(Shell, Component, int)"><CODE>Script.getSoftKey(Shell, Component, int)</CODE></A> callback is used
 to obtain the MenuItems.

 <p>This method does not call the <A HREF="../../widsets/api/API.html#flushScreen(boolean)"><CODE>flushScreen(boolean)</CODE></A>
 automatically so it might be necessary to call 
 that function as well.</p>

 <p>Key associations are assigned when 
 Shell is pushed on screen, but this method
 is provided in case the they need 
 to be changed on the fly.</p>
