<A NAME="nextTabStop(float, int)"><!-- --></A><H3>
nextTabStop</H3>
<PRE>
public float <B>nextTabStop</B>(float&nbsp;x,
                         int&nbsp;tabOffset)</PRE>
<DL>
<DD>Returns the next tab stop position given a reference position.
 This view implements the tab coordinate system, and calls
 <code>getTabbedSpan</code> on the logical children in the process 
 of layout to determine the desired span of the children.  The
 logical children can delegate their tab expansion upward to
 the paragraph which knows how to expand tabs. 
 <code>LabelView</code> is an example of a view that delegates
 its tab expansion needs upward to the paragraph.
 <p>
 This is implemented to try and locate a <code>TabSet</code>
 in the paragraph element's attribute set.  If one can be
 found, its settings will be used, otherwise a default expansion
 will be provided.  The base location for for tab expansion
 is the left inset from the paragraphs most recent allocation
 (which is what the layout of the children is based upon).<DD><DL>
