This is useful to keep the GUI event thread moving by not doing any layout on it. The layout is done on a granularity of operations on the child views. After each child view is accessed for some part of layout (a potentially time consuming operation) the remaining tasks can be abandoned or a new higher priority task (i.e. to service a synchronous request or a visible area) can be taken on. <p> While the child view is being accessed a read lock is aquired on the associated document so that the model is stable while being accessed.<P><DL><DT><B>Since: </B><DD>1.3</DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><A NAME="inner_class_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0"
