/*
 * FILE:
 * quickfillcell.h
 *
 * FUNCTION:
 * The QuickFillCell implements a text cell with quick-fill
 * capabilities.  By "quick fill" we mean a cell that will
 * automatically sentence-complete the entry after the user
 * typed a sufficient number of letters to identify a unique
 * entry.
 *
 * On the output side, this is just a plain text cell.
 *
 * METHODS:
 * The xaccSetQuickFillCellValue() method sets the
 * current cell value to the indicated string,
 * simultaneously adding the string to the quick-fill
 * tree.
