/**
 * Shows a label, a disabled text box, and a button.
 * 
 * Label:
 *  - Right click: define the number of pages to scan and double-sided scanning.
 *     - Number of pages: it's the number of sides, not the number of sheets.
 *     - Backface: if an automatic document feeder is used. If 5 pages are to be
 *       scanned, feed 3 pages on front face, turn the whole stack including the
 *       6th page to scan the backfaces; the last page will be discarded.
 *       With a feeder, the 'double-sided' option can be off if all backfaces
 *       are blank.
 *       With a flatbed scanner, the 'double-sided' should typically be off and
 *       the pages scanned in their logical order.
 * 
 * Text box:
 *  - shows the path and the basename of the files to create. This must be set
 *    by the application in any convenient manner.
 *    Pressing the backspace key clears the text box.
 * 
 * Button:
 *  - Right click: shows the scanner widget.
 *  - Left click: starts or cancels scanning.
 *  - Ctrl + Right click: show the stamp widgets dialog.
