7 * This is a @b digital clock widget. In its default theme, it has a
8 * vintage "flipping numbers clock" appearance, which will animate
9 * sheets of individual algarisms individually as time goes by.
11 * A newly created clock will fetch system's time (already
12 * considering local time adjustments) to start with, and will tick
13 * accondingly. It may or may not show seconds.
15 * Clocks have an @b edition mode. When in it, the sheets will
16 * display extra arrow indications on the top and bottom and the
17 * user may click on them to raise or lower the time values. After
18 * it's told to exit edition mode, it will keep ticking with that
19 * new time set (it keeps the difference from local time).
21 * Also, when under edition mode, user clicks on the cited arrows
22 * which are @b held for some time will make the clock to flip the
23 * sheet, thus editing the time, continuosly and automatically for
24 * the user. The interval between sheet flips will keep growing in
25 * time, so that it helps the user to reach a time which is distant
28 * The time display is, by default, in military mode (24h), but an
29 * am/pm indicator may be optionally shown, too, when it will
32 * Smart callbacks one can register to:
33 * - "changed" - the clock's user changed the time
35 * Here is an example on its usage:
36 * @li @ref clock_example
45 * Identifiers for which clock digits should be editable, when a
46 * clock widget is in edition mode. Values may be ORed together to
47 * make a mask, naturally.
