<P> The hour scale has more builtin formatting possibilities. The
|
|
|
30 |
following formatting options are available</P>
|
|

<OL>
|
|
|
32 |
<LI> "HOURSTYLE_HM24", Will display the only the hour in military time
|
|
|
33 |
0-24 , for example 13:00</LI>
|
|
|
34 |
<LI> "HOURSTYLE_H24", Will display the hour with both hour and minute in
|
|
|
35 |
military time 0-24, for example 13</LI>
|
|
|
36 |
<LI>"HOURSTYLE_HMAMPM", Will display the hour and minutes with a
|
|
|
37 |
suitable am/pm postfix, for example 1:30pm</LI>
|
|
|
38 |
<LI> "HOURSTYLE_HAMPM", Will display only the hour with a suitable am/pm
|
|
|
39 |
postfix, for example 1pm</LI>
|
|
|
40 |
<LI>"HOURSTYLE_CUSTOM", Custom defined format as specified with a call
|
|
|
41 |
to HeaderProperty::SetFormatString()</LI>
|
|
|
42 |
</OL>
|
|
|
43 |
<P> For hours it is possible to specify the interval in either of two
|
|
|
44 |
ways. With an integer, e.g. 6, or as time interval, e.g. "1:30" which
|
|
|
45 |
makes the interval one and a half hour. The only restriction is that
|
|
|
46 |
the interval must be even dividable for 24 hours since one day is the
|
|
|
47 |
smallest possible interval to show. This means that it is allowed to
|
|
|
48 |
use, for example 2,4,6,"1:30" or "0:45" as intervals but not 7, "2:45".</P>
