The marking concept is that there exists different time units of
each time-line. If there is any smallest time unit, which is marked
for recording, then the time unit for each time-line that contains
the time will be marked.
Example:
In an Hour time-line, 1:10~1:15(include lower bound, exclude upper
bound) is marked, although only in 1:10~1:15 the recording is valid.
As situation of point 1, in Day time-line, 1:00~1:20(include lower bound,
exclude upper bound) is marked, although only in 1:10~1:15 the recording
is valid.
As situation of point 1, in Week time-line, 1:00~2:00 (include lower bound,
exclude upper bound) is marked, although only in 1:10~1:15 the recording
is valid.
As situation of point 1, in Month time-line, 00:00~12:00 (include lower
bound, exclude upper bound) is marked, although only in 1:10~1:15 the
recording is valid.
Using Mouse buttons in the Scheduler
The scheduler tool is designed for a two-button mouse. In this manual, we use
left mouse button and right mouse button to distinguish them.
When you click or double click the left mouse button over the time-line, the
time-line will mark the time for the scheme of the schedule; if you click or double
click the right mouse button over the time-line, the time-line will unmark (clear)
the record in the schedule.
Operations over time-lines which are left mouse button based are designed for
marking the time (make a recording, red bars on time-line) in the schedule.
The operations which are right mouse button based are designed for cancelling
the recording (unmark the time, green bars on time-line) in the schedule.
