public class IlvTimeScrollBar extends JScrollBar implements IlvTimeScrollable
IlvTimeScrollbar is a scroll bar that implements the
IlvTimeScrollable interface and is designed to scroll over a
time period. The scroll bar is used in an IlvJScrollGanttSheet
to scroll the
IlvGanttSheet. Two time
scrolling modes are supported:
minimum visible time and the
maximum visible time. Both values must be
valid and non-null.
In bounded scrolling mode there are four interrelated time properties: minVisibleTime, maxVisibleTime, visibleTime, and visibleDuration. These four values define two nested ranges like this:
minVisibleTime <= visibleTime <= visibleTime + visibleDuration <= maxVisibleTime
The scroll bar enforces this relationship by correcting or trimming properties according to the following rules:
setMinVisibleTime(java.util.Date) and setMaxVisibleTime(java.util.Date)
methods first validate that:
minVisibleTime <= maxVisibleTime
If not, an IllegalArgumentException is thrown. Next, the
visible time and visible duration properties may be trimmed (in that
order) to fit within the new min-max interval.
setVisibleTime(java.util.Date) and setVisibleDuration(ilog.views.gantt.IlvDuration) methods
trim their argument to fit within the limits defined by the other three
properties. For example if
maxVisibleTime.equals(visibleTime.add(IlvDuration.ONE_DAY)),
then setVisibleDuration(IlvDuration.ONE_WEEK) would
change the duration to IlvDuration.ONE_DAY.
The scroll bar uses the
IlvTimeScrollUtil.trimInterval(IlvTimeScrollable, Date, IlvDuration)
method to perform consistent validation and trimming of the time value
arguments.
minimum visible time and the
maximum visible time are undefined and are
set to null. The scroll bar can scroll to the left or to
the right normally, but the slider always snaps back to the center and
its size never changes.
Even in unbounded scrolling mode, there is an inherent limitation on the
minimum and
maximum times that can be
scrolled to. As in bounded scrolling mode, this is enforced by having
the scroll bar use the
IlvTimeScrollUtil.trimInterval(IlvTimeScrollable, Date, IlvDuration)
method to perform validation and trimming of the time value arguments.
