public class IlvJScrollGanttSheet extends JComponent implements IlvTimeScrollable, IlvVerticalScrollable
IlvJScrollGanttSheet
is a user interface component
that consists of an IlvGanttTimeScale
positioned above an
IlvGanttSheet
. By default, an IlvTimeScrollBar
is
placed along the bottom and a vertical scroll bar is placed against the
right margin.
The IlvJScrollGanttSheet
class implements both the
IlvTimeScrollable
and IlvVerticalScrollable
interfaces.
A Gantt configuration
is used to
coordinate the horizontal scrolling of the time scale, the Gantt sheet,
and the time scroll bar and the vertical scrolling of the Gantt sheet
and the vertical scroll bar. The Gantt configuration can be provided
when the sheet is constructed or by calling the
setGanttConfiguration(ilog.views.gantt.IlvGanttConfiguration)
method. However, it is important
to note that the scrollable APIs cannot be used until the
sheet is provided with a configuration.
Two horizontal 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 sheet enforces this relationship by correcting or trimming properties in the following way:
setMinVisibleTime(java.util.Date)
and setMaxVisibleTime(java.util.Date)
methods first validate that:
minVisibleTime <= maxVisibleTime
If not, an IllegalArgumentException
is thrown.
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 sheet uses the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeInterval, java.util.Date, java.util.Date, ilog.views.gantt.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
.
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 sheet use the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeInterval, java.util.Date, java.util.Date, ilog.views.gantt.IlvDuration)
method to
perform validation and trimming of the time value arguments.
