Direct Known Subclasses:

IlvGanttTimeScale

public class IlvTimeScale

extends JComponent

implements IlvTimeScrollable

The IlvTimeScale class is a time scale component that contains several IlvTimeScaleRow objects. Each row represents a particular time unit and is responsible for drawing itself. The rows are not true UI components, but behave like renderers.

To scroll through the scale or to zoom on it when changing the time value and the visible duration, a new IlvTimeConverter object must be set for the scale.

Default actions are provided on this object:

• Perform an integer zoom when the user double-clicks an interval.
• Perform a zoom by selecting two points (start and end points).
• Perform translation when the mouse is dragged on the scale.

You can disable these actions to provide your own ones through event listeners.

getCalendar

public Calendar getCalendar()

This method returns a Calendar object. By default, it returns the result of the method Calendar.getInstance() (default locale and default time zone). If a Locale or a TimeZone has been specified with one of the methods setLocale or setTimeZone, the method constructs the calendar with these values. When deriving the class IlvTimeScaleRow, you should use this method to get a Calendar object to compute or display time values. However, be careful, this method always returns the same Calendar object constructed in computeCalendar. Therefore, you should clone it if you need more than one Calendar objects.

See Also:

setLocale(java.util.Locale), setTimeZone(java.util.TimeZone), computeCalendar(), getCalendar(Date), IlvBasicTimeScaleRow.getDateFormat()

getCalendar

public Calendar getCalendar(Date time)

This utility method returns a Calendar object that points to the specified time. Be careful, this method always returns the same Calendar object constructed in computeCalendar. You should therefore clone it if you need more than one object.

Parameters:

time - The current day on the calendar.

See Also:

computeCalendar()

setTimeZone

public void setTimeZone(TimeZone timezone)

The time zone set with this method will be used instead of the default time zone. To revert to the default time zone, set the timezone argument to null.

Parameters:

timezone - The new time zone.

See Also:

getCalendar()

getTimeZone

public TimeZone getTimeZone()

This method returns the time zone of this scale.

setLocale

public void setLocale(Locale locale)

This method overrides the Component method to compute the new Calendar object attached to this scale.

Overrides:

setLocale in class Component

computeCalendar

public void computeCalendar()

This method is called when changing the locale or the time zone of this scale to compute the new calendar. If you change the locale or time zone at another level, you should call this method to compute new values.

getMinVisibleTime

public Date getMinVisibleTime()

Returns the minimum time that the scale can show in bounded scrolling mode.

Specified by:

getMinVisibleTime in interface IlvTimeScrollable

Returns:

The minimum visible time or null if the scale is in unbounded scrolling mode.

See Also:

setMinVisibleTime(java.util.Date)

setMinVisibleTime

public void setMinVisibleTime(Date min)

Sets the minimum time that the scale can show in bounded scrolling mode. The current visible time and duration are trimmed to fit the new min-max interval by calling the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeScrollable, ilog.views.gantt.IlvTimeInterval) method. A minVisibleTimeChanged event is then fired to all registered listeners. If min > maxVisibleTime an IllegalArgumentException will be thrown.

Specified by:

setMinVisibleTime in interface IlvTimeScrollable

Parameters:

min - The minimum visible time or null to set the scale to unbounded scrolling mode.

See Also:

getMinVisibleTime()

getMaxVisibleTime

public Date getMaxVisibleTime()

Returns the maximum time that the scale can show in bounded scrolling mode.

Specified by:

getMaxVisibleTime in interface IlvTimeScrollable

Returns:

The maximum visible time or null if the scale is in unbounded scrolling mode.

See Also:

setMaxVisibleTime(java.util.Date)

setMaxVisibleTime

public void setMaxVisibleTime(Date max)

Sets the maximum time that the scale can show in bounded scrolling mode. The current visible time and duration are trimmed to fit the new min-max interval by calling the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeScrollable, ilog.views.gantt.IlvTimeInterval) method. A maxVisibleTimeChanged event is then fired to all registered listeners. If max < minVisibleTime an IllegalArgumentException will be thrown.

Specified by:

setMaxVisibleTime in interface IlvTimeScrollable

Parameters:

max - The maximum visible time or null to set the scale to unbounded scrolling mode.

See Also:

getMaxVisibleTime()

getVisibleTime

public Date getVisibleTime()

Returns the beginning of the time interval displayed by the scale.

Specified by:

getVisibleTime in interface IlvTimeScrollable

See Also:

setVisibleTime(java.util.Date)

setVisibleTime

public void setVisibleTime(Date time)

Sets the beginning of the time interval displayed by the scale. The specified time value is compared against the min and max visible times and is trimmed if necessary by calling the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeScrollable, ilog.views.gantt.IlvTimeInterval) method. The time scale then adjusts its internal zoom and scroll parameters so that the specified time value is drawn at the beginning of the time scale. A VisibleTimeChangedEvent is then fired to all registered listeners. If you are changing both the visible time and duration, it is preferable to use the setVisibleInterval(java.util.Date, ilog.views.gantt.IlvDuration) method instead.

Specified by:

setVisibleTime in interface IlvTimeScrollable

Parameters:

time - The new time value.

See Also:

getVisibleTime()

getVisibleDuration

public IlvDuration getVisibleDuration()

Returns the duration of the time interval displayed by the scale.

See Also:

setVisibleDuration(ilog.views.gantt.IlvDuration)

setVisibleDuration

public void setVisibleDuration(IlvDuration duration)

Sets the duration of the time interval displayed by the scale. The specified duration is compared against the min and max visible times and is trimmed if necessary by calling the IlvTimeScrollUtil.trimInterval(ilog.views.gantt.IlvTimeScrollable, ilog.views.gantt.IlvTimeInterval) method. The time scale then adjusts its internal zoom and scroll parameters so that the specified duration is visible. A VisibleDurationChangedEvent is then fired to all registered listeners. If you are changing both the visible time and duration, it is preferable to use the setVisibleInterval(java.util.Date, ilog.views.gantt.IlvDuration) method instead.

Specified by:

setVisibleDuration in interface IlvTimeScrollable

Parameters:

duration - The new duration value.
