```
public class IlvTimeScale
extends JComponent
implements IlvTimeScrollable
```
IlvTimeScale 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.
The default actions provided on this object are that it will:
- Performs an integer zoom when the user double-clicks an interval.
- Performs a zoom by selecting two points (start and end points).
- Performs translation when the mouse is dragged on the scale.
You can disable these actions to provide your own ones using event listeners.
To adjust the time scale rows visibility whenever the visible time interval of the time scale changes, a new IlvTimeScaleVisibilityPolicy object must be set for the scale. The default implementation does not set this visibility policy, and the visibility of the rows is based on their visible property. This means that users of this class must control row visibility using the hideRow(ilog.views.gantt.scale.IlvTimeScaleRow) and the showRow(ilog.views.gantt.scale.IlvTimeScaleRow) methods. Use this class to define a time scale using cascading style sheets (CSS).

public void setVisibilityPolicy(IlvTimeScaleVisibilityPolicy policy)
```
    Sets the visibility policy of the time scale, and adjusts the rows if needed.
    A visibility policy determines which rows are visible when the time scale visible time interval changed.
    
    Parameters:
    
    policy - The visibility policy. If the policy is set to the default value of null, row visibility is based on their visible property. If the policy is not null, the visibility of the rows is adjusted by calling adjustRows.

```
public boolean isVisibilityAdjusted()
```
    Returns the time scale visibility adjusted status. This only has meaning when there is a visibility policy associated to the time scale.
    
    Returns:
    
    When the rows need to be adjusted, false is returned. The default value is false.
    
    Since:

```
public void setVisibilityAdjusted(boolean visibilityAdjusted)
```
    Sets whether the rows visibility should be adjusted or not. This only has meaning when there is a visibility policy associated to the time scale.
    
    Parameters:
    
    visibilityAdjusted - Set to false so that at the next paint request, the time scale will take any existing visibility policy into account for row adjustment.

```
@Deprecated
public void computeCalendar()
```
    Deprecated. Beginning with Perforce JViews 8.7, this method is called automatically and is considered part of the internal implementation. This method should not be called from user code.
    
    Updates this scale's calendar to match the locale and timezone. This method is automatically called whenever the scale paints itself or when the timezone is changed.
    
    See Also:
    
    getCalendar(), getCalendar(Date), setTimeZone(TimeZone), setLocale(Locale)
  - 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.

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.
  - 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.

public TimeZone getTimeZone()

    This method returns the time zone of this scale.
  - isConstantZoomFactorOnWidthChange
```
public boolean isConstantZoomFactorOnWidthChange()
```
    Returns whether the visible duration of the scale will be modified when its width changes in order to maintain a constant zoom factor. If false, the visible duration of the scale stays the same and its zoom factor is modified when the width of the scale changes. The default value is true.
    When multiple IlvTimeScrollable user interface components have their time scrolling synchronized through an IlvBasicTimeScrollController or one of its subclasses, all of the scrollable components should be placed in a container that ensures that they maintain equal widths. Their constantZoomFactorOnWidthChange properties must also be set to the same value. When the GUI resizes, each scrollable component is responsible for computing its own duration change. When a time scale is added to an IlvHierarchyChart, its constantZoomFactorOnWidthChange property is set to match that of the chart.

public void setConstantZoomFactorOnWidthChange(boolean enabled)
```
    Sets if the visible duration for the scale will be modified in order to maintain a constant zoom factor when the width of the scale changes. If disabled, the visible duration of the scale stays the same and the zoom factor is modified when the width of the scale changes. The default value is true.

    Parameters:
    
    enabled - Set to true so the zoom factor stays the same and the visible duration changes when the scale resizes. Set to false so the visible duration stays the same and the zoom factor changes.

public void setMinVisibleTime(Date min)
```
    Sets the minimum time that the scale can show in bounded scrolling mode.

```
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.IlvTimeInterval, java.util.Date, java.util.Date, ilog.views.gantt.IlvDuration) 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:
