public class IlvGanttSheet
extends IlvManagerView
implements IlvVerticalExpandable, IlvTimeScrollable
```
The IlvGanttSheet class is a lightweight graphical component that displays activities, constraints, and reservations. It can be added to a Gantt configuration as an expandable slave component by invoking the IlvGanttConfiguration.addVerticalExpandable(ilog.views.gantt.IlvVerticalExpandable) method.

This class is a subclass of the Perforce JViews IlvManagerView class. It contains a JViews grapher (IlvGrapher) to display the activities and constraints. The activities displayed in the IlvGanttSheet are JViews graphic object instances of the class IlvActivityGraphic for the activities and IlvConstraintGraphic for the constraints.
As this class is a view of a manager, you can set interactors on it. These interactors provide different types of interactions. The library includes predefined interactors to select and edit the activities in the gantt sheet, such as IlvGanttSelectInteractor, but you can create your own type of interactor using IlvManagerViewInteractor.

    Returns whether the Gantt sheet is displaying constraints. The default value is true for an IlvGanttConfiguration that has a row type of ACTIVITY_ROWS, as in a Gantt chart. The default value is false for a configuration that has a row type of RESOURCE_ROWS, as in a Schedule chart.

    Displaying constraints in a resource-oriented Schedule chart is only guaranteed to work correctly if each activity participates in 0 or 1 reservations. If an activity participates in 2 or more reservations, the Schedule chart will not display constraints in an intuitive manner. The Gantt sheet does not check to ensure that this is the case. It is up to the data model to adhere to this restriction.

public void setExpandableGanttConfigurationImpl(IlvGanttConfiguration ganttConfig)

The Gantt sheet will be subsequently informed when a data model is set or replaced via the ganttModelChanged event.
    Warning: This method is considered to be part of an IlvVerticalExpandable's internal implementation and is not a public API. Only the Gantt configuration should invoke this method.

    This method is called to fire a visible duration value modification.
  - beginRedrawSession
```
public void beginRedrawSession(boolean redrawSheet)
```
    Starts a redraw session that must be terminated by calling endRedrawSession(). Redraw sessions can be nested, graphical damage is accumulated, and the Gantt sheet is redrawn when the outermost enclosing session is ended. The redrawSheet argument indicates whether the entire Gantt sheet is repainted when the final redraw session terminates or whether damage is accumulated for individual graphics and only the damaged region of the sheet is repainted.
    Redraw sessions are designed to improve performance during batch updates to the Gantt data model and/or the styling of activities, constraints, and reservations. For performance reasons, the activity layout of the Gantt sheet is suspended during redraw sessions and graphics are not guaranteed to have valid bounding boxes. Because of this, during a redraw session it is not recommended to perform any translation or zooming changes on the Gantt sheet that depend on knowledge of activity graphic or Gantt row positioning.
    
    Parameters:
    
    redrawSheet - Indicates whether the entire Gantt sheet is repainted when the final redraw session terminates. If a redraw session is already active for the entire sheet, then the value of this argument is ignored.
    
    Since:
    
    JViews 6.5
  - endRedrawSession
```
public void endRedrawSession()
```
    Ends a redraw session that was begun by calling beginRedrawSession(boolean). If the redraw session that is ended was the outermost one, then the Gantt sheet will be redrawn and all accumulated graphical damage will be repaired.

  - isConstantZoomFactorOnWidthChange
```
public boolean isConstantZoomFactorOnWidthChange()
```
    Returns whether the visible duration of the Gantt sheet is modified when its width changes in order to maintain a constant zoom factor. If false, the visible duration of the Gantt Sheet will remain the same and its zoom factor will be modified when the width of the sheet 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 and their constantZoomFactorOnWidthChange properties must be set to the same value. When the GUI resizes, each scrollable component is responsible for computing its own duration change.

    Sets whether the visible duration of the Gantt sheet will be modified when its width changes in order to maintain a constant zoom factor. If disabled, the visible duration of the Gantt sheet will stay the same and its zoom factor will be modified when the width of the sheet changes. The default value is true.

    Translates the view. This method translates the transformer of the view.
    
    Overrides:
    
    translate in class IlvManagerView
    
    Parameters:

```
public void ensureVisible(IlvGraphic graphic,
                          int margin)
```
    Scrolls the Gantt sheet if necessary to ensure that the specified graphic is visible to the user. Note that this method does not zoom the view, but only translates it. Along the X axis, the specified margin is added to both sides of the graphic. If the graphic is too wide to be made completely visible in the Gantt sheet, preference is given to the leading edge specified according to the sheet's component orientation. Along the Y axis, the Gantt sheet is scrolled vertically so that the topmost and bottommost rows that the graphic intersects are both visible. If the graphic is too high to be made completely visible in the Gantt sheet, preference is given to the top of the graphic.
    
    Use IlvHierarchyChart.makeRowDisplayed(IlvHierarchyNode) or IlvGanttConfiguration.makeRowDisplayed(IlvHierarchyNode) instead if you only want to scroll a specific row vertically to make it visible in the Gantt sheet. Similarly, if you want to zoom horizontally to make graphics visible, use the IlvManagerView.fitTransformerToContent(Insets) or IlvManagerView.fitTransformerToArea(Insets, FitAreaCalculator, int) methods.
    
    Parameters:
    
    graphic - The graphic.
    
    margin - The margin around the graphic, in pixels.

```
public boolean isRefreshMilestoneRenderer()
```
    When the time interval of an activity becomes null, the start and end times become identical. The activity is then called a milestone. If this function returns true, the activity renderer will be refreshed by calling the createActivityRenderer() method of the Gantt sheet activity-renderer factory.
    Conversely, when a milestone becomes a normal activity, its renderer will be refreshed if this function returns true.
    
    Note: This mechanism applies only to leaf activities that have no children.
    
    Returns:
    
    if an activity renderer should be refreshed.
