This document describes the main changes that have been made to the JViews Gantt module since version 6.0.

Incompatibilities
General Changes
Library Changes
New Packages

• ilog.views.gantt.faces

New Interfaces and Classes

• ilog.views.gantt.graphic.IlvActivityTileLayout
• ilog.views.gantt.graphic.interactor.IlvGanttSheetInteractor

Modified Classes

• ilog.views.gantt.IlvJScrollGanttSheet
• ilog.views.gantt.IlvTimeScrollSupport
• ilog.views.gantt.IlvTimeScrollUtil
• ilog.views.gantt.graphic.IlvActivitySimpleLayout
• ilog.views.gantt.graphic.IlvGanttSheet
• ilog.views.gantt.graphic.IlvLinearTimeConverter
• ilog.views.gantt.graphic.IlvTimeConverter
• ilog.views.gantt.model.jdbc.IlvJDBCGanttModel
• ilog.views.gantt.model.table.IlvTableGanttModel
• ilog.views.gantt.scale.IlvTimeScale.PaintContext
• ilog.views.gantt.swing.IlvAbstractJTreeRenderPolicy

Incompatibilities

• The IlvTimeConverter interface defines the new isLinear method.
• IlvJDBCTableGanttModel now uses IlvRowSetTableModel instances internally instead of IlvJDBCTableModel instances.
• The protected IlvAbstractJTreeRenderPolicy _tree field has been renamed to tree
• APIs of the IlvActivity, IlvResource, IlvConstraint, and IlvReservation interfaces that were originally deprecated in JViews 5.5 have now been removed. As a result, the getGanttModel methods of IlvAbstractActivity, IlvAbstractResource, IlvAbstractConstraint, and IlvAbstractReservation have been changed from public to protected access.

General Changes

• Non-linear time converters are now supported by the Gantt and Schedule charts.
• Mouse wheel support has been added to the Gantt and Schedule charts.
• The IlvGanttSheetInteractor base class has been introduced to assist in creating custom interactors.
• Redraw session support has been added to the Gantt sheet. This allows the user to optimize batch updates to the Gantt and Schedule charts.
• The new JViews Gantt Faces components allow you to easily build JavaServer Pages (JSP) that are compliant with the JavaServer Faces (JSF) user interface framework for Java Web application.

Library Changes

New Packages

ilog.views.gantt.faces

This package (and its subpackages) contains the gantt specific JSF components, renderers and JSP tags.

New Interfaces and Classes

ilog.views.gantt.graphic.IlvActivityTileLayout

IlvActivityTileLayout arranges concurrent activities within a Gantt row by subdividing the row into the minimum necessary subrows and tiling the activity graphics. This new layout has many more options and supercedes the IlvActivityLogisticLayout.TILE layout.

ilog.views.gantt.graphic.interactor.IlvGanttSheetInteractor

IlvGanttSheetInteractor is the base class for interactors that can be set on a Gantt sheet.

Modified Classes

ilog.views.gantt.IlvHierarchyChart

• Overview of new features:
  • Mouse Wheel support to scroll in and out and zoom the Gantt sheet
• New methods:
  • isMouseWheelEnabled(): Indicates whether or not scrolling and zooming will take place in response to movement of the mouse wheel.
  • setMouseWheelEnabled(boolean): Enables/disables scrolling and zooming in response to movement of the mouse wheel.
  • setTimeConverter(IlvTimeConverter): Sets the time converter used by the Gantt sheet and the time scale.


• New fields:
  • TIME_CONVERTER_PROPERTY: Identifies a change to the chart's time converter.

ilog.views.gantt.IlvJScrollGanttSheet

• Overview of new features:
  • Mouse Wheel support to scroll in and out and zoom the Gantt sheet
• New methods:
  • isMouseWheelEnabled(): Indicates whether or not scrolling and zooming will take place in response to movement of the mouse wheel.
  • setMouseWheelEnabled(boolean): Enables/disables scrolling and zooming in response to movement of the mouse wheel.

ilog.views.gantt.IlvTimeScrollSupport

• New methods:
  • computeVisibleTimeScroll(int, int): Computes the beginning of the visible interval that will cause the time at position x0 to scroll to position x1.

ilog.views.gantt.IlvTimeScrollUtil

• New fields:
  • DEFAULT_DURATION: The default scrollable duration.
  • DEFAULT_TIME: The default scrollable time.

ilog.views.gantt.graphic.IlvActivitySimpleLayout

• New fields:
  • DEFAULT_VERTICAL_MARGIN: The default vertical margins of 2.

ilog.views.gantt.graphic.IlvGanttSheet

• Overview of new features:
  • Redraw session support has been added so that batch updates can be optimized.
• New methods:
  • beginRedrawSession(boolean): Starts a redraw session that must be terminated by calling endRedrawSession.
  • endRedrawSession(): Ends a redraw session that was begun by calling beginRedrawSession.


• New fields:
  • TIME_CONVERTER_PROPERTY: Identifies a change to the Gantt sheet's time converter.

ilog.views.gantt.graphic.IlvLinearTimeConverter

• New methods:
  • isLinear(): Returns whether the time converter is continuous and linear.

ilog.views.gantt.graphic.IlvTimeConverter

• Overview of new features:
  • Non-linear time converters are now supported.
• New methods:
  • isLinear(): Returns whether the time converter is continuous and linear.

ilog.views.gantt.model.jdbc.IlvJDBCGanttModel

• Overview of new features:
  • Read/Write support
• New constructors:
  • IlvJDBCGanttModel(boolean): Builds an IlvJDBCGanttModel that will be configured later on.
  • IlvJDBCGanttModel(Connection, String, Map, String, Map, String, Map, Object[], String, Map, boolean): Builds an IlvJDBCGanttModel from a single JDBC Connection, four queries and mapping information from queries columns to gantt properties.


• New methods:
  • isReadOnly(): Returns whether or not this model is read-only.

ilog.views.gantt.model.table.IlvTableGanttModel

• New methods:
  • configureHierarchyChart(IlvHierarchyChart, boolean): Configures the given IlvHierarchyChart so that it fits the IlvTableGanttModel.

ilog.views.gantt.scale.IlvTimeScale.PaintContext

• New methods:
  • computeVisibleTimeScroll(int, int): Computes the beginning of the visible interval that will cause the time that currently corresponds with the position x0 to instead correspond with the position x1.

ilog.views.gantt.swing.IlvAbstractJTreeRenderPolicy

• Incompatibilities:
  • The protected _tree field has been renamed to tree.
• New fields:
  • tree: The tree for which this is the rendering policy.

Example Changes

• Mouse wheel support has been enabled in the samples.
• JSF example: This new example shows how to use the JViews Gantt JSF components to display and interact on a Gantt or Schedule chart in a server environment.
