Class IlvActivityGraphicReshapeInteractor

java.lang.Object

ilog.views.IlvObjectInteractor

ilog.views.gantt.graphic.interactor.IlvGanttObjectInteractor

ilog.views.gantt.graphic.interactor.IlvActivityGraphicReshapeInteractor

All Implemented Interfaces:

Serializable

public class IlvActivityGraphicReshapeInteractor
extends IlvGanttObjectInteractor

This interactor is the edition interactor for the class IlvActivityGraphicSelection. It reshapes an instance of IlvActivityGraphic. More precisely, it does not reshape the activity graphic directly, but changes the start time and end time of the activity represented by the activity graphic.

This interactor is used together with a IlvGanttSelectInteractor. It becomes active when an IlvActivityGraphic object is selected by an IlvGanttSelectInteractor object.

This interactor has two working modes: Opaque Reshape and Ghost Reshape.

• In Opaque Reshape mode, the object is resized at each drag event.
• In Ghost Reshape mode, the object is resized only when the user releases the mouse button.

The working mode is defined by the IlvGanttSelectInteractor object installed for the Gantt sheet. The default mode is Opaque Reshape.

Method Detail

addActivityGraphicInteractorListener

public static void addActivityGraphicInteractorListener(IlvGanttSheet ganttSheet,
                                                        ActivityGraphicInteractorListener listener)

Adds the given listener subscribed for receiving reshape notifications.

Parameters:

ganttSheet - The implicated Gantt sheet.

listener - The listener.

Since:

JViews 8.1

removeActivityGraphicInteractorListener

public static void removeActivityGraphicInteractorListener(IlvGanttSheet ganttSheet,
                                                           ActivityGraphicInteractorListener listener)

Removes the given listener.

Parameters:

ganttSheet - The implicated Gantt sheet.

listener - The listener.

Since:

JViews 8.1

getCursor

public Cursor getCursor(int direction)

Returns the cursor used for editing.

Parameters:

direction - the direction of the reshaping.

Returns:

The Cursor.

processMousePressed

protected boolean processMousePressed(MouseEvent event)

Processes mouse pressed events.

Parameters:

event - The MouseEvent.

Returns:

True if the event was used.

processMouseMoved

protected boolean processMouseMoved(MouseEvent event)

Processes mouse moved events.

Parameters:

event - The MouseEvent

Returns:

True if the event was used.

processMouseDragged

protected boolean processMouseDragged(MouseEvent event)
