Interface IlvVerticalExpandable

All Superinterfaces:

EventListener, VerticalExpansionListener, VerticalExpansionListener2

All Known Implementing Classes:

IlvGanttSheet, IlvJTable, IlvJTree

public interface IlvVerticalExpandable
extends VerticalExpansionListener2

The IlvVerticalExpandable interface defines the behavior of all the ui components that can have their row expand/collapse and visibility behavior coordinated by an IlvGanttConfiguration. Typically, a user interface component does not implement this interface directly. Instead, an adapter class is created. This class implements this interface and mediates between the component and the Gantt configuration. An IlvVerticalExpandable is added to a Gantt configuration by calling the IlvGanttConfiguration.addVerticalExpandable(ilog.views.gantt.IlvVerticalExpandable) method.

Method Detail

setExpandableGanttConfigurationImpl

void setExpandableGanttConfigurationImpl(IlvGanttConfiguration ganttConfig)

Sets the Gantt configuration that this ui component is coordinating with. This method is invoked when the component is added to the configuration via the IlvGanttConfiguration.addVerticalExpandable(ilog.views.gantt.IlvVerticalExpandable) method. The expandable component should initially synchronize its display with the Gantt configuration at this point. Note however, that the Gantt configuration may or may not have a valid data model at this time and this must be taken into account. The expandable will be subsequently informed when a data model is set or replaced via the ganttModelChanged(ilog.views.gantt.event.GanttModelChangedEvent) 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.

Parameters:

ganttConfig - The Gantt configuration that this component is being added to, or null if this component is being removed from its Gantt configuration.

ganttModelChanged

void ganttModelChanged(GanttModelChangedEvent event)

This method is invoked by the Gantt configuration when the data model has been replaced. Logically, the root row has also changed as a result (unless both the old and new gantt data models have a null root node). However, separate VerticalExpansionListener.rowsInserted(ilog.views.gantt.event.RowsInsertedEvent) or VerticalExpansionListener.rowsRemoved(ilog.views.gantt.event.RowsRemovedEvent) events will not be invoked by the Gantt configuration as a result of the data model change being reported.

Parameters:

event - The event.

validateRowHeights

void validateRowHeights()

Ensures that the heights of all rows are up-to-date.
