Class RowsRemovedEvent

java.util.EventObject

ilog.views.gantt.event.RowChildEvent

ilog.views.gantt.event.RowsRemovedEvent

All Implemented Interfaces:

Serializable

public class RowsRemovedEvent
extends RowChildEvent

RowsRemovedEvent is fired on behalf of a Gantt configuration by an IlvVerticalExpansionMaster to notify all registered expandable UI components when children have been removed from a common parent node in the displayed data tree. If the configuration's row organization is ACTIVITY_ROWS then this event is similar to an ActivitiesRemovedEvent. Otherwise, the configuration's row organization is RESOURCE_ROWS and this event is similar to a ResourcesRemovedEvent. In either case, visibility info about the removed nodes is provided that is not available from the data model events themselves. All, some, or none of the nodes removed from the data model may have been visible. The child nodes must be siblings and direct descendents (not grandchildren) of the specified parent node.

Constructor Detail

RowsRemovedEvent

public RowsRemovedEvent(IlvGanttConfiguration ganttConfig,
                        IlvHierarchyNode parent,
                        IlvHierarchyNode[] children,
                        int[] childIndices,
                        int[] childRows,
                        int[] hiddenRowCounts)

Constructs a new RowsRemovedEvent generated by the specified Gantt configuration that can be used to notify its registered IlvVerticalExpandable UI components when child nodes have been removed from a common parent.

Parameters:

ganttConfig - the Gantt configuration where the event originated

parent - the parent node which has had children removed. If the deletion being reported is the hierarchy's root node, parent should be null, children should be a single element array containing the root node, and childIndices should be a single element array with childIndices[0]=0.

children - the array of child IlvHierarchyNode's that have been removed. The nodes must be arranged in parallel with childIndices, ordered according to their indices within their common parent node from lowest to highest.

childIndices - an int array of the child node indices arranged in parallel with children, ordered from lowest to highest. The indices point to the original locations in the parent node where the children were removed.

childRows - an int array of the rows that each child node was visible on before it was removed. The rows numbers must be arranged in parallel with childIndices. A row number of -1 is used to indicate that the child node was not visible before it was removed.

hiddenRowCounts - an int array of the number of rows that were hidden as a result of each child node's removal. The row counts must be arranged in parallel with childIndices. Each row count includes the row that the child node was visible on plus any visible grandchildren and descendents. If the child was not originally visible, the row count will be 0.

Method Detail

getChildRows

public int[] getChildRows()

Returns the array of rows that each child node was visible on before it was removed. The rows are arranged in parallel with getChildIndices(), ordered according to each child node's index within its common parent, from lowest to highest. A row number of -1 indicates that the child node was not visible before it was removed.

Returns:

The array of rows.

getHiddenRowCounts

public int[] getHiddenRowCounts()

Returns the array of row counts that were hidden as a result of each child node's removal. The row counts are arranged in parallel with getChildIndices(), ordered according to each child node's index within its common parent, from lowest to highest. Each row count includes the row that the child node was visible on plus any visible grandchildren and descendents. If the child was not originally visible, the hidden row count for that node will be 0.

Returns:

The array of row counts.
