public class RowExpandedEvent extends EventObject
RowExpandedEvent
is fired on behalf of a Gantt configuration by
an IlvVerticalExpansionMaster
to notify all registered
expandable
UI components when a node has been expanded within the data tree. If the node
that was expanded had ancestors that were also originally collapsed, they
were expanded also in order to make the desired node visible.
RowExpandedEvent
maintains an array of all the ancestor nodes
that had to be expanded in order to successfully expand and make visible the
desired node. The nodes are ordered from the highest level ancestor node
that was expanded first to the desired, lowest level node that was expanded
last.source
Constructor and Description |
---|
RowExpandedEvent(IlvGanttConfiguration ganttConfig,
IlvHierarchyNode[] expandedNodes,
IlvHierarchyNode[] visibleNodes,
int firstVisibleRow)
Constructs a new
RowExpandedEvent generated by the
specified Gantt configuration that can be used to notify its
registered IlvVerticalExpandable UI components when a node,
and possibly some of its ancestors, have been expanded within the tree
hierarchy. |

int |
getVisibleNodeCount()
Returns the number of nodes that became visible as a result of this
expansion event.
|
