ReturnFromDrillDown(| parGraphNpp | | ,graphName | | ,NodeId | | ,NodeName | | ,Xnode | | ,Ynode |)
| ReturnFromDrilldown | Unhides, calculates and draws the original graph object |
| parGraphNpp | A LONG integer that identifies the GraphID FEQ to process |
| graphName | String text that identifies the original graph name. |
| NodeID | The positional node value of the drilldown graph control that is passed to the active graph control. |
| NodeName | The positional node name of the drilldown graph control that is passed to the active graph control. |
| Xnode | The positional X Node coordinate of the drilldown graph control that is passed to the active graph control. |
| Ynode | The positional Y Node coordinate of the drilldown graph control that is passed to the active graph control. |
The ReturnFromDrilldown method is used to “drill back” to the original graph object. It is designed to restore the original graph object's state prior to calling the Drilldown method.
Optional parameters can be processed by the target “drill back” graph control. This allows the target control to be related to the drilldown graph object.
Implementation:
The ReturnFromDrilldown method is called from the TakeEventOfParent method when the graph event Event:ReturnFromDrillDown is posted. This event is triggered when the user double-clicks on a valid graph node, or selects the “Return from DrillDown” popup menu item.
