Resequencing by drag-and-drop on a flow

You can drag-and-drop a PERT node onto a flow to change the node order and put the dragged node in between the two nodes previously connected by the flow. For example:

Dragging the node D on to the flow between A and B results in the following order:

• The dragged node is disconnected from its old predecessors and successors.

• New flows are created between all predecessors of the dragged node to all successors of the dragged node.

• If the dragged node has either predecessors or successors, but not both (meaning if it was either the first node in a chain or the last node in a chain), no substitute flow is created.

• The dragged node is connected to its new predecessor and successor. The only predecessor of the dragged node is the source of the flow on to which it was dragged. The only successor of the dragged node is the target of the flow on to which it was dragged.

When dragging the node over a flow, the target flow is selected to indicate that it is the target for the drop.
