StartGroup Method

Description

Used to specify that a group of "undoable" operations has started.

Syntax

Public Sub StartGroup()

Remarks

StartGroup and EndGroup are used to "group" a set of "undoable" operations together. Grouping the operations is useful as grouped operations can be undone or redone with a single call to Undo or Redo. If the operations are not grouped, you would have to call Undo or Redo for each operation performed.

Any "undoable" operations performed between StartGroup and EndGroup will be undone/redone with a single call to Undo or Redo.

In the sample below, a single Undo call will replace all deleted nodes, no matter how many were deleted.

Dim Node As FlowGraphNode

FlowGraph.UndoManager.StartGroup
For Each Node In FlowGraph.Selection
    Node.Remove
Next
FlowGraph.UndoManager.EndGroup
