IOperationStack Interface

Provides access to members that control the Operation Stack.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

An application can implement an OperationStack to provide undo and redo facilities. As you carry out operations, they are added to the stack, then you can use undo and redo in the application to manipulate the stack to undo or redo the operations.

Classes that implement IOperationStack

Classes Description

Remarks

ArcMap has an OperationStack, which can be obtained with the IMxDocument::OperationStack property. ArcMap’s buttons and tools wrap their actions in an operation and add the operations to the stack.

Depending on your scenario, there are different methodologies for creating an operation and adding it to the OperationStack.
