Member Function Documentation

def UM.Operations.Operation.Operation.mergeWith	(		self,
			other
	)

Perform operation merging.

This will be called by OperationStack to perform merging of operations. If this operation can be merged with other, it should return a new operation that is the combination of this operation and other. If it cannot be merged, False should be returned.

Parameters

other

Operation The operation to merge with.

Returns

An operation when this operation and other can be merged, or False if they cannot be merged.

def UM.Operations.Operation.Operation.push	(		self,
			None
	)

Push the operation onto the stack.

This is a convenience method that pushes this operation onto the Application's operation stack.

def UM.Operations.Operation.Operation.redo	(		self,
			None
	)

Redo the operation.

This should be reimplemented by subclasses to perform all actions necessary to redo the operation.

Note

This is automatically called when the operation is first put onto the OperationStack.

def UM.Operations.Operation.Operation.undo	(		self,
			None
	)

Undo the operation.

This should be reimplemented by subclasses to perform all actions necessary to redo the operation.
