Detailed Description

A linear undo model with one undo and one redo stack.

Derived from UndoModel AND itk::Object. Invokes ITK-events to signal listening GUI elements, whether each of the stacks is empty or not (to enable/disable button, ...)

◆ Redo() [1/3]

bool mitk::LimitedLinearUndo::Redo ( )

overridevirtual

Undoes the last changes.

Reads the top element of the Redo-Stack, executes the operation, swaps the OperationEvent-Operation with the Undo-Operation and sets it to Undo-Stack

Implements mitk::UndoModel.

◆ Redo() [2/3]

bool mitk::LimitedLinearUndo::Redo ( bool )

Reimplemented in mitk::VerboseLimitedLinearUndo.

◆ SetUndoLimit()

void mitk::LimitedLinearUndo::SetUndoLimit ( std::size_t limit )

overridevirtual

Sets a limit on the size of the undo history. If the limit is reached, the oldest undo items will be dropped from the bottom of the undo stack. The 0 value means that there is no limit.

Parameters

limit the maximum number of items on the stack

Implements mitk::UndoModel.

◆ Undo() [1/3]
