Detailed Description

This class represents a component, that provides undo facilities.

The UndoComponent creates and registers QUndoStack as a service in the service locator. It is also has an IInteractiveExtension extension, that adds undo buttons to the menu and toolbar.

Registered services:

QUndoStack;

See Also: UndoInteractiveExtension

Constructor & Destructor Documentation

UndoComponent::UndoComponent ( QObject * parent = nullptr )

Initializes a new instance of the UndoComponent class and also registers UndoInteractiveExtension.

Member Function Documentation

void UndoComponent::onShutdown ( IServiceLocator * serviceLocator )

protectedvirtual

Shuts down the component.

Reimplemented from BaseComponent.

bool UndoComponent::onStartup ( IServiceLocator * serviceLocator )

protectedvirtual

Registers undo dialog in the dialog service.

Parameters

serviceLocator should be a reference to AbstractApplication object.

Returns: false, if serviceLocator is not a reference to AbstractApplication object. Otherwise, return true.

Reimplemented from BaseComponent.
