![]() | CachedResourceDictionaryExtension | Provides a cached dictionary that associates resource dictionaries with their URIs. |
![]() | ClipboardData | Represents the data passed around with the clipboard. |
![]() | ContextItem | Represents a base class from which all context items must derive. This class is abstract. |
![]() | ContextItemManager | Represents a class that maintains a set of context items published into the designer editing context. This class is abstract. |
![]() | CutCopyPasteHelper | Provides functions to cut, copy, and paste items. |
![]() | DefaultTypeArgumentAttribute | Specifies the default type for a generic type activity. |
![]() | DesignerConfigurationService | |
![]() | DragDropHelper | Represents a helper class to assist dragging and dropping inside the Windows Workflow Designer. |
![]() | DynamicArgumentDesignerOptions | Provides options for the dynamic argument designer. |
![]() | DynamicArgumentDialog | Represents a dialog box for a dynamic argument element. |
![]() | EditingContext | Contains contextual state information for a designer, such as the WorkflowDesigner. This includes permanent state information, such as the list of services running in the designer. It also includes transient state consisting of context items including the set of currently selected objects as well as the editing tool being used to manipulate objects on the design surface. |
![]() | ServiceManager | Implements IserviceProvider and provides access to services offered by the editing context. |
![]() | TypeResolvingOptionsAttribute | Used to configure how a Windows Workflow Designer initializes type-resolver and type-browser dialogs to enable a user to select a type for arguments, variables, and generic type activities. |
![]() | UndoEngine | Provides undo and redo operation implementations for designers. |
![]() | UndoUnit | Represents a single unit of undoable work. Such a unit is added to an undo stack, and methods are provided to traverse the stack and perform an undo action on each unit. |
![]() | UndoUnitEventArgs | Represents the argument that is passed to the UndoUnitAddedevent() event. |
![]() | WorkflowDesigner | Provides a designer canvas, which renders the visual representation of a workflow model as it is being designed. |
![]() | WorkflowDesignerColors | Enables colors and color gradients to be associated with aspects of the elements and shell bars used in the Windows Workflow Designer user interface. |
![]() | WorkflowElementDialog | Represents a dialog box for the workflow element. |
![]() | WorkflowFileItem | Represents aContextItem that is published in the editing context and that provides information about the file that the current editing session is based on. Note that it is possible that the WorkflowFileItem value is nullptr, for instance if a WorkflowDesigner operates directly on an object instance and does not serialize into a file-based format. |
![]() | WorkflowItemPresenter | Provides a visual editor to edit ModelItem objects, and provides an area for the user to drag and drop, and otherwise edit composed elements. |
![]() | WorkflowItemsPresenter | Represents a control that can be used to present a collection of objects on a design surface. |
![]() | WorkflowViewElement | Base class for any UI element that appears on the designer canvas and that visually represents an instance of an atomic item that can be edited. |
![]() | XamlLoadErrorInfo | Contains information about the error generated by the XAML Reader when loading an XML file, including the name of the file and the location in the file where the error occurred. |
| Interface | Description | |
|---|---|---|
![]() | IActivityTemplateFactory | Defines the factory method that a class implements to create a template that encapsulates "placeholder" Activity objects. |
![]() | IActivityToolboxService | Represents a service used to update Toolbox contents from a Designer. |
![]() | ICompositeView | Provides methods to copy, cut, move, delete, and paste objects. |
![]() | ICompositeViewEvents | Handles events that can occur during the display of ICompositeView items. |
![]() | IIntegratedHelpService | Defines the contract between Visual Studio 2010 and the Windows Workflow Designer for integrated help provided. |
![]() | IModalService | Enables notification to a host application that a modal dialog is displayed. |
![]() | IWorkflowDesignerStorageService | Infrastructure. Provides a service available to the Windows Workflow Designer host to store and retrieve data. |
![]() | IXamlLoadErrorService | Defines how the Visual Studio host displays the list of errors generated by the XAML reader when loading the XAML file. |
| Delegate | Description | |
|---|---|---|
![]() | PublishServiceCallback | A delegate that references a method that publishes an instance of a service. |
![]() | PublishServiceCallback<TServiceType> | A generic delegate that references a method that publishes an instance of a service. |
![]() | SubscribeContextCallback | Defines a callback method that will be invoked when a context item changes. |
![]() | SubscribeContextCallback<TContextItemType> | Defines a callback method that will be invoked when a context item changes. |
![]() | SubscribeServiceCallback | Represents a delegate that is a callback for service subscriptions. |
![]() | SubscribeServiceCallback<TServiceType> | Represents a generic delegate that is a callback for service subscriptions. |
