#TTP 312311 - ROCKET: TASK: Add a "Documentation Node" #Branch UE4 #Proj BlueprintGraph, EdGraph, Kismet, KismetCompiler, GraphEditor, Documentation, EditorStyle #Change Updated UEdGraphSchema to include an interface call to retrieve an FEdGraphSchemaAction to create documentation nodes. At this point only the K2 interfaces implement this. #Change Updated UEdGraphSchema_K2 to include a call to retrieve an FEdGraphSchemaAction to create documentation nodes. This is used to add the actions to the blueprint palette and context menus. #Add Added FEdGraphSchemaAction_K2AddDocumentation in EdGraphSchema_K2_Actions.h/cpp to implement the calls in UEdGraphSchema to create documenation nodes from palette and context menus. #Change Modified FK2ActionMenuBuilder to provide a static call to create a documentation action in the same style as the comment. Additionally added calls to FK2ActionMenuBuilder::GetPaletteActions and FK2ActionMenuBuilder::GetContextAllowedNodeTypes to call this to add entries in the palette and context menus. #Add Added a new Brush GraphEditor.Documentation_16x, for the context menu icon in SlateEditorStyle.cpp. #Change Modified GetPaletteItemIcon in SBlueprintPalette.cpp to return the new icon for the DocumentationNode #Change Modified FKismetCompilerContext::IsNodePure to include the Documentaton node in the drop through ensure test to prevent asserts on compling if a documentation node is present. #Change Added an entry for Documentation node in FNodeFactory::CreateNodeWidget. #Change Modified IDocumentationPage interface to provide the ability to provide a TextWrapAt Attribute so this can be set before creating excerpt content if desired. #Change Modified the UDNParser to control text wrap at values in the created widgets using a float Attribute WrapAt, Added a set call in the DocumentationPage and made the default behaviour mimic the code it replaced. #Add Added the class UEdGraphNode_Documentation implemented in EdGraphNode_Documentation.h and UEdGraph.cpp, this is the UObject implementation for the documentation nodes. #Add Added the class SGraphNodeDocumentation as the GraphPanel implementation of the EdGraphNode_Documentation. #Change Moved the resizable code from SGraphNodeComment into a SGraphNodeResizable and changed SGraphNodeComment and SGraphNodeDocumentation inherit from it to avoid duplicating code. #Change Added a documentation specific details customisation so the excerpts can be displayed as combo button. #Change Added FBlueprintDocumentationDetails into BlueprintDetailsCustomization.h/cpp to handle the user interaction with the documentation node in the BP Editor.
