For Developers — C++ Class Reference

This section maps user-facing features to C++ classes for developers who want to extend Quick Menu.

Core Architecture

Class Role
FQuickMenuModule Module startup, V hotkey registration, opens pie overlay
UQuickMenuSettings UDeveloperSettings — project settings
UQuickMenuGraphAsset UObject owning the UEdGraph
FQuickMenuGraphSchema Pin types, connection rules, context menus
FQuickMenuGraphEvaluator Walks graph to produce menu items
SQuickMenuWidget SLeafWidget — pie menu rendering and interaction
FQuickMenuGraphAssetEditor FAssetEditorToolkit — graph editor

Node Classes

Class User-Facing Name
UQMGraphNode_Root Root
UQMGraphNode_WheelOutput WheelOutput
UQMGraphNode_SubMenu SubMenu
UQMGraphNode_SwitchEditorContext Switch: Editor Context
UQMGraphNode_SwitchEditorMode Switch: Editor Mode
UQMGraphNode_SwitchSelectionCount Switch: Selection Count
UQMGraphNode_SwitchActorClass Switch: Actor Class
UQMGraphNode_SwitchBlueprintContext Switch: Blueprint Context

Action Base Class

All action nodes inherit from UQMGraphNode_ActionBase, which provides:

  • Label (FString) — display name
  • IconBrushName (FName) — Slate icon
  • IconTexture (UTexture2D*) — custom icon texture
  • WedgeColor (FLinearColor) — wedge color
  • bCompact (bool) — compact display mode
  • bAutoLabel (bool) — auto-generate label from properties

Creating a Custom Action Node

  1. Create a class inheriting from UQMGraphNode_ActionBase
  2. Override Resolve() — called when the wedge is clicked
  3. Override GetDisplayLabel() — returns the wedge label text
  4. Override GetNodeTitle() — returns the node title in the graph editor
  5. Optionally override IsActionVisible() — controls whether the wedge appears
  6. Register in QMActionRegistry.cpp → RegisterActions()
