Syntax

struct FBlueprintDragDropMenuItem : public FEdGraphSchemaAction

Remarks

At certain times we want a single menu entry that represents a set of UBlueprintNodeSpawners (generally when all those UBlueprintNodeSpawners wrap the same UField). We do this to keep the menu less jumbled, and instead use the drag/drop action to present a sub-menu to the user (so they can pick the the node type that they want). We do this with both delegates and variable nodes (where the user can pick a getter vs. a setter, etc.).

This class represents those "consolidated" actions, and essentially serves as a FDragDropOperation spawner. It wraps a single UBlueprintNodeSpawner (any one of the set that it is supposed to represent), that it uses to determine the proper FDragDropOperation.

Constructors

	Type	Name	Description
		FBlueprintDragDropMenuItem ()	Default constructor for USTRUCT() purposes.
		FBlueprintDragDropMenuItem ( FBlueprintActionContext const& Context, UBlueprintNodeSpawner const* SampleAction, int32 MenuGrouping, FText InNodeCategory, FText InMenuDesc, FText InToolTip )	Sole constructor, which ensures that the RepresentativeAction member is set (and valid).
