Syntax

UCLASS (MinimalAPI)  
class UWidgetBlueprintGeneratedClass : public UBlueprintGeneratedClass

Remarks

The widget blueprint generated class allows us to create blueprint-able widgets for UMG at runtime. All WBPGC's are of UUserWidget classes, and they perform special post initialization using this class to give themselves many of the same capabilities as AActor blueprints, like dynamic delegate binding for widgets.

Variables

  Type Name Description
Public variable UProperty TArray< TObjectPtr< UWidgetAnimation > > Animations  
Public variable UProperty assetregistrysearchable TArray< FName > AvailableNamedSlots Available Named Slots for content in a subclass.
Public variable UProperty uint32: 1 bCanCallInitializedWithoutPlayerContext Determines whether this widget blueprint can be initialized without a valid player context (PlayerController, etc.).
Public variable UProperty Transient uint32: 1 bCanCallPreConstruct  
Public variable UProperty TArray< FDelegateRuntimeBinding > Bindings  
Public variable UProperty TArray< FName > InstanceNamedSlots These are the set of named slots that can be used on an instance of the widget.
Public variable UProperty Transient TSet< FName > NameClashingInHierarchy  
Public variable UProperty TArray< FName > NamedSlots All named slots, even the ones that have content already filled into them by a parent class and are not available for extension.
Public variable UProperty Transient TSet< FName > NamedSlotsWithContentInSameTree  
Public variable UProperty TMap< FName, FGuid > NamedSlotsWithID All named slots mapped the assigned GUID of their UNamedSlot widget.
