Variables

  Type Name Description
Protected variable uint8: 1 bIsSeperator A flag that indicates that this is a separator slate node and has no valid data
Protected variable TArray< FSubobjectEditorTreeNodePtrType > Children Any children that this subobject has in the hierarchy, used to collapsed things within in the tree
Protected variable FSubobjectDataHandle DataHandle The data source of this subobject
Protected variable uint8 FilterFlags  
Protected variable TUniquePtr< FScopedTransaction > OngoingCreateTransaction Scope the creation of a node which ends when the initial 'name' is given/accepted by the user, which can be several frames after the node was actually created.
Protected variable FSubobjectEditorTreeNodePtrType ParentNodePtr Pointer to the parent of this subobject
Protected variable FOnRenameRequested RenameRequestedDelegate Handles rename requests

Functions

  Type Name Description
Public function void

AddChild ( FSubobjectEditorTreeNodePtrType AttachToPtr
)

 Add the given slate node to our child array and set it's parent to us This had no effect on the actual structure of the subobjects this node represents it is purely visual
Public function void Used to update the EFilteredState::ChildMatches flag for parent nodes, when this item's filtration state has changed

Public function FSubobjectEditorTreeNodePtrType

FindChild ( const FSubobjectDataHandle& InHandle
)

 Attempts to find the given subobject handle in the slate children on this node. Nullptr if none are found.
Public function Const const TArray< FSubobjectEditorTreeNodePtrType > &  
Public function Const const UActorComponent * If this subobject is an actor component, then return its template. Otherwise it will return null
Public function Const FSubobjectDataHandle Get the subobject handle that this slate node is representing.
Public function Const FSubobjectData * Get a pointer to the subobject data that this slate node is representing.
Public function Const FString Get the display name of this single tree node
Public function Const const UObject *

GetObject ( bool bEvenIfPendingKill
)

  
Public function void  
Public function Const FSubobjectEditorTreeNodePtrType Get the slate parent of this single tree node

IsAttachedTo ( FSubobjectEditorTreeNodePtrType InNodePtr
)

 Returns true if this node is attached to the given slate node.

Public function Const bool

IsDirectlyAttachedTo ( FSubobjectEditorTreeNodePtrType InNodePtr
)

  
Public function Const bool Query that determines if this item should be filtered out or not
Public function Const bool  
Public function Const bool Returns true if this is the root actor node of the tree.
Public function Const bool

IsValid ()

 Returns true if this subobject data handle is valid.
Public function Const bool

MatchesFilterType ( const UClass* InFilterType
)

 Returns whether the node will match the given type (for filtering)
Public function void

RefreshCachedChildFilterState ( bool bUpdateParent
)

 Updates the EFilteredState::ChildMatches flag, based off of children's current state
Public function bool

RefreshFilteredState ( const UClass* InFilterType,
const TArray< FString >& InFilterTerms,
bool bRecursive
)

 Refreshes this item's filtration state. Set bRecursive to 'true' to refresh any child nodes as well
Public function void

RemoveChild ( FSubobjectEditorTreeNodePtrType InChildNodePtr
)

 Remove the given slate node from our children array.
Public function void

SetCachedFilterState ( bool bMatchesFilter,
bool bUpdateParent
)

 Sets this item's filtration state.
Public function void  
Public function void Sets up the delegate for a rename operation
