Functions

  Type Name Description
Public function Virtual Const bool

CanBeSelected ( const FVector2D& MousePositionInNode
)

 Return if the node can be selected, by pointing given location

Public function Virtual Const FVector2D Override, when area used to select node, should be different, than it's size e.g. comment node - only title bar is selectable return size of node used for Marquee selecting
Public function Virtual Const void

GetDiffHighlightBrushes ( const FSlateBrush*& BackgroundOut,
const FSlateBrush*& ForegroundOut
)

 Used by GetDiffHighlights to generate outlines for diffed nodes
Public function Const TArray< SNodePanel::SNode::DiffHighlightInfo >

GetDiffHighlights ( const FDiffSingleResult& DiffResult
)

  
Public function Virtual Const FString

FNodeSet& NodeFilter,
bool bMarkDirty
)

  
Public function Virtual Const void

PerformSecondPassLayout ( const TMap< UObject*, TSharedRef< SNode > >& InNodeToWidgetLookup
)

 Performs second pass layout; only called if RequiresSecondPassLayout returned true
Public function void

RemoveSlot ( const ENodeZone::Type SlotId
)

  
Public function Virtual Const bool Returns true if this node is dependent on the location of other nodes (it can only depend on the location of first-pass only nodes)
Public function void

SetParentPanel ( const TSharedPtr< SNodePanel >& InParent
)

  
Public function Virtual Const bool Return false if this node should not be culled.

Overridden from SWidget

  Type Name Description
Public function Virtual Const FVector2D

ComputeDesiredSize ( float
)

 A Panel's desired size in the space required to arrange of its children on the screen while respecting all of the children's desired sizes and any layout-related options specified by the user.
Public function Virtual FChildren * All widgets must provide a way to access their children in a layout-agnostic way.
Public function Virtual Const float

GetRelativeLayoutScale ( int32 ChildIndex,
float LayoutScaleMultiplier
)

 What is the Child's scale relative to this widget.
Public function Virtual Const void

OnArrangeChildren ( const FGeometry& AllottedGeometry,
FArrangedChildren& ArrangedChildren
)

 Panels arrange their children in a space described by the AllottedGeometry parameter.
Public function Virtual Const int32

OnPaint ( const FPaintArgs& Args,
const FGeometry& AllottedGeometry,
const FSlateRect& MyCullingRect,
FSlateWindowElementList& OutDrawElements,
int32 LayerId,
const FWidgetStyle& InWidgetStyle,
bool bParentEnabled
)

 The widget should respond by populating the OutDrawElements array with FDrawElements that represent it and any of its children.
