PaintLaneBackground ( const FGeometry& AllottedGeometry,
const FSlateRect& MyCullingRect,
FSlateWindowElementList& OutDrawElements,
int32 LayerId,
const FWidgetStyle& InWidgetStyle
)

  
Public function void Sets the vertical offset of this track lane and all parent track lanes given the vertical offset of a particular outliner item inside the current track lane (i.e. an outliner item that's a child of the item that created this track lane) Note that the given item could actually be the one that created this track lane.

  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 void

OnArrangeChildren ( const FGeometry& AllottedGeometry,
FArrangedChildren& ArrangedChildren
)

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

OnCursorQuery ( const FGeometry& MyGeometry,
const FPointerEvent& CursorEvent
)

 The system asks each widget under the mouse to provide a cursor. This event is bubbled.
Public function Virtual FReply

OnMouseButtonDown ( const FGeometry& MyGeometry,
const FPointerEvent& MouseEvent
)

 MOUSE INPUT The system calls this method to notify the widget that a mouse button was pressed within it.
Public function Virtual FReply

OnMouseButtonUp ( const FGeometry& MyGeometry,
const FPointerEvent& MouseEvent
)

 The system calls this method to notify the widget that a mouse button was release within it.
Public function Virtual FReply

OnMouseMove ( const FGeometry& MyGeometry,
const FPointerEvent& MouseEvent
)

 The system calls this method to notify the widget that a mouse moved within it.
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.
Public function Virtual void

Tick ( const FGeometry& AllottedGeometry,
const double InCurrentTime,
const float InDeltaTime
)

 Ticks this widget with Geometry.
