Variables

  Type Name Description
Protected variable TAttribute< bool > AllowContinousZoomInterpolation Allow continuous zoom interpolation?
Protected variable bool bAllowContinousZoomInterpolation  
Protected variable bool bDrawGridLines Should we render the grid lines?
Protected variable bool bIsPanning Are we panning the view at the moment?
Protected variable bool bIsZooming Are we zooming the view with trackpad at the moment?
Protected variable bool bRequireControlToOverZoom Does the user need to press Control in order to over-zoom.
Protected variable bool bTeleportInsteadOfScrollingWhenZoomingToFit  
Protected variable FVector2D GridOrigin The position in the grid to begin drawing at.
Protected variable FVector2D MouseDownPositionAbsolute  
Protected variable int32 PreviousZoomLevel Previous Zoom Level
Protected variable float TotalGestureMagnify Cumulative magnify delta from trackpad gesture
Protected variable float TotalMouseDelta The Y component of mouse drag (used when zooming)
Protected variable FVector2D ViewOffset The position within the graph at which the user is looking
Protected variable FVector2D ViewOffsetStart  
Protected variable int32 ZoomLevel How zoomed in/out we are. e.g. 0.25f results in quarter-sized nodes.
Protected variable FCurveSequence ZoomLevelFade Curve that handles fading the 'Zoom +X' text
Protected variable FCurveSequence ZoomLevelGraphFade Fade on zoom for graph
Protected variable TUniquePtr< FZoomLevelsContainer > ZoomLevels The interface for mapping ZoomLevel values to actual node scaling values.

Overridden from SWidget

  Type Name Description
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 FReply

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

 Called when the mouse wheel is spun. This event is bubbled.
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 FReply

OnTouchEnded ( const FGeometry& MyGeometry,
const FPointerEvent& InTouchEvent
)

 Called when a touchpad touch is ended (finger lifted)
Public function Virtual FReply

OnTouchGesture ( const FGeometry& MyGeometry,
const FPointerEvent& GestureEvent
)

 TOUCH and GESTURES Called when the user performs a gesture on trackpad. This event is bubbled.
Public function Virtual Const bool Checks to see if this widget supports keyboard focus. Override this in derived classes.
Public function Virtual void

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

 Ticks this widget with Geometry.
