Detailed Description

Helper class to assist with delayed drag operations

Constructor & Destructor Documentation

FDelayedDrag()

FDelayedDrag::FDelayedDrag ( FVector2D  InInitialPosition, FKey  InEffectiveKey  )

inline

Construct this drag helper with an initial posision, and a key (probably mouse button) required for dragging

Member Function Documentation

AttemptDragStart()

bool FDelayedDrag::AttemptDragStart ( const FPointerEvent &  MouseEvent )

inline

Attempt to start a drag from the given mouse event.

ForceDragStart()

void FDelayedDrag::ForceDragStart ( )

inline

Force the state of this helper to be 'dragging'

GetInitialPosition()

const FVector2D & FDelayedDrag::GetInitialPosition ( ) const

inline

Get the initial start position (before any drag has started)

IsDragging()

bool FDelayedDrag::IsDragging ( ) const

inline

Check whether we have initiated a drag or not

SetTriggerScaleFactor()

void FDelayedDrag::SetTriggerScaleFactor ( float  InTriggerScaleFactor )

inline

Assign a new scale factor to apply to the drag trigger distance

Member Data Documentation

bHasInitiatedDrag

bool FDelayedDrag::bHasInitiatedDrag

protected

True where the distance dragged is sufficient to have started a drag

DistanceDragged

float FDelayedDrag::DistanceDragged

protected

The amount we have dragged

EffectiveKey

FKey FDelayedDrag::EffectiveKey

protected

The key that must be pressed to initiate the drag

InitialPosition

FVector2D FDelayedDrag::InitialPosition

protected

The initial position of the drag start

TriggerDistance

float FDelayedDrag::TriggerDistance

protected

The minimum distance that must be moved before the drag initiates.
