WorldWind Kotlin/earth.worldwind/[web]BasicWorldWindowController

BasicWorldWindowController

open class BasicWorldWindowController(wwd: WorldWindow) : WorldWindowController

This class provides the default window controller for WorldWind for controlling the globe via user interaction.

Constructors

constructor(wwd: WorldWindow)

Properties

fling

val fling: FlingAnimator

Inertial pan animator. Each platform's createFlingScheduler supplies the per-frame clock. The per-frame action dispatches by projection: 2D uses incremental projected-meters math, 3D uses great-circle radians. Picking the right one matters because Mercator metersPerPixel diverges from the 3D radians-on-a-sphere formula away from the equator.

panRecognizer

val panRecognizer: GestureRecognizer

pinchRecognizer

val pinchRecognizer: GestureRecognizer

pivotAnchor

val pivotAnchor: PivotAnchorState

Shared anchor for pinch / rotate / wheel handlers. Lazy because engine may not be initialized yet at controller-construction time.

primaryDragRecognizer

val primaryDragRecognizer: GestureRecognizer

rotationRecognizer

val rotationRecognizer: GestureRecognizer

secondaryDragRecognizer

val secondaryDragRecognizer: GestureRecognizer

tiltRecognizer

val tiltRecognizer: GestureRecognizer

velocitySampler

val velocitySampler: ReleaseVelocitySampler

Trailing-window velocity tracker used to seed fling on gesture release.

Functions

gestureStateChanged

open override fun gestureStateChanged(recognizer: GestureRecognizer)

handleEvent

open override fun handleEvent(event: Event)

release

open override fun release()

Releases any platform resources held by the controller (timers, frame callbacks). Subclasses should override and call super.release() to add their own cleanup (e.g. VC repeat timers).
