Remarks

This processor has the LOWEST priority and serves as the fallback when no element is hit. It handles:

The hit target types this processor handles (bitmask). Use bitwise OR to handle multiple types: HitTargetType.Node | HitTargetType.Group

public override HitTargetType HandledTypes { get; }

Display name for debugging.

public override string Name { get; }

Priority for checking this processor. Higher = checked first.

public override int Priority { get; }

Handles pointer pressed on an element this processor is responsible for.

public override InputProcessorResult HandlePointerPressed(InputStateContext context, GraphHitTestResult hit, PointerPressedEventArgs e)

context InputStateContext: The input state context.
hit GraphHitTestResult: The hit test result (guaranteed to be a type from HandledTypes).
e PointerPressedEventArgs: The Avalonia pointer event.

InputProcessorResult: Result indicating whether handled and any state transition.
