Conversation
Add GestureDeviceSelector (matches an exact device name, a device class and subclass, or a device class), nested Options types for Pan/Tap/LongPress gesture detectors with GetDefaultOptions, SetDeviceOptions, TryGetDeviceOptions and ClearDeviceOptions, Gesture.DeviceName, and per-device recognition thresholds (PanThresholds, TapThresholds, LongPressThresholds, PinchThresholds, RotationThresholds) exposed through GestureOptions.Instance. Also expose TapGestureDetector.ReceiveAllTapEvents / IsReceiveAllTapEventsEnabled. All new members are [EditorBrowsable(EditorBrowsableState.Never)] until ACR. Adds a DeviceGestureOptionsSample demonstrating the feature: a PanGestureDetector and a TapGestureDetector recognize gestures differently for mouse vs. touch, using detector-local Options (mouse pans restricted to roughly horizontal drags, both allow a double tap) and GestureOptions.Instance per-device thresholds (mouse needs a longer drag before a pan starts and a faster second tap for a double tap than the touch defaults). A touchscreen is not required to see the effect. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
