示例1: AddGestureRecognizer

{
var gesture = new GestureRecognizer() {
AutoProcessInertia = true,
GestureSettings = GestureSettings.Drag | GestureSettings.CrossSlide,
CrossSlideHorizontally = true,
CrossSlideThresholds = new CrossSlideThresholds { SpeedBumpEnd = 30 }
};
Point lastDragLocation;
var lastDragTime = DateTime.Now;
gesture.Dragging += (sender, args) => {
switch (args.DraggingState) {
case DraggingState.Started:
lastDragLocation = args.Position;
lastDragTime = DateTime.Now;
break;
case DraggingState.Continuing: {
if (swipeDisplayed) {
SwipeHelp.FadeOut();
swipeDisplayed = false;
}
var delta = args.Position.X - lastDragLocation.X;
var time = DateTime.Now.Subtract(lastDragTime).TotalSeconds;
if (Math.Abs(delta) > 30 && time > 0) {
var velocity = delta / time;
lastDragLocation = args.Position;
lastDragTime = DateTime.Now;
Model.Zoomed(velocity);
}
break;
}
}
};
gesture.CrossSliding += (sender, args) => {

var velocity = delta / time;
lastDragLocation = args.Position;
lastDragTime = DateTime.Now;
Model.Zoomed(velocity);
}
break;
}
}
};
GraphView.PointerPressed += (sender, args) => {
