horizontal-scrolling - 如何使用触控板/水平滚轮支持横向滚动？

Question

我有一个支持缩放的 SciChartSurface，如下所示：

在常规滚动时缩放 x 轴。
滚动时缩放 y 轴 +CTRL
滚动时平移 x 轴 +Shift

当用户在触控板上水平滚动或使用水平滚轮（拇指轮）时，我还想启用 X 方向的平移。但是，我不知道该怎么做。

这是我一直在使用的扩展 MouseWheelZoomModifier。我可以以某种方式向它发送有关我的滚动行为的信息吗？我可以以某种方式将横向/水平滚动视为Shift+滚动吗？谢谢！

class MouseWheelZoomModifierEx : MouseWheelZoomModifier {
    public override void OnModifierMouseWheel(ModifierMouseArgs e) {
        switch (e.Modifier) {
            case MouseModifier.Ctrl:
                ActionType = ActionType.Zoom;
                XyDirection = XyDirection.YDirection;
                break;
            case MouseModifier.Shift:
                ActionType = ActionType.Pan;
                XyDirection = XyDirection.XDirection;
                break;
            default:
                ActionType = ActionType.Zoom;
                XyDirection = XyDirection.XDirection;
                break;
        }

        // e.Modifier is set to None so that the base implementation of 
        // OnModifierMouseWheel doesn't change ActionType and XyDirection again.
        e.Modifier = MouseModifier.None;
        base.OnModifierMouseWheel(e);
    }
}
