Question

我在观看图像方面有MAUI应用。图像使用SKCanvasView。我想增加动物群功能,在窗户上,这些功能将使用 mo轮。然而,我找不到这样做的途径。接近我所期待的东西,似乎就是PinchGesture,但 mo轮 t却被翻译。我发现,有些控制有<条码>点轮式轮./代码>活动,但<条码>SKCanvasView/代码>不是其中之一。我也听到了为这一目的撰写习惯依赖服务和操作人员的情况,但没有实际实例说明这种摩擦。

I have a hunch that this is impossible in MAUI for now (unless I go really low level and tap into Windows APIs), but if someone knows a way how to make this work, I would appreciate it.

You can add the PointerWheelChanged event to the windows platform view of the SKCanvasView. Such as：

在Xaml:

<sk:SKCanvasView x:Name="skview" HeightRequest="300" WidthRequest="300"/>

And in the page s code behind:

    protected override void OnHandlerChanged()
    {
        base.OnHandlerChanged();
#if WINDOWS
            var view = skview.Handler.PlatformView as SkiaSharp.Views.Windows.SKXamlCanvas;
            view.PointerWheelChanged += ( s, e) =>
            {

            };
#endif
      }

我对此进行了测试,并能够探测到SKCanvasView上的 mo轮。
