在 SharpDX 项目的 RenderForm 上使用 RenderControl

Question

我目前正在尝试在 RenderForm 上实现一个按钮，但是在使用 RenderControl 后，RenderForm 变成了白色的 canvas，没有任何东西。

我尝试将所有内容卸载到另一个 class 并使用相同的 RenderTarget，但效果不佳。我现在使用的唯一解决方法是自定义 MouseMove 代码，它读取鼠标指针的位置，然后更改自定义 ButtonState 枚举，该枚举决定应在按钮的边界内呈现哪些图像。这很慢，并且在按钮状态更改为 MouseOver.

之间有延迟

编辑：改为使用 MonoGame。 SharpDX 太不稳定了。

P.S。我也可以阅读和转换 C# 代码。

主要 RenderForm 的代码：

Imports SharpDX
Imports SharpDX.Direct2D1
Imports SharpDX.Direct3D
Imports SharpDX.Direct3D11
Imports SharpDX.DirectWrite
Imports SharpDX.DXGI
Imports SharpDX.IO
Imports SharpDX.WIC
Imports SharpDX.Windows
Imports Device = SharpDX.Direct3D11.Device
Imports FactoryD2D = SharpDX.Direct2D1.Factory
Imports FactoryDXGI = SharpDX.DXGI.Factory1
Imports FactoryDW = SharpDX.DirectWrite.Factory
Imports PixelFormat = SharpDX.Direct2D1.PixelFormat
Imports Bitmap = SharpDX.Direct2D1.Bitmap
Imports PointD = SharpDX.Point
Imports Point = System.Drawing.Point
Imports Font = System.Drawing.Font

            .DpiY = DPI.Width

        End With
        RenderTarget = New RenderTarget(Factory, BackBuffer, RenderTargetProp)
    End Using

    SwapChain.GetParent(Of FactoryDXGI)().MakeWindowAssociation(Handle, WindowAssociationFlags.IgnoreAltEnter)

    With RenderTarget
        .AntialiasMode = AntialiasMode.PerPrimitive
        .TextAntialiasMode = TextAntialiasMode.Cleartype
    End With

    RenderLoop.Run(Me, AddressOf DrawCanvas)

    Controls.Add(XButton1)


    RenderTarget.Dispose()
    SwapChain.Dispose()
    Device.Dispose()

End Sub

延迟是因为同一个线程用于呈现和更改按钮状态。尝试为您的按钮工作使用不同的线程。

简单尝试多线程避免延迟。
