在RenderControl项目的RenderForm上使用SharpDX

Question

我目前正试图在RenderForm之上实现一个按钮，但是使用RenderControl后，RenderForm就变成了一个没有任何东西的白色画布。

我尝试将所有内容卸载到另一个类中，并使用相同的RenderTarget，但这也不起作用。我现在使用的唯一解决方法是一个自定义MouseMove代码，它读取鼠标指针所在的位置，然后更改自定义ButtonState枚举，以决定应该在按钮的边界上呈现哪些图像。这很慢，在按钮的状态更改为MouseOver之间会有延迟。

编辑:使用MonoGame代替。SharpDX太不稳定了，对任何事情来说都不稳定。

我也能读取和转换C#代码。

主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

        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

延迟是因为相同的线程用于呈现和更改按钮状态。尝试在按钮工作中使用不同的线程。

简单地尝试多线程以避免延迟。
