C＃表单上的OpenGL视图 [英] OpenGL view on C# Form

问题描述

如何在Windows窗体中显示一个过滤窗口？

How to display a glut window inside Windows Form?

glutCreateWindow（Example）创建另一个表单

glutCreateWindow("Example") create another form,

glutCreateSubWindow（hwnd，0，0， 100），其中hwnd在C＃中处理我的主窗口窗体，我得到一个AccessViolation异常。

glutCreateSubWindow(hwnd, 0, 0, 100, 100), where hwnd is handle to my main Window Form in C#, i get an AccessViolation Exception.

Glut程序在一个C ++ DLL中。我的应用程序是在C＃WPF。我需要在我的C＃表单中显示glut视图

The Glut program is in a C++ DLL. My application is on C# WPF. I need to display glut view at my C# Form

C ++代码：

extern "C"
    {
        __declspec(dllexport) int InitGlut(int hwnd, int top, int left, int width, int height)
        {
            glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
            glutInitWindowPosition(top,left);
            glutInitWindowSize(320,320);
            //glutCreateWindow("Example");
            glutCreateSubWindow(hwnd, top, left, width, height);
            glutDisplayFunc(renderScene);
            glutMainLoop();
            return 0;
        }
    }

C＃代码：

const string pathToDll = "../../../Release/MyDLL.dll";
[DllImport(pathToDll)]
public static extern int InitGlut(IntPtr hwnd, int top, int left, int width, int height);

private void Window_Loaded(object sender, RoutedEventArgs e)
{
     IntPtr hwnd = new WindowInteropHelper(Application.Current.MainWindow).Handle;
     InitGlut(hwnd, 0, 0, 100, 100);
}

推荐答案

看起来你正在托管一个WPF表单中的Win32对象。是的，这需要解决方法。

Looks like you're hosting a Win32 object in a WPF form. Yes, this requires workarounds.

您是否看过MSDN上的WPF和Win32互操作指南？

Have you seen the WPF and Win32 Interoperation guide on MSDN?

您还需要查看HwndHost类：

You'll need to check out the HwndHost class, too:
