使用Qt与DirectX？ [英] Using Qt with DirectX?

问题描述

我的选项到底是什么？我有程序，我需要写在 OpenGL 和 DirectX ，而且我想对OpenGL使用 Qt ，而不必为我的任务的DirectX组件重新实现一半我的程序。

我看过Google，我发现有人抱怨< a href =http://en.wikipedia.org/wiki/Microsoft%5FDirect3D> Direct3D 是Qt的依赖，人们谈论以类似QGLWidget的方式实现QD3DWidget子类QWidget，但是没有人谈到如何实现它或任何例子。

我需要帮助。我想知道是否可能？我需要做什么才能使它工作？

   - >创建一个QWidget 
  - >覆盖paintEngine（）方法，不执行任何操作，只返回NULL 
  - >将HWND分配给widget-> winId（）
 
 #ifdef USE_QTGUI 
 QApplication a（argc，argv）; 
 CD3DWidget wndw; wndw.show（）; wndw.resize（1280,960）; 
 hWnd = wndw.winId（）; 
 #else 
 hWnd = CreateAppWindow（name，300,300）; 
 #endif 
 
 // CD3DWidget类只包含以下定义
 CD3DWidget :: CD3DWidget（QWidget * parent）：QWidget（parent）{} 
 QPaintEngine * CD3DWidget :: paintEngine（）{return NULL; } 
  

感谢您，

What exactly are my options? I have programs I need to write in OpenGL and DirectX, and I'd like to use Qt for OpenGL, and not have to re-implement half my program for the DirectX components of my task.

I've looked on Google and I have found references to people complaining about Direct3D being a dependency of Qt, and people talking about implementing QD3DWidget sub-classing QWidget in a similar fashion to QGLWidget, yet nobody talked about how to implement it or where any examples are.

I need help. I want to know if it is possible? What would I need to do to get it working? Has it been done before?

解决方案

its pretty straightforward than I thought,

-> Create a QWidget
-> Override paintEngine() method, does nothing, just returns NULL
-> Assign HWND to widget->winId()

    #ifdef USE_QTGUI
        QApplication a(argc, argv);
        CD3DWidget wndw;    wndw.show();    wndw.resize(1280,960);
        hWnd = wndw.winId();
    #else
        hWnd = CreateAppWindow(name,300,300);
    #endif

       //CD3DWidget class contains only the following definitions
    CD3DWidget::CD3DWidget(QWidget * parent):QWidget(parent){      }
    QPaintEngine *CD3DWidget::paintEngine (){          return NULL;        }
