## Detailed Description
该QGLFramebufferObject类封装了一个OpenGL帧缓冲区对象。
该QGLFramebufferObject类封装了一个OpenGL帧缓冲区对象,由定义`GL_EXT_framebuffer_object`扩展名。此外,它提供了一种渲染表面,可以涂在用[QPainter](qpainter.html),呈现给使用本地GL调用,或两者兼而有之。这种表面可以在自己的GL绘图代码的约束,并作为一个普通的纹理。默认情况下, QGLFramebufferObject类生成一个2D GL纹理(使用`GL_TEXTURE_2D`目标) ,它是用来作为内部渲染对象。
**It is important to have a current GL context when creating a QGLFramebufferObject, otherwise initialization will fail.**
OpenGL的帧缓冲对象和pbuffers的(见[QGLPixelBuffer](qglpixelbuffer.html))都可以用来渲染到屏幕外表面,但也有许多与使用帧缓冲区对象而不是pbuffers的优点:
1. 一个帧缓冲对象不需要一个单独的渲染上下文,因此切换渲染目标时不会发生上下文切换。存在参与切换目标的开销,但一般它比上下文切换到一个pbuffer的便宜。
2. 渲染到动态纹理(即渲染到纹理功能)适用于所有平台。没有必要做明确的副本从一个渲染缓冲区调用到一个纹理,因为有必要对那些不支持系统`render_texture`扩展名。
3. 它可以连接多个渲染缓冲区(或纹理对象)到相同的帧缓冲区对象,并呈现给所有的人都没有做上下文切换。
4. OpenGL的帧缓冲扩展是一个纯粹的GL扩展,不依赖于系统WGL ,鳄鱼卹,或GLX部分。这使得使用帧缓冲对象更便于携带。
当使用一个[QPainter](qpainter.html)画一个QGLFramebufferObject的QGLFramebufferObject与创建时要注意[CombinedDepthStencil](qglframebufferobject.html#Attachment-enum)附件[QPainter](qpainter.html)要能正确呈现。请注意,您需要使用绘图时创建每像素多于一个样本的QGLFramebufferObject对原语进行反锯齿[QPainter](qpainter.html)。要创建一个多重采样帧缓冲区对象,你应该使用采取QGLFramebufferObject参数的构造函数之一,并设置QGLFramebufferObject.samples ()属性设置为一个非零值。
当画到QGLFramebufferObject使用[QPainter](qpainter.html),目前GL上下文的状态将由绘图引擎进行修改,以反映其需求。应用程序不应依赖于GL状态被重置到其原始条件,特别是目前的着色器程序,吉尔口中,纹理单元和绘图模式。
对于多重采样帧缓冲对象的颜色渲染在创建缓冲区,否则创建具有指定目标的质感纹理。色彩渲染缓冲器或纹理将具有指定的内部格式,并且将被绑定到`GL_COLOR_ATTACHMENT0`附件中的帧缓冲区对象。
如果你想使用一个帧缓冲对象启用多重采样作为纹理,你首先需要从它复制到使用QGLContext.blitFramebuffer ( )一个普通帧缓冲区对象。
### Threading
由于Qt的4.8的,有可能用来绘制成QGLFramebufferObject一个[QPainter](qpainter.html)在一个单独的线程。需要注意的是OpenGL的2.0或OpenGL ES 2.0的是需要这种合作。此外, X11下,有必要设置[Qt.AA_X11InitThreads](qt.html#ApplicationAttribute-enum)应用属性。

## Type Documentation
```
QGLFramebufferObject.Attachment
```
该枚举类型是用来配置连接到帧缓冲对象被创建时,它的深度和模板缓冲区。
| Constant | Value | Description |
| --- | --- | --- |
| `QGLFramebufferObject.NoAttachment` | `0` | 没有附件被添加到帧缓冲区对象。需要注意的是渲染到帧缓冲区对象,没有任何深度或模板缓冲区时, OpenGL的深度和模板测试将无法正常工作。这是默认值。 |
| `QGLFramebufferObject.CombinedDepthStencil` | `1` | 如果`GL_EXT_packed_depth_stencil`扩展目前,结合深度和模板缓存连接。如果扩展名不存在,只有深度缓冲区连接。 |
| `QGLFramebufferObject.Depth` | `2` | 深度缓冲连接到帧缓冲区对象。 |
这个枚举被引入或修改的Qt 4.3 。

## Method Documentation
```
QGLFramebufferObject.__init__ (self, QSize size, int target = GL_TEXTURE_2D)
```
构造一个OpenGL帧缓冲区对象和一个2D GL纹理结合到大小的缓冲_size_。纹理被绑定到`GL_COLOR_ATTACHMENT0`针对在帧缓冲对象。
该_target_参数用于指定总帐质感目标。默认的目标是`GL_TEXTURE_2D`。请记住,`GL_TEXTURE_2D`纹理必须有2宽度和高度(如256×512个)的功率,除非你正在使用的OpenGL 2.0或更高版本。
默认情况下,没有深度和模板缓冲区连接。这种行为可以使用重载的构造函数之一进行切换。
默认的内部纹理格式是`GL_RGBA8`对于桌面OpenGL ,和`GL_RGBA`为OpenGL / ES 。
你有一个当前的GL上下文创建时设置是很重要的[QGLFramebufferObject](qglframebufferobject.html),否则初始化将失败。
