+ \class QGraphicsFrameCaptureRenderDoc
+ \internal
+ \brief The QGraphicsFrameCaptureRenderDoc class provides a way to capture a record of draw calls
+ for different graphics APIs.
+ \since 6.6
+ \inmodule QtGui
+
+ For applications that render using graphics APIs like Vulkan or OpenGL, it would be
+ convenient to have a way to check the draw calls done by the application. Specially
+ for applications that make a large amount of draw calls and the output is different
+ from what is expected.
+
+ This class acts as a wrapper over \l {https://renderdoc.org/}{RenderDoc} that allows
+ applications to capture a rendered frame either programmatically, by clicking a key
+ on the keyboard or both. The captured frame could be viewed later using RenderDoc GUI.
+
+ Read the \l {https://renderdoc.org/docs/index.html} {RenderDoc Documentation}
+ for more information.
+
+ \section1 API device handle
+
+ The functions that capture a frame like QGraphicsFrameCaptureRenderDoc::startCaptureFrame takes a device
+ pointer as argument. This pointer is unique for each graphics API and is associated
+ with the window that will be captured. This pointer has a default value of \c nullptr.
+ If no value is passed to the function the underlying API will try to find the device to
+ use, but it is not guaranteed specially in a multi-window applications.
+
+ For OpenGL, the pointer should be the OpenGL context on the platform OpenGL is being
+ used. For example, on Windows it should be \c HGLRC.
+
+ For Vulkan, the pointer should point to the dispatch table within the \c VkInstance.
+*/
+
+
+
+/*!
+ Creates a new object of this class. The constructor will load RenderDoc library
+ from the default path.
+
+ Only one instance of RenderDoc library is loaded at runtime which means creating
+ several instances of this class will not affect the RenderDoc initialization.
