- string getGLStateDump(stateDumpEnums options)
An uncreatable QML type that provides an extension API that can be used to the dump current OpenGL driver state as a string that can be then, for example, be printed on the console log. You can get it by calling Context3D.getExtension with "QTCANVAS3D_gl_state_dump" as parameter.
Typical usage could be something like this:
// Declare the variable to contain the extension var stateDumpExt; . . // After the context has been created from Canvas3D, get the extension stateDumpExt = gl.getExtension("QTCANVAS3D_gl_state_dump"); . . // When you want to print the current GL state with everything enabled // Check that you indeed have a valid extension (for portability) then use it if (stateDumpExt) log("GL STATE DUMP:\n"+stateDumpExt.getGLStateDump(stateDumpExt.DUMP_FULL));

Returns OpenGL driver state with given options as a human readable string that can be printed. Optional paremeter options may contain bitfields masked together from following options:
GLStateDumpExt.DUMP_BASIC_ONLYIncludes only very basic OpenGL state information.
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BITIncludes all vertex attribute array information.
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BUFFERS_BITIncludes size and type from all currently active vertex attribute arrays (including the currently bound element array) to verify that there are actual values in the array.
