GLStateDumpExt QML Type▲
-
Import Statement: import QtCanvas3D 1.1
-
Since: QtCanvas3D 1.0
Detailed Description▲
Deprecated in Qt 5.12. An uncreatable QML type that provides an extension API that can be used to 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)

string getGLStateDump(stateDumpEnums options)▲
* Deprecated in Qt 5.12. * 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_ONLY Includes only very basic OpenGL state information. *
-
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BIT Includes all vertex attribute array * information. *
-
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BUFFERS_BIT Includes 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. *
-
GLStateDumpExt.DUMP_FULL Includes everything. *
* This command is handled synchronously.
