You can directly access a QGLWidget whose context is shared with other Viewport 2.0 resources. This is useful in the case when your plug-in creates OpenGL resources for it's own QGLWidget and you want it to share the plug-in's OpenGL resources with Viewport 2.0.
import PySide2 import PySide2.QtOpenGL import PySide2.QtWidgets import shiboken2 #Get the property from the application (as a QWidget) widget = PySide2.QtWidgets.QApplication.instance().property("mayaSharedQGLWidget") #Get the raw C++ pointer ptr =shiboken2.getCppPointer(widget)[0] #Downcast to QGLWidget glWidget = shiboken2.wrapInstance(ptr, PySide2.QtOpenGL.QGLWidget) #Print the format of the current rendering context print (glWidget.format())
QVariant v = qApp->property("mayaSharedQGLWidget"); if (v.isValid()) { QGLWidget glWidget = dynamic_cast<QGLWidget*>(v.value<QWidget*>()); }
