How can I capture maya 3d view with QPixmap?

Question

I make a screen capture script for maya. So, I deal the job with QPixmap class.

I write the script like that.

from PyQt4 import QtCore, QtGui
import sip
import maya.cmds as cmds
import maya.OpenMayaUI as mui

def getMayaWindow():
    ptr = mui.MQtUtil.mainWindow()
    return sip.wrapinstance(long(ptr), QtCore.QObject)

pm = QtGui.QPixmap.grabWindow(getMayaWindow().winId())
pm.save('c:/test.png')

but, it can't grab the 3Dview, so it can't work.

Had the same issue. There is the solution by Nathan Horne which works fine. However, if you want to get the QWidget object that a certain M3dView uses, follow these steps:

import maya.OpenMayaUI as apiUI
from PyQt4 import QtGui, QtCore
import sip

view = apiUI.M3dView.active3dView()
widget_ptr = view.widget()
widget = sip.wrapinstance(long(widget_ptr), QtCore.QObject)
pixmap = QtGui.QPixmap.grabWidget(widget)

As you know, you can then save the pixmap to a file or use it directly for another QWidget. Strangely enough, the result seems a mess (or at least less predictable) and I recommend using Nathan Horne's solution.
