M3dView::viewport()
函数原型：
viewport (unsigned int &x, unsigned int &y, unsigned int &width, unsigned int &height)
在maya python api中使用方式如下：
import maya.OpenMayaUI as OpenMayaUIimport maya.OpenMayaRender as OpenMayaRender
import maya.cmds as cmds
import maya.OpenMaya as OpenMaya
view = OpenMayaUI.M3dView.active3dView()
a_util = OpenMaya.MScriptUtil()
a_ptr = a_util.asUintPtr()
b_util = OpenMaya.MScriptUtil()
b_ptr = b_util.asUintPtr()
width_util = OpenMaya.MScriptUtil()
width_ptr = width_util.asUintPtr()
height_util = OpenMaya.MScriptUtil()
height_ptr = height_util.asUintPtr()
view.viewport(a_ptr,b_ptr,width_ptr,height_ptr)
print a_util.getUint(a_ptr),b_util.getUint(b_ptr),width_util.getUint(width_ptr),height_util.getUint(height_ptr)
