如何显示/隐藏项目（？）在使用python的maya上的活动视图中？

Question

现在我知道如何隐藏活动视口上的所有nurbs曲线。但是我怎么能同时对视窗上显示菜单上的所有项目做同样的事情，比如相机，操纵器，栅格…等等？在

我想我需要使用for循环，但我需要一些指导。谢谢您。在

import maya.cmds as cmds

actView = cmds.getPanel(wf=True)

if cmds.modelEditor(actView, q=True, nurbsCurves=True) == 1:
    cmds.modelEditor(actView, e=True, nurbsCurves=False)

Answer 1

下面是一种隐藏一切的方法：

actView = cmds.getPanel(wf=True) # actView='modelPanel4'
# list the flag we use to hide, not that alo hide nearly everything
hide_attrs = ['alo', 'manipulators', 'grid', 'hud', 'hos', 'sel']
# value is used to make visible or to hide (0 is for hiding)
value = 0
# flags is used to create a dictionary that will be used in the command to do : manipulators = 0
flags = { i : value for i in hide_attrs }
# the double star unpack a python dictionnary the key = value, i.e in this case : alo = 0, hud = 0....
cmds.modelEditor(actView, e=1, **flags)

如果你想更具体一点，你可以为可见属性构建另一个字典

但如果我是你，我会把它封装成一个定义：

def set_actviewVis(value, attrs=list):
    actView = cmds.getPanel(wf=True) # actView='modelPanel4'    
    flags = { i : value for i in attrs }
    cmds.modelEditor(actView, e=1, **flags)

hide_attrs = ['alo', 'manipulators', 'grid', 'hud', 'hos']
set_actviewVis(0, hide_attrs)
vis_attrs = ['sel']
set_actviewVis(1, vis_attrs)
