在 Maya 的时间滑块中设置高亮范围

Question

使用以下方法很容易在时间滑块中获取高亮范围：

import maya.cmds as cmds
import maya.mel as mel

aTimeSlider = mel.eval('$tmpVar=$gPlayBackSlider')
timeRange = cmds.timeControl(aTimeSlider, q=True, rangeArray=True)

同样可以使用

访问 Qt 小部件

from maya import mel
from maya import OpenMayaUI as omui 

try:
  from PySide2.QtCore import * 
  from PySide2.QtGui import * 
  from PySide2.QtWidgets import *
  from PySide2 import __version__
  from shiboken2 import wrapInstance 
except ImportError:
  from PySide.QtCore import * 
  from PySide.QtGui import * 
  from PySide import __version__
  from shiboken import wrapInstance 

widgetStr = mel.eval( 'string $tempString = $gPlayBackSlider' )    
ptr = omui.MQtUtil.findControl( widgetStr )
timeSliderWidget = wrapInstance(long(ptr), QWidget)

但是，以编程方式设置时间滑块的突出显示范围似乎几乎是不可能的。真的没有办法吗？

我在想可能有一种方法可以修改 Qt 小部件，但我迷失了这个。

这似乎是与相同的问题。

为了完整起见，也将其张贴在这里：这是最大的 hacky 解决方法。使用 Qt Mouse 按下、移动和释放事件来模拟鼠标在时间滑块小部件上的行为以获得它 select。

在代码中，我临时更改了时间滑块范围以最大化屏幕 space 我想要单击的帧。
