Question

使用以下方法很容易在时间滑块中获得高亮度范围：

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不可能。真的没办法吗？

我在想，可能有一种方法可以修改Qt小部件，但我在这个小部件上丢失了。

这是我尝试以编程方式设置的突出显示范围。

这似乎是与this question相同的问题。

我posted a hacky workaround there as an answer.

出于完整性考虑，也将其张贴在此处：这是最大的黑客解决方法。使用Qt鼠标按下，移动和释放事件，以模仿时间滑块小部件上的鼠标行为以使其选择。

在代码中，我暂时更改了时间滑块范围，以最大化要单击的帧的屏幕空间。
