所以我正在尝试制作一个 GUI，允许用户将任何指定的 polyShapes（用复选框选择）构建到他们需要的任何属性（在滑块中设置）。此外，当每个复选框被选中时，它会取消选择其他框并将用户不需要的某些属性变灰。

我正在努力使用定义每个复选框被选中时会发生什么的功能。选择复选框后，按下属性和创建按钮，该过程正常工作（我希望结果），但我会收到以下错误，除了最后一个复选框外，所有其他复选框：

RuntimeError: Object 'window1|formLayout46|checkBox3' not found. #

我被告知这是一个错误，因为函数运行在旧/以前版本的窗口中，并且将滑块等作为参数传递给函数将修复错误。但是，这并不能解决问题，当然我不能在创建复选框之前将它们作为参数传递，如下面的代码所示。它也没有解释为什么最后一个复选框（checkBoxCylinder）工作得很好——我假设这工作得很好，因为在它之前一切都已经完成了。

任何关于此事的建议/解释都将不胜感激，因为我现在觉得我在绕圈子。为下面的长代码道歉，我不能使用摘录，因为它们都链接在一起！！

您可能不想为此使用全局，这会使您的状态管理复杂化。执行此操作的通常“正确”方法（故意使用引号）是将 GUI 包装在一个类中并将所有状态存储在该类中，因此很容易知道所有这些都将相同的状态数据连接到相同的小部件。除了使代码更整洁之外，它还可以打开同一个对话框的多个副本（例如，如果您需要那种东西，每个对象一个）。

这是一个非常简单的例子。由于所有小部件（至少是您关心的所有小部件）都包含在对话框的“自我”中，因此在响应按钮单击时获取所需信息很简单

import pymel.core as pm

class SliderDialog(object):

     def __init__(self):
        self.SomeSpecialData = "Hello world"
        self.Window = pm.window(width = 300)
        with pm.columnLayout():
           self.XSlider = pm.floatSliderGrp(label  = 'x', field = True)
           self.YSlider = pm.floatSliderGrp(label  = 'y', field = True)
           self.ZSlider = pm.floatSliderGrp(label  = 'z', field = True)
           with pm.rowLayout(nc= 2):
               self.Cancel = pm.button("cancel", width = 150, command = self.cancel_button)
               self.Go = pm.button("go", width = 150, c=self.go_button)
     def show(self):
         self.Window.show()

     def go_button(self, *_):
         # your actual work goes here
         print "Special Data = ", self.SomeSpecialData 
         x, y, z = self.XSlider.getValue(), self.YSlider.getValue(),  self.ZSlider.getValue()          

         print "do something with XYZ (%i, %i, %i)" % (x, y, z)

     def cancel_button(self, *_):
         print "cancelling"
         pm.deleteUI(self.Window)

SliderDialog().show()

这是有关将 python 函数挂钩到 Maya GUI 回调的详细参考。
