Python 对于 Maya："Object's name is not unique." 从 class 调用对象构建 UI

Question

问题：

在我尝试构建 UI 之前，当我运行脚本时，我没有收到任何语法错误。一切似乎都很好，直到我运行最后两行代码。

我收到以下错误： 错误：运行时错误：文件第 41 行：对象名称 'mst_txtfld_x_value' 不唯一。

我确保在第 8~9 行 deleteUI，所以我假设 textField 是被创建两次。

或者我对类的工作方式有什么不了解的地方吗？我是类的新手，希望能解释一下为什么会出现此错误。

代码：

您忘记了设置 ui 命令的编辑标志。

#ui commands
mc.button(self.move_btn, 
        edit=True, 
        command=partial(self.move_selection))
mc.textField("mst_txtfld_x_value", edit=True,
            enterCommand=partial(self.move_selection))
mc.textField("mst_txtfld_y_value", edit=True,
            enterCommand=partial(self.move_selection))             
mc.textField("mst_txtfld_z_value", edit=True,
            enterCommand=partial(self.move_selection))
