Maya 2015 Python - 文本字段输入，单选按钮选择在 UI 中不起作用

Question

我正在研究 python 为 Maya 开发工具（目前是 2015 年），但我无法准确理解我应该如何定义要在函数内部使用的变量或 ui 对象。当我尝试运行我的脚本时会弹出很多不同的错误（例如对于这个脚本：# Error: NameError: file line 1: name 'inputTextA' is not defined）

我一遍又一遍地遇到同样的问题，所以我希望有人向我解释我犯了什么样的错误以及将来要研究什么来解决这种麻烦。 （请仅 Python 和 Maya 回答！:)）

下一个脚本保存在maya的脚本路径中，从架子上调用如下：

import uiTestA
reload (uiTestA)
uiTestA

在脚本中，根据您设置的单选按钮（A，B），在按下“执行”按钮后，一个函数应该使用 textField 信息运行。 脚本本身：

# -*- coding: utf-8 -*-

import maya.cmds as cmds

def printStuff (fieldID):
    selObjs=cmds.ls(selection=True)
    print "\n###############################################"
    if ( cmds.radioButtonGrp( radioButtonsA, q=True, select=True )==1 ):
        if len(selObjs)>0:
            typeObj = cmds.textField( fieldID, query=True, text=True )
            if typeObj=="exception":
                print "EXCEPTION [%s] CASE A" % typeObj
            elif typeObj=="":
                cmds.error( "Please input something" )
            else:
                print "NORMAL [%s] CASE A" % typeObj
        else:
            cmds.error( "Please select a group or object in the scene." )
    elif ( cmds.radioButtonGrp( radioButtonsA, q=True, select=True )==2 ):
        typeObj = cmds.textField( fieldID, query=True, text=True )
        if typeObj=="exception":
            print "EXCEPTION [%s] CASE B" % typeObj
        elif typeObj=="":
            cmds.error( "Please input something" )
        else:
            print "NORMAL [%s] CASE B" % typeObj
    print "\n###############################################\n"

winID = "uiTestA"
if cmds.window( winID, exists=True ):
    cmds.deleteUI( winID )
cmds.window ( winID, sizeable=False, width=325, resizeToFitChildren=True )
formLay = cmds.formLayout( numberOfDivisions=100 )

radioButtonsA = cmds.radioButtonGrp( width=325, label='Search in:  ', columnWidth3=(80,158,100), labelArray2=["A", "B"], select=1, numberOfRadioButtons=2 )
explanationA = cmds.text( width=330, label="Input:" )
inputTextA = cmds.textField( width=100 )
selectButton = cmds.button( width=150, label="Execute", command="%s.printStuff(inputTextA)"%__name__)

cmds.formLayout( formLay, edit=True, attachForm=[(radioButtonsA, 'top', 5), (radioButtonsA, 'left', 0), (explanationA, 'top', 30), (inputTextA, 'top', 45), (inputTextA, 'left', 117), (selectButton, 'top', 70), (selectButton, 'left', 92)] )

cmds.showWindow( winID )

我尝试定义一个函数来创建用户界面，例如：

# -*- coding: utf-8 -*-

import maya.cmds as cmds

def printStuff (fieldID):
    selObjs=cmds.ls(selection=True)
    print "\n###############################################"
    if ( cmds.radioButtonGrp( radioButtonsA, q=True, select=True )==1 ):
        if len(selObjs)>0:
            typeObj = cmds.textField( fieldID, query=True, text=True )
            if typeObj=="exception":
                print "EXCEPTION [%s] CASE A" % typeObj
            elif typeObj=="":
                cmds.error( "Please input something" )
            else:
                print "NORMAL [%s] CASE A" % typeObj
        else:
            cmds.error( "Please select a group or object in the scene." )
    elif ( cmds.radioButtonGrp( radioButtonsA, q=True, select=True )==2 ):
        typeObj = cmds.textField( fieldID, query=True, text=True )
        if typeObj=="exception":
            print "EXCEPTION [%s] CASE B" % typeObj
        elif typeObj=="":
            cmds.error( "Please input something" )
        else:
            print "NORMAL [%s] CASE B" % typeObj
    print "\n###############################################\n"

def ui()
    winID = "uiTestA"
    if cmds.window( winID, exists=True ):
        cmds.deleteUI( winID )
    cmds.window ( winID, sizeable=False, width=325, resizeToFitChildren=True )
    formLay = cmds.formLayout( numberOfDivisions=100 )

    radioButtonsA = cmds.radioButtonGrp( width=325, label='Search in:  ', columnWidth3=(80,158,100), labelArray2=["A", "B"], select=1, numberOfRadioButtons=2 )
    explanationA = cmds.text( width=330, label="Input:" )
    inputTextA = cmds.textField( width=100 )
    selectButton = cmds.button( width=150, label="Execute", command="%s.printStuff(inputTextA)"%__name__)

    cmds.formLayout( formLay, edit=True, attachForm=[(radioButtonsA, 'top', 5), (radioButtonsA, 'left', 0), (explanationA, 'top', 30), (inputTextA, 'top', 45), (inputTextA, 'left', 117), (selectButton, 'top', 70), (selectButton, 'left', 92)] )

    cmds.showWindow( winID )

然后从 Maya 的书架上正确调用它；但没有结果。 我对此很陌生，所以请温柔一点！ :) 提前感谢您的时间和帮助！祝你今天过得愉快！ :)

maya ui 总是会出现大问题。这是一个链接，其中包含有关它的所有详细信息： Maya Python - Using data from UI

总而言之，有多种方法可以走：

• 创建字典（最简单）
• 使用 partial 或 lambda 传递变量
• 创建一个类（更高级，简单的 ui 不需要）

=============================================

首先，你不应该写：

selectButton = cmds.button( width=150, label="Execute", command="%s.printStuff(inputTextA)"%__name__)

命令标志不应该是字符串，你必须使用部分或 lambda，即：

from functools import partial

    selectButton = cmds.button( width=150, label="Execute", command=partial(printStuff, name))

=============================================

要在 def 之外查询单选按钮，请像这样使用 dic：

uiDic = {}
uiDic['radioButtonsA'] = cmds.radioButtonGrp( width=325, label='Search in:  ', columnWidth3=(80,158,100), labelArray2=["A", "B"], select=1, numberOfRadioButtons=2 )

# query ===

if ( cmds.radioButtonGrp(uiDic['radioButtonsA'], q=True, select=True )==1 ):

-------- 编辑 ------------ 这是您的脚本的一个工作示例：

import maya.cmds as cmds
from functools import partial

dicUI = {}

def printStuff (fieldID, *args):
    selObjs=cmds.ls(selection=True)
    print "\n###############################################"
    if ( cmds.radioButtonGrp( dicUI['radioButtonsA'], q=True, select=True )==1 ):
        if len(selObjs)>0:
            typeObj = cmds.textField( fieldID, query=True, text=True )
            if typeObj=="exception":
                print "EXCEPTION [%s] CASE A" % typeObj
            elif typeObj=="":
                cmds.error( "Please input something" )
            else:
                print "NORMAL [%s] CASE A" % typeObj
        else:
            cmds.error( "Please select a group or object in the scene." )
    elif ( cmds.radioButtonGrp( dicUI['radioButtonsA'], q=True, select=True )==2 ):
        typeObj = cmds.textField( fieldID, query=True, text=True )
        if typeObj=="exception":
            print "EXCEPTION [%s] CASE B" % typeObj
        elif typeObj=="":
            cmds.error( "Please input something" )
        else:
            print "NORMAL [%s] CASE B" % typeObj
    print "\n###############################################\n"

def ui():
    dicUI['winID'] = "uiTestA"
    if cmds.window( dicUI['winID'], exists=True ):
        cmds.deleteUI( dicUI['winID'] )
    cmds.window ( dicUI['winID'], sizeable=False, width=325, resizeToFitChildren=True )
    formLay = cmds.formLayout( numberOfDivisions=100 )

    dicUI['radioButtonsA'] = cmds.radioButtonGrp( width=325, label='Search in:  ', columnWidth3=(80,158,100), labelArray2=["A", "B"], select=1, numberOfRadioButtons=2 )
    explanationA = cmds.text( width=330, label="Input:" )
    inputTextA = cmds.textField( width=100 )
    selectButton = cmds.button( width=150, label="Execute", command=partial(printStuff, inputTextA))

    cmds.formLayout( formLay, edit=True, attachForm=[(dicUI['radioButtonsA'], 'top', 5), (dicUI['radioButtonsA'], 'left', 0), (explanationA, 'top', 30), (inputTextA, 'top', 45), (inputTextA, 'left', 117), (selectButton, 'top', 70), (selectButton, 'left', 92)] )

    cmds.showWindow( dicUI['winID'] )
