Maya Python 第七章 使用Maya命令创建基本工具 7.1

7.2 基本GUI命令

在GUI元素名称前添加其姓名或工作室的首字母作为前缀。

import maya.cmds as cmdscmds.deleteUI(win,window = True)
win = cmds.window('ar_optionsWindow',title = 'My First Window',widthHeight = (546,350))
cmds.showWindow(win)

7.3 构建窗基类

class AR_OptionsWindow(object):def __init__(self):self.window = 'ar_optionWindow'self.title = 'Options Window'self.size = (546,350)def create(self):if cmds.window(self.window,exists = True):cmds.deleteUI(self.window,window = True)self.window = cmds.window(self.window,title = self.title,widthHeight = self.size)cmds.showWindow()      testWindow = AR_OptionsWindow()
testWindow.create()        

class AR_OptionsWindow(object):def __init__(self):self.window = 'ar_optionWindow'self.title = 'Options Window'self.size = (546,350)      def commonMenu(self):self.editMenu = cmds.menu(label = 'Edit')self.editMenuSave = cmds.menuItem(label = 'Save Settings')self.editMenuReset = cmds.menuItem(label = 'Restet Settings'        )self.editMenuDiv = cmds.menuItem(d = True)self.editMenuRadio = cmds.radioMenuItemCollection()self.editMenuTool = cmds.menuItem(label = 'As Tool',radioButton = True,#enable = self.supportsToolAction           )self.editMenuTool = cmds.menuItem(label = 'As Action',radioButton = True,# enable = self.supportsToolAction           )self.helpMenu = cmds.menu(label = 'Help')self.helpMenuItem = cmds.menuItem(label = 'Help on %s'%self.title)def create(self):if cmds.window(self.window,exists = True):cmds.deleteUI(self.window,window= True)self.window = cmds.window(self.window,title = self.title,widthHeight = self.size,menuBar  = True)self.commonMenu()cmds.showWindow()testWindow = AR_OptionsWindow()
testWindow.create()        

对GUI对象执行命令

使用functools模块

from functools import partial
import maya.cmds as cmdsclass LocatorWindow(object):def __init__(self):self.win = cmds.window('ar_locSample',widthHeight=(100, 100),menuBar=True)self.menu = cmds.menu(label='Make Locators')for i in range(5):cmds.menuItem(l='Make %i' % (i + 1),command=partial(self.makeLocCmd, i + 1))cmds.showWindow()def makeLocCmd(self, numLocators, *args):locs = []for i in range(numLocators):locs.append(cmds.spaceLocator(p=[-(numLocators + 1) * 0.5 + i + 1, 0, 0])[0])cmds.select(locs)win = LocatorWindow()
