Question

我想用python编写一个UI窗口，以下是我的代码，函数运行正常，但是有一个问题，当我在textScrollList中选择一个项目时，它应该调用内部函数＆＃39;更新（）＆＃39;并突出显示场景中的相应对象。但是，无法正确选择对象，并显示如下错误消息：

＆＃34;对象＆＃39; alertWindow | formLayout164 | textScrollList27＆＃39;没找到。＆＃34;

我认为这是因为内部函数update（）无法访问外部函数中的变量tsl，是否有人知道如何修改我的代码？

def alertWindow():
    if(cmds.window('mainWindow', q =True, exists = True,)):
        cmds.deleteUI('mainWindow')
    UI = cmds.window('mainWindow', title = 'Alert!', maximizeButton = False,   minimizeButton = False, resizeToFitChildren = True, widthHeight = (250, 300), sizeable = False)
    myForm=cmds.formLayout(  )

    txt = cmds.text(label = 'Please check the following objects :')
    tsl = cmds.textScrollList(width = 200, height = 200, enable = True, allowMultiSelection = True, selectCommand = 'update()') 

    count = len(obj)
    for i in range(count):
        cmds.textScrollList(tsl, edit=True, append = obj[i])

    delete = cmds.button(label = 'delete', width = 100, command = 'remove()')
    clz = cmds.button(label = 'Close', width = 100, command = 'cmds.deleteUI("mainWindow")')

    cmds.formLayout(myForm, edit = True, attachForm = [(txt, 'top', 20),(txt, 'left', 65),(tsl, 'left', 25),(tsl, 'top', 50),(delete,'bottom',10),(delete,'left',15),(clz,'bottom',10),(clz,'right',20)])
    cmds.showWindow(UI)

    def update():
        cmds.select(cmds.textScrollList(tsl, q=True, selectItem = True))

    def remove():
        cmds.DeleteHistory()
        cmds.textScrollList(tsl, edit=True, removeItem = cmds.ls(sl=True))

Answer 1

您可以尝试在代码顶部使用全局变量“global tsl”。这不是最美丽的，但是有效：）

您需要先定义内部函数，然后只引用它们，不需要为command=使用字符串：

def alertWindow(obj):
    def update():
        cmds.select(cmds.textScrollList(tsl, q=True, selectItem = True))

    def remove():
        cmds.DeleteHistory()
        cmds.textScrollList(tsl, edit=True, removeItem = cmds.ls(sl=True))

    if(cmds.window('mainWindow', q =True, exists = True,)):
        cmds.deleteUI('mainWindow')
    UI = cmds.window('mainWindow', title = 'Alert!', maximizeButton = False,   minimizeButton = False, resizeToFitChildren = True, widthHeight = (250, 300), sizeable = False)
    myForm=cmds.formLayout(  )

    txt = cmds.text(label = 'Please check the following objects :')
    tsl = cmds.textScrollList(width = 200, height = 200, enable = True, allowMultiSelection = True, selectCommand = update) 

    count = len(obj)
    for i in range(count):
        cmds.textScrollList(tsl, edit=True, append = obj[i])

    delete = cmds.button(label = 'delete', width = 100, command = remove)
    clz = cmds.button(label = 'Close', width = 100, command = 'cmds.deleteUI("mainWindow")')

    cmds.formLayout(myForm, edit = True, attachForm = [(txt, 'top', 20),(txt, 'left', 65),(tsl, 'left', 25),(tsl, 'top', 50),(delete,'bottom',10),(delete,'left',15),(clz,'bottom',10),(clz,'right',20)])
    cmds.showWindow(UI)




cmds.polyCube()
alertWindow(['pCube1'])

你也可以使用一个类来保持事物的状态。
