Question

我试图为maya创建一个脚本，它基本上将快速选择集作为列表中的索引。

我已经使用已存在的按钮存储和加载信息，但我希望用户能够在默认选择集数量不足时生成新按钮。

我目前有一个生成新按钮的按钮。如果只生成一个按钮，它可以正常工作。

我的第一个问题：如果您生成第二个按钮，则第一个生成的按钮会使用与第二个生成按钮相同的列表索引。

e.g。我创建了一个新按钮（按钮4）。它可以毫无问题地存储和加载选择。我创建了另一个新按钮（按钮5）。现在按钮4将存储和加载，就像它是按钮5一样，按钮5本身也是如此。

我的第二个问题：如果您已经存储了选择，则无法创建新按钮。

到目前为止我的代码是：

import maya.cmds as mc

favsWindowName = 'favsWindow'
numButtons = 4

def favsWindowUI():
    if mc.window(favsWindowName, exists=True):
        mc.deleteUI(favsWindowName, wnd=True)
    mc.window(favsWindowName, title="Favourites", resizeToFitChildren=True, bgc=(0.20, 0.50, 0.50), s=True)
    mc.rowColumnLayout(nr=1)
    mc.button("newSet", label="New Selection Set", c=("newButton()"))
    mc.rowColumnLayout(nr=2)
    mc.button("Load1", label="Load Slot 1", w=200, c=("Load(1)"))
    mc.button("Sel1", label="Select Slot 1", w=200, c=("Sel(1)"))
    mc.button("Load2", label="Load Slot 2", w=200, c=("Load(2)"))
    mc.button("Sel2", label="Select Slot 2", w=200, c=("Sel(2)"))
    mc.button("Load3", label="Load Slot 3", w=200, c=("Load(3)"))
    mc.button("Sel3", label="Select Slot 3", w=200, c=("Sel(3)"))
    mc.showWindow()

selList = []

def Load(favNum):
    try:
        # if a selection has already been loaded for this button, replace it.
        selList[favNum-1] = mc.ls(sl=True)
    except IndexError:
        try:
            #if the previous index exists
            if selList[favNum-2] > 0:
                # if a selection has not yet been loaded for this button, create it.
                selList.append(mc.ls(sl=True))
        except IndexError:
            # if the previous index doesn't exist 'cause this is the first entry
            if favNum == 1:
                selList.append(mc.ls(sl=True))
            else:
                #if the previous index doesn't exist, raise an error.
                mc.error("Load the previous selection first!")


def Sel(favNum):
    try:
        # if a selection has been loaded for this button, select it.
        mc.select(selList[favNum-1], r=True)
    except IndexError:
        # if no selection has been loaded for this button, raise an error.
        mc.error("No selection loaded.")

def newButton():
    #generate a new button set using the next available index.
    global numButtons
    mc.button("Load"+str(numButtons), label="Load Slot "+str(numButtons), w=200, c=("Load(numButtons-1)"))
    mc.button("Sel"+str(numButtons), label="Select Slot "+str(numButtons), w=200, c=("Sel(numButtons-1)"))
    numButtons += 1

favsWindowUI()

我也不确定为什么使用生成的按钮我需要在newButton函数中使用Load(numButtons-1)而不是Load(numButtons) ...但它似乎可以解决问题。

如果有人有类似的问题，我会发布我们（我和学校的一些朋友）想出来的解决方案。使用partial解决了使用相同索引的所有新生成按钮的问题。另一个问题（加载选择后无法生成新按钮）是由于没有设置新按钮的父级。我们给了rowColumnLayout一个名称，并使用setParent maya命令将其设置为父级。要在上下文中查看，请参阅下面的代码。

import maya.cmds as mc
from functools import partial

favsWindowName = 'favsWindow'

def favsWindowUI():
    if mc.window(favsWindowName, exists=True):
        mc.deleteUI(favsWindowName, wnd=True)
    mc.window(favsWindowName, title="Favourites", resizeToFitChildren=True, bgc=(0.20, 0.50, 0.50), s=True)
    mc.rowColumnLayout(nr=2)
    mc.textFieldGrp('btnName', tx='new button name')
    mc.button("newSet", label="New selection Set", c=(newButton))
    mc.rowColumnLayout('selectionLayout', nc=2)
    mc.showWindow()

selList = {}

def load(favNum, *args):
    # Load the selection into the dictionary entry
    selList[favNum] = mc.ls(sl=True)


def sel(favNum, *args):
    try:
        # if a selection has been loaded for this button, select it.
        mc.select(selList[favNum], r=True)
    except IndexError:
        # if no selection has been loaded for this button, raise an error.
        mc.error("No selection loaded.")


def newButton(*args):
    buttonName = mc.textFieldGrp('btnName', q=True, tx=True)
    mc.setParent('selectionLayout')
    if buttonName != 'new button name':
        if mc.button("load"+str(buttonName), exists=True, q=True):
            mc.error("A selection set named %s already exists." % buttonName)
        mc.button("load"+str(buttonName), label="Load Slot "+str(buttonName), w=200, c=(partial(load,buttonName)))
        mc.button("sel"+str(buttonName), label="Select Slot "+str(buttonName), w=200, c=(partial(sel,buttonName)))
        mc.textFieldGrp('btnName', tx='new button name', e=True)
    else:
        mc.error("Rename the button first.")


favsWindowUI()
