当用户保存文件时,我希望在保存之前进行检查。如果检查失败,那么它就不会保存。我使用了mSceneMessage和kBeforeSaveCheck,但我不知道如何在失败时自定义弹出消息。这可能吗?
import maya.OpenMaya as om
import maya.cmds as cmds
def func(retCode, clientData):
objExist = cmds.objExists('pSphere1')
om.MScriptUtil.setBool(retCode, (not objExist) ) # Cancel save if there's pSphere1 in the scene
cb_id = om.MSceneMessage.addCheckCallback(om.MSceneMessage.kBeforeSaveCheck, func)
现在显示
用户提供的回调取消了文件操作。

我对这个问题有点迟钝,但今天我需要类似的东西,所以我想我会做出回应。我无法决定是否在一般情况下推荐这个,但严格来说, 可以使用displayString
命令在Maya界面中更改相当数量的静态字符串。简单的部分是,你知道你正在寻找的字符串
import maya.cmds as cmds
message = u"File operation cancelled by user supplied callback."
keys = cmds.displayString("_", q=True, keys=True)
for k in keys:
value = cmds.displayString(k, q=True, value=True)
if value == message:
print("Found matching displayString: {}".format(k))
在Maya 2015上运行此功能可查找超过30000个已注册的显示字符串,并返回单个匹配键:s_TfileIOStrings.rFileOpCancelledByUser
。似乎对我很有希望。
这是您修改的初始代码,用于更改显示字符串:
import maya.OpenMaya as om
import maya.cmds as cmds
def func(retCode, clientData):
"""Cancel save if there is a pSphere1 in the scene"""
objExist = cmds.objExists('pSphere1')
string_key = "s_TfileIOStrings.rFileOpCancelledByUser"
string_default = "File operation cancelled by user supplied callback."
string_error = "There is a pSphere1 node in your scene"
message = string_error if objExist else string_default
cmds.displayString(string_key, replace=True, value=message)
om.MScriptUtil.setBool(retCode, (not objExist))
cb_id = om.MSceneMessage.addCheckCallback(om.MSceneMessage.kBeforeSaveCheck, func)
