用Qt编写Maya插件
先贴个代码，待会解释。
#
# Renaming Tool by Clement Chaudat - 2014 v1.1.0
#
# CONSTANTS IN TEXTFIELDS
# Multiple constants with right-click on textField:
# - OldName: good for prefix/suffix
# - ObjectType
# - ParentName
#
# INCREMENT: "###" or "%3d"
# Right-click on textField then "Set Start/Step" for
# start number and step value for indent.
#
# RENAME USING REGEXP:
# example : "end$" will replace "end" at the end of the name
# "^start" will replace "start" at the beginning of the name
