本文将带你了解Maya教程之用Qt编写Maya插件，希望本文对大家学Maya有所帮助

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# import reimport   functoolsimport maya.cmds as cmdsfrom
