在做QT自定义组件开发的时候，拷贝代码，再批改太繁琐了，所以想着能不能主动生成下根底组件，于是有了主动生成组件的想法。一个根本的组件是长这个样子：
.pri QT子工程配置文件*.cpp,*.h, 组件内容*plugin.cpp,*plugin.h，组件插件化配置，次要用于qt designer里进行利落一开始的想法是应用bat脚本(因为外面应用了中文，所以此文件须要保留为ansi格局，保留成UTF-8的化执行会有问题)批处理，运行后先拷贝cpushbutton组件目录，而后遍历此目录，对文件进行重命名
@echo offset target=DialogButtonBoxset cTarget=C%target%set qTarget=Q%target%set dir="%cd%/cpushbutton - 正本"set lowerCTarget=%cTarget%for %%i in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do call set lowerCTarget=%%lowerCTarget:%%i=%%i%%set upperCTarget=%cTarget%for %%i in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do call set upperCTarget=%%upperCTarget:%%i=%%i%%ren %dir% %lowerCTarget%set newDir="%cd%/%lowerCTarget%"for /r %newDir% %%i in (*.*) do ( if "%%~xi"==".pri" ( ren %%i "%lowerCTarget%%%~xi" )else ( echo "%%~ni"| findstr "plugin" >nul &&( ren %%i "%lowerCTarget%plugin%%~xi" )||( ren %%i "%lowerCTarget%%%~xi" ) ))重命名后须要的是文件内容替换，整顿了一下后大略是这么些数据，为了不便，我在bat里主动生成了对应内容，在QT creator里间接拷贝过来，执行五次替换即可
echo CPUSHBUTTON-%upperCTarget% > 1.txtecho QPushButton-%qTarget% >> 1.txtecho CPushButton-%cTarget% >> 1.txtecho cpushbutton-%lowerCTarget% >> 1.txtecho cPushButton-c%target% >> 1.txt感觉还是繁琐，就想着这五次替换能不能一部到位，惋惜的是QT creator不能间接执行定义的脚本，间接做五次替换，所以萌发了本人写个程序呗，做文件替换。
一、定义demo
demo.pri
HEADERS += $$PWD/{FILENAME}.hHEADERS += $$PWD/{FILENAME}plugin.hSOURCES += $$PWD/{FILENAME}.cppSOURCES += $$PWD/{FILENAME}plugin.cppdemo.h
