QtCreator代码生成器之opencv版本

一、效果图：

1.新建项目

2.配置工程

3. 自动生成的cpp文件

.

4.自动生成的pro文件

二、基本方法

Qt提供了用户自定义Wizards的方法，在Qt的安装路径下：G:\softwareWin8\Qt_free\Tools\QtCreator\share\qtcreator\templates\wizards，是软件自带的向导，参考它的写法，就可以写自己的Wizards.

三、具体步骤

1、在G:\softwareWin8\Qt_free\Tools\QtCreator\share\qtcreator\templates\wizards文件夹下新建文件夹，命名“opencv_wizard”，在新文件夹下，新建一个xml文件，命名为“wizard.xml”（一定要这个名字）。

2、wizard.xml的代码如下

代码比较简单，非常好懂。

<icon>的内容是图标的名字，这个图标需要保存在wizard.xml同路径下。

<files>是需要复制的代码文件，也需要保存在wizard.xml同路径下。

<fields>是自己添加的内容，它会出现在项目配置页中，如上面第2张图。

添加的代码文件可以通过wizard.xml元素的元素名访问它的值，这样通过钩钩叉叉就配置opencv的路径了，不用自己写pro文件了。
