/* 宏参数说明
* classname:类名,例如DLineEdit
* accessiblename:accessible唯一标识,需保证唯一性[getAccessibleName函数处理],优先使用QObject::setAccessibleName值
* accessibletype:即QAccessible::Role,表示标识控件的类型
* classobj:QObject指针
* accessdescription:accessible描述内容,考虑到暂时用不到,目前都默认为空,有需要可自行设计接口
*
* 部分创建宏说明
* FUNC_CREATE:创建构造函数
* FUNC_PRESS:创建Press接口
* FUNC_SHOWMENU:创建右键菜单接口
* FUNC_PRESS_SHOWMENU:上两者的综合
* FUNC_RECT:实现rect接口
* FUNC_TEXT:实现text接口
* USE_ACCESSIBLE:对传入的类型设置其accessible功能
* USE_ACCESSIBLE_BY_OBJECTNAME:同上,[指定objectname]---适用同一个类，但objectname不同的情况
*
* 设置为指定类型的Accessible控件宏
* SET_BUTTON_ACCESSIBLE_PRESS_SHOWMENU:button类型,添加press和showmenu功能
* SET_BUTTON_ACCESSIBLE_SHOWMENU:button类型,添加showmenu功能
* SET_BUTTON_ACCESSIBLE:button类型,添加press功能
* SET_LABEL_ACCESSIBLE:label类型,用于标签控件
* SET_FORM_ACCESSIBLE:form类型,用于widget控件
* SET_SLIDER_ACCESSIBLE:slider类型,用于滑块控件
