下面是一个通用过程,根据INI文件中的资源改变界面语言(仅Caption和Hint属性)
参数一:为一Component,一般为TForm,此过程将循环列举其子Component并查找是否具有相关属性,
有的话则从INI文件读取信息并设置属性
参数二:为INI文件全名
//引用TypInfo单元
//声明的资源,默认的,防止变量出现空值
resourcestring
S_Menu = 'Menu';
S_AppName = 'Window View Tool';
S_Null = '(Null)';
S_About = '&About...';
S_Warning = 'Warning';
S_Confirm = 'Confirm';
S_Error = 'Error';
S_Information = 'Information';
//声明的常量
const
SCaption = 'Caption';
SHint = 'Hint';
SIniAppName = 'Window View Tools';
SIniLanguage = 'Language';
SLanguageName = 'LanguageName';
