aqui esta erro error: C2061: syntax error : identifier 'CaseSensitive'

Hum.... estranho. Fiz um Ctrl+C Ctrl+V num arquivo .h, e não deu erro algum.

Testei no QtCreator 2.6.2, com o Qt 4.8.3 (Linux).

Que versão do Qt você está usando? O erro dá no .h ou no .cpp? Está usando o QtCreator, ou apenas o qmake para o build?

Talvez o log de compilação ajude.

Esqueci que só o .h não compila. :)

Você está usando o Qt::CaseSentive, que é o valor do enum

@ enum CaseSensitivity {
CaseInsensitive,
CaseSensitive
};
@

No seu código, o correto é:

@
signals:

void findNext(const QString &str, Qt::CaseSensitivity cs);
void findPrevious(const QString &str ,Qt::CaseSensitivity cs);
