[static] QString QObject::​trUtf8(const char * sourceText, const char * disambiguation = 0, int n = -1)

Returns a translated version of sourceText, or QString::fromUtf8(sourceText) if there is no appropriate version. It is otherwise identical to tr(sourceText, disambiguation, n).

Warning: This method is reentrant only if all translators are installed before calling this method. Installing or removing translators while performing translations is not supported. Doing so will probably result in crashes or other undesirable behavior.

Warning: For portability reasons, we recommend that you use escape sequences for specifying non-ASCII characters in string literals to trUtf8(). For example:

label->setText(tr("F\374r \310lise"));

See also tr(), QCoreApplication::translate(), and Internationalization with Qt.

T qFindChild(const QObject * obj, const QString & name = QString())

This function overloads qFindChildren().

This function is equivalent to obj->findChild<T>(name).

Note: This function was provided as a workaround for MSVC 6 which did not support member template functions. It is advised to use the other form in new code.

See also QObject::findChild().
