◆ qt_setWindowTitle_helperHelper()

QString qt_setWindowTitle_helperHelper ( const QString &  title,

Returns a modified window title with the [*] place holder replaced according to the rules described in QWidget::setWindowTitle.

This function assumes that "[*]" can be quoted by another "[*]", so it will replace two place holders by one and a single last one by either "*" or nothing depending on the modified flag.

Warning
This function is not part of the public interface.
