Constructor & Destructor Documentation

◆ QSystemLocale()

QSystemLocale::QSystemLocale ( )

Constructs a QSystemLocale object.

The constructor will automatically install this object as the system locale. It and the destructor maintain a stack of system locales, with the most-recently-created instance (that hasn't yet been deleted) used as the system locale. This is only intended as a way to let a platform plugin install its own system locale, overriding what might otherwise be provided for its class of platform (as Android does, differing from Linux), and to let tests transiently override the system or plugin-supplied one. As such, there should not be diverse threads creating and destroying QSystemLocale instances concurrently, so no attempt is made at thread-safety in managing the stack.

This constructor also resets the flag that'll prompt QLocale::system() to re-initialize its data, so that instantiating a QSystemLocale (even transiently) triggers a refresh of the system locale's data. This is exploited by some test code.

◆ ~QSystemLocale()

QSystemLocale::~QSystemLocale ( )
virtual

Deletes the object.
