以下成员源于类 QGlobalStatic 被弃用。 提供它们是为使旧源代码能继续工作。强烈建议不要在新代码中使用它们。
(deprecated)
QGlobalStatic::Type *
|
operator() () |
This function is deprecated. We strongly advise against using it in new code.
This function returns the address of the contents of this global static. If the contents have not yet been created, they will be created thread-safely by this function. If the contents have already been destroyed, this function will return a null pointer.
此函数相当于 operator Type * (). It is provided for compatibility with the private Q_GLOBAL_STATIC implementation that existed in Qt 4.x and 5.0. New code should avoid using it and should instead treat the object as a smart pointer.
