Similarly, you can pass a QString to a function that takes a const char * argument using the qPrintable() macro which returns the given QString as a const char *. This is equivalent to calling <QString>.toLocal8Bit().constData(). Manipulating String Data QString provides the following ...
// action function in a separate thread. A CFRunLoopTimer is used to make sure // the action function is not called before the CFRunLoop is running. // Note that starting with macOS 10.12, the run loop may be stopped when a // window is closed, so we need to put the call to CFRun...

Due to the rules of C++ object destruction, those objects will be destroyed before calling this function (but after that the destructor of the subclass has run), therefore making the OpenGL context current in this function happens too late for their safe disposal. See also makeCurrent. QOpenGL...
An exception that is not caught in the function that has locked the mutex has no way of unlocking the mutex before the exception is passed up the stack to the calling function. QMutexLocker also provides a mutex() member function that returns the mutex on which the QMutexLocker is ...

When control returns to the main event loop, all events that are stored in the queue will be sent using the notify() function. Events are sorted in descending priority order, i.e. events with a high priority are queued before events with a lower priority. The priority can be any integer...
Purely script-defined: A script can both define signal handler functions (effectively "slots written in Qt Script"),andset up the connections that utilize those handlers. For example, a script can define a function that will handle theQLineEdit::returnPressed() signal, and then connect that sign...
