//Start the event loop. Block the current function call, but the event loop can still run. //This is not going to run down to the front slot, calling loop.. After quitting, we will continue to go down loop.exec(
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 ...
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...
Normal widgets and modal widgets cannot be accessed before the popup widget is closed. Only other popup widgets may be opened when a popup widget is shown. The popup widgets are organized in a stack. This function returns the active popup widget at the top of the stack. See also active...

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...

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...
If stackSize is zero, the operating system or runtime will choose a default value. Otherwise, the thread's stack size will be the value provided (which may be rounded up or down). On most operating systems, the amount of memory allocated to serve the stack will initially be smaller than...
\warning If you override this function, you must ensure all threads that process events stop doing so before your application object begins destruction. This includes threads started by other libraries that you may be using, but does not apply to Qt's own threads. \sa QObject::event(), ...
