Detailed Description

Abstract base of a main function in Qt console application with a event loop.

The class declaration MyMainFunction.h could look like:

class MyMainFunction : public Mdt::AbstractConsoleApplicationMainFunction
{
 Q_OBJECT

 public:

  explicit MyMainFunction(QObject* parent = nullptr);
  int runMain() override;
};

Example of the implementation in MyMainFunction.cpp:

int MyMainFunction::runMain()
{
  qDebug() << "My main ...";
}

Finaly, in main.cpp:

QCoreApplication app(argc, argv);

// This will call runMain() once the event loop started
MyMainFunction mainImpl;

return app.exec();

Member Function Documentation

void Mdt::AbstractConsoleApplicationMainFunction::aboutToQuit ( )

virtualslot

Cleanup code.

If some cleanup has to be done before the application exists, this function can be implemented. See QCoreApplication documentation to know why this is a recommanded way to do cleanup.

This default implementation does nothing.

QStringList Mdt::AbstractConsoleApplicationMainFunction::getArguments ( )

static

Returns the list of command-line arguments.

Returns QCoreApplication::arguments(). As stated in QCoreApplication documentation, this method is slow, so the result should be stored in a variable if accessed many times (this is wy it is prefixed with get here)

Precondition

A instance of a QCoreApplication (or one of its derivate) must exist.
