   This is a simple "Hello world" example:

   It contains only the bare minimum you need
   to get a Qt application up and running.

/*!
   The whole application is contained within
   the \c main() function:

   \quotefromfile examples/main.cpp

   \skipto main
   \printuntil app(argc, argv)

   First we create a QApplication object using
   the \c argc and \c argv parameters.

   \skipto QPushButton
   \printuntil resize

   Then we create a QPushButton, and give it a reasonable
   size using the QWidget::resize() function.

/*!
   There has to be exactly one QApplication object
   in every GUI application that uses Qt.

   \quotefromfile examples/main.cpp

   \printline QApplication

   This line includes the QApplication class
   definition. QApplication manages various
   application-wide resources, such as the
   default font and cursor.

   \printline QPushButton

   This line includes the QPushButton class
   definition. The QPushButton widget provides a command
   button.

   \printline main

   The main function...

   \skipto closeEvent
   \printuntil /^\}/

   Close events are sent to widgets that the users want to
   close, usually by clicking \c File|Exit or by clicking
   the \c X title bar button. By reimplementing the event
   handler, we can intercept attempts to close the
   application.
