qt5base-lts/examples/widgets/mainwindows/application/mainwindow.h
Friedemann Kleint b693900da5 Polish the widgets/mainwindows/application example.
- Introduce Qt 5 signals & slot syntax
- Use QCommandLineParser to obtain file arguments
- Merge MainWindow::createMenus()/createQToolBars()
  into MainWindow::createActions(), removing the need
  to store the actions as member variables.
  Use QMenu::addAction() for brevity.
- Use QIcon::fromTheme() to obtain system icons and use
  resource icons as fallback.
- Rewrite settings code to use
  QWidget::saveGeometry(), Widget::restoreGeometry() since
  saving size and position does not work well with multiple
  screens. Query the available size when determining
  the initial size instead of using hard-coded values
  for High-DPI screens.
- Fix minor issues in code, use multi-argument version
  of QString::arg(), QDir::toNativeSeparators() to
  present file paths to the user.
- Fix snippet references accordingly.
