OPTIONS

       The following options apply to all Qt(TM) applications:

       -style= style / -style style
           Set the application GUI style. Possible values depend on the system configuration. If
           Qt(TM) is compiled with additional styles or has additional styles as plugins these
           will be available to the -style command line option.

       -stylesheet= stylesheet / -stylesheet stylesheet
           Set the application styleSheet. The value must be a path to a file that contains the
           Style Sheet.

       -widgetcount
           Print debug message at the end about number of widgets left undestroyed and maximum
           number of widgets existed at the same time.

       -reverse
           Set the application's layout direction to Qt::RightToLeft. This option is intended to
           aid debugging and should not be used in production. The default value is automatically
           detected from the user's locale (see also QLocale::textDirection()).

       -qmljsdebugger= port
           Activate the QML/JS debugger with a specified port. The value must be of format
           port:1234[,block], where block is optional and will make the application wait until a
           debugger connects to it.

       -platform platformName[:options]
           Specify the Qt(TM) Platform Abstraction (QPA) plugin.

       -platformpluginpath path
           Specify the path to platform plugins.

       -platformtheme platformTheme
           Specify the platform theme.

       -plugin plugin
           Specify additional plugins to load. The argument may appear multiple times.

       -qwindowgeometry geometry
           Specify the window geometry for the main window using the X11-syntax. For example:
           -qwindowgeometry 100x100+50+50

       -qwindowicon icon
           Set the default window icon.

       -qwindowtitle title
           Set the title of the first window.

       -session session
           Restore the application from an earlier session.

       -display hostname:screen_number
           Switch displays on X11. Overrides the DISPLAY environment variable.

       -geometry geometry
           Specify the window geometry for the main window on X11. For example: -geometry
           100x100+50+50

       -dialogs= [xp|none]
           Only available for the Windows® platform. XP uses native style dialogs and none
           disables them.

       -fontengine= freetype
           Use the FreeType font engine.

       -h, --help and -? on Windows®
           Print all options and the application description.

       -v --version
           Display the version string of the application.
