OPTIONS

The following options apply to all Qt™ applications:

-style= style / -style style
    Set the application GUI style. Possible values depend on the system configuration. If Qt™ 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™ 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.
