qt5options — Common commandline options for all applications based on the Qt toolkit


Qt application [-style= style / -style style] [-stylesheet= stylesheet / -stylesheet stylesheet] [-widgetcount] [-reverse] [-qmljsdebugger= port] [-platform platformName[:options]] [-platformpluginpath path] [-platformtheme platformTheme] [-plugin plugin] [-qwindowgeometry geometry] [-qwindowicon icon] [-qwindowtitle title] [-reverse] [-session session] [-display hostname:screen_number] [-geometry geometry] [-dialogs= [xp|none]] [-fontengine= freetype] [-h, --help and -? on Windows] [-v --version]


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