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.

-platformtheme platformTheme

Specify the platform theme.

-plugin plugin
