Program qlua accepts the same command line options and arguments as the stand-alone Lua interpreter lua. It also accepts all the Qt command line options as well as a few specific options. 

Usage: qlua [options] [script ]
The lua options are:
  -e stat       execute string 'stat'
  -l name       require library 'name'
  -i            enter interactive mode after executing 'script'
  -v            show version information
  --            stop handling options
  -             execute stdin and stop handling options
The specific qlua options are:
  -ide          run the qlua integrated environment
  -onethread    run lua in the main thread
  -nographics   disable all the graphical capabilities
The most important Qt options are:
  -style s      set the application gui style 's'
  -session s    restore gui session 's'
  -display d    set the X display (default is $DISPLAY)
  -geometry g   set the main window size and position
  -title s      set the main window title to 's'
  ...           see the Qt documentation for more options

Option -nographics initializes the Qt library for a text-only application. This can be handy when executing scripts because it avoids unnecessary overhead.

Option -onethread runs the Lua interpreter in the main thread instead of starting a dedicated thread. As a consequence, while Lua is running, graphical are not handled, windows are not painted, timers are not honored, etc., unless the Lua program calls qt.doevents() frequently enough. This is not the normal mode of operation of qlua but this can be useful for debugging purposes.
