    paddings      = 2,
    check_shape   = function(cr, width, height)
        local rs = math.min(width, height)
        cr:move_to( 0  , 0  )
        cr:line_to( rs , 0  )
        cr:move_to( 0  , 0  )
        cr:line_to( 0  , rs )
        cr:move_to( 0  , rs )
        cr:line_to( rs , rs )
        cr:move_to( rs , 0  )
        cr:line_to( rs , rs )
        cr:move_to( 0  , 0  )
        cr:line_to( rs , rs )
        cr:move_to( 0  , rs )

  • signal_name string
  • ... Other arguments
wibox.widget.checkbox:emit_signal (name, ...)
Emit a signal.
  • name string The name of the signal.

wibox.widget.checkbox:connect_signal (name, func)
Connect to a signal.
  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.

This allows the callback function to be garbage collected and automatically disconnects the signal when that happens.

Warning: Only use this function if you really, really, really know what you are doing.

  • name string The name of the signal.
  • func function The callback to call when the signal is emitted.
