Class wibox.widget.checkbox
A boolean display widget.
If necessary, themes can implement custom shape:
wibox.widget { checked = true, color = beautiful.bg_normal, 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 ) cr:line_to( rs , 0 ) end, check_border_color = '#ff0000', check_color = '#00000000', check_border_width = 1, widget = wibox.widget.checkbox }
Usage:
wibox.widget { checked = true, color = beautiful.bg_normal, paddings = 2, shape = gears.shape.circle, widget = wibox.widget.checkbox }

Set/get a widget’s buttons.
- _buttons The table of buttons that should bind to the widget.
- wibox.widget.checkbox:emit_signal_recursive (signal_name, ...)

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

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.
