Signals

widget::layout_changed
When the layout (size) change. This signal is emitted when the previous results of :layout() and :fit() are no longer valid. Unless this signal is emitted, :layout() and :fit() must return the same result when called with the same arguments.

See also:

widget::redraw_needed
When the widget content changed. This signal is emitted when the content of the widget changes. The widget will be redrawn, it is not re-layouted. Put differently, it is assumed that :layout() and :fit() would still return the same results as before.

Methods

wibox.widget.systray:set_base_size (size)
Set the size of a single icon. If this is set to nil, then the size is picked dynamically based on the available space. Otherwise, any single icon has a size of sizexsize.

wibox.widget.systray:set_screen (s)
Set the screen that the systray should be displayed on. This can either be a screen, in which case the systray will be displayed on exactly that screen, or the string "primary", in which case it will be visible on the primary screen. The default value is “primary”.
  • s screen or "primary" The screen to display on.
wibox.widget.systray:index (widget[, recursive[, ...]])
Get a widex index.
  • widget The widget to look for
  • recursive Also check sub-widgets (optional)
  • ... Aditional widgets to add at the end of the "path" (optional)

Returns:

  1. The index
  2. The parent layout
  3. The path between "self" and "widget"
wibox.widget.systray:get_all_children ()
Get all direct and indirect children widgets. This will scan all containers recursively to find widgets Warning: This method it prone to stack overflow id the widget, or any of its children, contain (directly or indirectly) itself.

Returns:

    table The children
wibox.widget.systray:setup (args)
Set a declarative widget hierarchy description. See The declarative layout system

Set/get a widget’s buttons.
  • _buttons The table of buttons that should bind to the widget.
wibox.widget.systray:emit_signal_recursive (signal_name, ...)
Emit a signal and ensure all parent widgets in the hierarchies also forward the signal. This is useful to track signals when there is a dynamic set of containers and layouts wrapping the widget.
  • signal_name string
  • ... Other arguments
wibox.widget.systray:disconnect_signal (name, func)
Disconnect to a signal.
  • name string The name of the signal
  • func function The callback that should be disconnected
wibox.widget.systray:emit_signal (name, ...)
Emit a signal.
  • name string The name of the signal
  • ... Extra arguments for the callback functions. Each connected function receives the object as first argument and then any extra arguments that are given to emit_signal()
wibox.widget.systray: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
wibox.widget.systray:weak_connect_signal (name, func)
Connect to a signal weakly. 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
