Module: awful.widget.taglist
Taglist widget module for awful.
Here is a more advanced example of how to extent the taglist. It provides:
- mouse "hover" color
- an extra index field
- a powerline look and feel
s.mytaglist = awful.widget.taglist { screen = s, filter = awful.widget.taglist.filter.all, style = { shape = gears.shape.powerline }, layout = { spacing = -12, spacing_widget = { color = "#dddddd", shape = gears.shape.powerline, widget = wibox.widget.separator, }, layout = wibox.layout.fixed.horizontal }, widget_template = { { { { { { id = "index_role", widget = wibox.widget.textbox, }, margins = 4, widget = wibox.container.margin, }, bg = "#dddddd", shape = gears.shape.circle, widget = wibox.container.background, }, { { id = "icon_role", widget = wibox.widget.imagebox, }, margins = 2, widget = wibox.container.margin, }, { id = "text_role", widget = wibox.widget.textbox, }, layout = wibox.layout.fixed.horizontal, }, left = 18, right = 18, widget = wibox.container.margin }, id = "background_role", widget = wibox.container.background, -- Add support for hover colors and an index label create_callback = function(self, c3, index, objects) --luacheck: no unused args self:get_children_by_id("index_role")[1].markup = "<b> "..c3.index.." </b>" self:connect_signal("mouse::enter", function() if self.bg ~= "#ff0000" then self.backup = self.bg self.has_backup = true end self.bg = "#ff0000" end) self:connect_signal("mouse::leave", function() if self.has_backup then self.bg = self.backup end end) end, update_callback = function(self, c3, index, objects) --luacheck: no unused args self:get_children_by_id("index_role")[1].markup = "<b> "..c3.index.." </b>" end, }, buttons = taglist_buttons }
As demonstrated in the example above, there are a few "shortcuts" to avoid
re-inventing the wheel. By setting the predefined roles as widget id
s,
awful.widget.common will do most of the work to update the values
automatically. All of them are optional. The supported roles are:
icon_role
: A wibox.widget.imageboxtext_role
: A wibox.widget.textboxbackground_role
: A wibox.container.backgroundtext_margin_role
: A wibox.container.marginicon_margin_role
: A wibox.container.margin
awful.widget.common also has 2 callbacks to give more control over the widget:
create_callback
: Called once after the widget instance is createdupdate_callback
: Called every time the data is refreshed
Both callback have the same parameters:
self
: The widget instance (widget).t
: The tag (tag)index
: The widget position in the list (number)tags
: The list of tag, in order (table)

Constructors
- awful.widget.taglist (args, filter, buttons, style[, update_function[, base_widget]])

Create a new taglist widget. The last two arguments (updatefunction
and layout) serve to customize the layout of the taglist (eg. to
make it vertical). For that, you will need to copy the
awful.widget.common.listupdate function, make your changes to it
and pass it as update_function here. Also change the layout if the
default is not what you want.

Object methods
- :setup {[args]} · Inherited from wibox.widget
-
Set a declarative widget hierarchy description.
See The declarative layout system
Parameters:
- args An array containing the widgets disposition
- :add_button (button) · Inherited from wibox.widget
-
Add a new awful.button to this widget.
Parameters:
- button awful.button The button to add.
- :emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget
-
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.
Parameters:
- signal_name string
- ... Other arguments
- :emit_signal (name, ...) · Inherited from gears.object
-
Emit a signal.
Parameters:
- 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().
- :connect_signal (name, func) · Inherited from gears.object
-
Connect to a signal.
Parameters:
- name string The name of the signal.
- func function The callback to call when the signal is emitted.
- :weak_connect_signal (name, func) · Inherited from gears.object
-
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.
Parameters:
- name string The name of the signal.
- func function The callback to call when the signal is emitted.
Signals
- widget::layout_changed · Inherited from wibox.widget
-
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 · Inherited from wibox.widget
-
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.See also:
