Object properties
- 🔗 markup string · 1 signal
-
Set the HTML text of the textbox.
The main difference between text and markup is that markup is able to render a small subset of HTML tags. See the Pango markup) documentation to see what is and isn't valid in this property.
local w = wibox.widget { markup = "This is some <i>text</i>, <b>HTML tags</b> <u>WILL</u> work.", widget = wibox.widget.textbox, }
The wibox.widget.textbox colors are usually set by wrapping into a wibox.container.background widget, but can also be done using the markup:
local w = wibox.widget { markup = "<span background='#ff0000' foreground='#0000ff'>Some</span>".. " nice <span foreground='#00ff00'>colors!</span>", widget = wibox.widget.textbox, }
Constraints:
Default value : self.text
Valid values : The text to set. This can contain pango markup (e.g. <b>bold</b>
). You can usegears.string.escape

- 🔗 font font · 1 signal · 1 theme variable
-
Set a textbox font.
There is multiple valid font string representation. The most precise is XFT. It is also possible to use the family name, followed by the face and size such as
Monospace Bold 10
. This script lists the fonts present on your system:#!/usr/bin/env lua local lgi = require("lgi") local pangocairo = lgi.PangoCairo local font_map = pangocairo.font_map_get_default() for k, v in pairs(font_map:list_families()) do print(v:get_name(), "monospace?: "..tostring(v:is_monospace())) for k2, v2 in ipairs(v:list_faces()) do print(" ".. v2:get_face_name()) end end
Save this script somewhere on your system,
chmod +x
it and run it. It will list something like:Sans monospace?: false Regular Bold Italic Bold Italic
In this case, the font could be
Sans 10
orSans Bold Italic 10
.Here are examples of several font families:
Usage example output:
sans 0 sans NORMAL NORMAL Roboto, Bold 0 Roboto NORMAL NORMAL DejaVu Sans, Oblique 0 DejaVu Sans NORMAL OBLIQUE Noto Mono, Regular 0 Noto Mono NORMAL NORMAL
Usage example:
local pango = require("lgi").Pango local fonts = { "sans", "Roboto, Bold", "DejaVu Sans, Oblique", "Noto Mono, Regular" } for _, font in ipairs(fonts) do local w = wibox.widget { font = font, text = "The quick brown fox jumps over the lazy dog!", widget = wibox.widget.textbox, } -- Use the low level Pango API to validate the font was parsed properly. local desc = pango.FontDescription.from_string(w.font) print( string.format( "%s %d %s %s %s", w.font, desc:get_size(), desc:get_family(), desc:get_variant(), desc:get_style() ) ) end
The font size is a number at the end of the font description string:
for _, font in ipairs { "sans 8", "sans 10", "sans 12", "sans 14" } do local w = wibox.widget { font = font, text = "The quick brown fox jumps over the lazy dog!", widget = wibox.widget.textbox, } end

Object methods
- 🔗 :get_preferred_size (s) -> (number, number)
-
Get the preferred size of a textbox.
This returns the size that the textbox would use if infinite space were available.
Parameters:
Name Type(s) Description s integer or screen The screen on which the textbox will be displayed. Returns:
- number The preferred width.
- number The preferred height.
- 🔗 :get_height_for_width (width, s) -> number
-
Get the preferred height of a textbox at a given width.
This returns the height that the textbox would use when it is limited to the given width.
Parameters:
Name Type(s) Description width number The available width. s integer or screen The screen on which the textbox will be displayed. Returns:
-
number
The needed height.
- 🔗 :get_preferred_size_at_dpi (dpi) -> (number, number)
-
Get the preferred size of a textbox.
This returns the size that the textbox would use if infinite space were available.
Parameters:
Name Type(s) Description dpi number The DPI value to render at. Returns:
- number The preferred width.
- number The preferred height.
- 🔗 :get_height_for_width_at_dpi (width, dpi) -> number
-
Get the preferred height of a textbox at a given width.
This returns the height that the textbox would use when it is limited to the given width.
Parameters:
Name Type(s) Description width number The available width. dpi number The DPI value to render at. Returns:
-
number
The needed height.
- 🔗 :set_markup_silently (text) -> boolean or (boolean, string)
-
Set the text of the textbox.(with
Pango markup).
Parameters:
Name Type(s) Description text string The text to set. This can contain pango markup (e.g. <b>bold</b>
). You can usegears.string.escape
to escape parts of it.Returns:
-
boolean
true
Or
- boolean false
- string Error message explaining why the markup was invalid.
- 🔗 :add_button (button) · Inherited from wibox.widget.base
-
Add a new awful.button to this widget.
Parameters:
Name Type(s) Description button awful.button The button to add. - 🔗 :emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget.base
-
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.
Note that this function has some flaws:
- The signal is only forwarded once the widget tree has been built. This happens after all currently scheduled functions have been executed. Therefore, it will not start to work right away.
- In case the widget is present multiple times in a single widget tree, this function will also forward the signal multiple times (once per upward tree path).
- If the widget is removed from the widget tree, the signal is still forwarded for some time, similar to the first case.
Parameters:
Name Type(s) Description signal_name string ... Other arguments - 🔗 :index (widget, recursive, ...) -> (number, widget, table) · Inherited from wibox.widget.base
-
Get the index of a widget.
Parameters:
Name Type(s) Description widget widget The widget to look for. recursive Optional boolean Recursively check accross the sub-widgets hierarchy. ... Optional widget Additional widgets to add at the end of the sub-widgets hierarchy "path". Returns:
- number The widget index.
- widget The parent widget.
- table The hierarchy path between "self" and "widget".
- 🔗 :connect_signal (name, func) · Inherited from gears.object
-
Connect to a signal.
Usage example output:
In slot [obj] nil nil nil In slot [obj] foo bar 42
Parameters:
Name Type(s) Description name string The name of the signal. func function The callback to call when the signal is emitted. Usage:
local o = gears.object{} -- Function can be attached to signals local function slot(obj, a, b, c) print("In slot", obj, a, b, c) end o:connect_signal("my_signal", slot) -- Emitting can be done without arguments. In that case, the object will be -- implicitly added as an argument. o:emit_signal "my_signal" -- It is also possible to add as many random arguments are required. o:emit_signal("my_signal", "foo", "bar", 42) -- Finally, to allow the object to be garbage collected (the memory freed), it -- is necessary to disconnect the signal or use
weak_connect_signal
o:disconnect_signal("my_signal", slot) -- This time, theslot
wont be called as it is no longer connected. o:emit_signal "my_signal" - 🔗 :weak_connect_signal (name, func) · Inherited from gears.object
-

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.

-
Emit a signal.
Parameters:
Name Type(s) Description 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()
Signals

-
When the widget content changed.
This signal is emitted when the content of the widget changes. The widget will
