Tray Module
|
|
|
|
|
===========
|
2023-04-03 01:59:56 +00:00
|
|
|
.. poly-setting:: type = internal/tray
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
.. versionadded:: 3.7.0
|
|
|
|
|
|
|
|
|
|
The tray module displays system tray application icons on the bar.
|
|
|
|
|
|
|
|
|
|
This module is a bit different from the other modules.
|
|
|
|
|
The tray icons (also called clients) are individual windows managed by their
|
|
|
|
|
respective application (e.g. the Dropbox tray icon is created and managed by
|
|
|
|
|
the Dropbox application).
|
|
|
|
|
Polybar is only responsible for embedding the windows in the bar and
|
|
|
|
|
positioning them correctly.
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
|
|
|
|
|
Only a single instance of this module can be active at the same time (across
|
|
|
|
|
all polybar instances).
|
|
|
|
|
|
|
|
|
|
The way the `system tray protocol <systray-spec_>`_ works, at most one tray
|
|
|
|
|
can exist at any time.
|
|
|
|
|
Polybar will produce a warning if additional tray instances are created.
|
|
|
|
|
|
|
|
|
|
For transparent background colors, the tray will use pseudo-transparency, true
|
|
|
|
|
transparency is not possible for the tray icons.

Formats
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
The module only has a single format:
|
|
|
|
|
|
2023-04-02 23:37:26 +00:00
|
|
|
.. poly-setting:: format

|
|
|
|
|
|
|
|
:type: |type-format|
|
|
|
|
|
:tags: ``<tray>``: Shows tray icons
|
|
|
|
|
:default: ``<tray>``
|
|

.. poly-setting:: tray-padding
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
Space added before and after each tray icon
|
|
|
|
|
|
|
|
|
|
:type: |type-extent|, non-negative
|
|
|
|
|
:default: ``0px``

2023-04-02 23:37:26 +00:00
|
|

.. poly-setting:: tray-size
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
Size of individual tray icons
|
|
|
|
|
|
2023-04-03 01:59:56 +00:00
|
|
|
:type: |type-pwo|, relative to bar height, non-negative
|
2023-04-01 20:51:17 +00:00
|
|
|
:default: 66%
|
|
|
|
|
|
2023-04-02 23:37:26 +00:00
|
|
|
.. poly-setting:: tray-background
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
Background color of tray icons
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
This only affects the color of the individual icons and not the space in
|
2023-04-03 01:59:56 +00:00
|
|
|
between, changing this setting to anything else than the bar background
|
|
|
|
|
will likely not look good.
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
:type: |type-color|
|
|
|
|
|
:default: ``${root.background}``
|
|
|
|
|
|
2023-04-02 23:37:26 +00:00
|
|
|
.. poly-setting:: tray-foreground
|
2023-04-01 20:51:17 +00:00

|
|
2023-04-03 01:59:56 +00:00

|
Tray icon color
|
2023-04-01 20:51:17 +00:00
|
|
|
|
2023-04-03 01:59:56 +00:00
|
|
|
This serves as a hint to the tray icon application for which color to use for
|
|
|
|
|
the icon.
|
2023-04-01 20:51:17 +00:00
|
|
|
|
|
|
|
|
This is not guaranteed to have any effect (likely only in GTK3) because it
|
|
|
|
|
targets a non-standard part of the `system tray protocol <systray-spec_>`_ by
|
|
|
|
|
setting the ``_NET_SYSTEM_TRAY_COLORS`` atom on the tray window.
|
|
|
|
|
|
|
|
|
|
:type: |type-color|

:default: ``${tray-foreground}``
