LXQt Panel#

Settings are accessible by right clicking on free space on the panel or its plugins (except window buttons in task manager) and can be blocked completely checking the last item to prevent accidental changes or removals of plugins.

Plugins can be configured either by right clicking or by Panel Settings → Plugin → icon "..."

Right click the panel's "Main Menu" or "Fancy Menu" widget and choose Configure → Menu File. The following files belong to LXQt: * lxqt-applications-fm.menu: Used by PCManFM-Qt in menu://Applications; not quite relevant to lxqt-panel. * lxqt-config.menu: used by "Configuration Center"; not relevant to lxqt-panel. * lxqt-applications.menu: The default menu. * lxqt-applications-compact.menu Can be used in both Mainmenu and Fancymenu, in Mainmenu it will generate a two-level layout.

[!Note] lxqt-applications-compact.menu does not display a probable "Wine" category because ~/.config/menus/applications-merged does not match "compact". Renaming it to "compact-merged" will fix that.

LXQt 2.3 and later: * lxqt-panel-applications.menu Default menu for Fancymenu.

For adding a new menu entry, the directory ~/.local/share/applications/ can be opened in PCManFM-Qt and a new desktop entry can be created in it by using Tools → Create Launcher.
For modifying an existing menu entry, the application's .desktop file can be copied from /usr/share/applications/ to ~/.local/share/applications/ and then edited. Changes will not be lost with updates.
For hiding an existing menu entry, the application's .desktop file can be copied from /usr/share/applications/ to ~/.local/share/applications/ and then edited by adding the line NoDisplay=true. Changes will not be lost with updates.

Panel Profiles#

By installing lxqt-panel-profiles different panel configurations can be backuped and restored.

A powerful and versatile plugin which can show outputs from commands as text or image and launch applications.

Plugin Keyboard-Indicator#

It is possible to show country flags instead of the ISO code for the keyboard layout installing iso-flags-svg or iso-flags-png if provided by the distribution in use. An independent set can be found here. The path to the folder containing the flags has to be configured manually, example /usr/share/iso-flags-svg/country-4x3/%1.svg.
