=Window Title Bar Theming=
<!--T:2-->
'''LXQt''' is a free and open source lightweight Qt desktop environment that was formed from the merger of the [[Install Desktop Environments#LXDE|LXDE]] and Razor-qt projects. It is focused on being a classic desktop with a modern look and feel. The official website for LXQt can be accessed [https://lxqt-project.org/ here].


The window title bars are drawn onto your screen by the window manager you use. The default window manager of LXQt is Openbox.


The Openbox Configuration Manager can be opened: Start Menu --> Settings --> Openbox Configuration Manager
<!--T:3-->
[[File: Lxqt-de-18.png|left|600px]]
<div style="clear: both"></div>




If you lack the Openbox Configuration Manager, please install it:
=Installation= <!--T:4-->


sudo pacman -S obconf
<!--T:5-->
Instructions for installing LXQt can be found on the [[Install_Desktop_Environments#LXQt|Install Desktop Environments]] page.




Or better, install the qt version of obconf included in repolxqt:
=Window Managers= <!--T:6-->
LXQt is designed to be used with any window manager and does not provide one by its own.


sudo pacman -S obconf-qt-git


But if you've not installed LXQt from the install media you first need to enable repolxqt, or install the AUR package:
==KWin== <!--T:7-->


yaourt -S obconf-qt-git
<!--T:8-->
See article [[LXQt_with_kwin]]




Then please choose your preferred window title bar theme in Openbox Configuration Manager .
=Configuration= <!--T:9-->


Additional themes can be downloaded. Examples:
<!--T:10-->
LXQt provides the '''lxqt-config''' (LXQt Settings) application for configuration.


sudo pacman -S menda-themes-dark
==Global Keyboard Shortcuts== <!--T:11-->
Global shortcuts can be configured by the '''lxqt-config-globalkeyshortcuts''' application (LXQt settings -> Global Shortcuts):
    <Screenshot TBD>
{{BoxDanger|warning|Mapping the Super_L/Super_R keys (<Meta> without a second key) can lead to unexpected behaviour and is not recommended!}}


sudo pacman -S menda-themes
<!--T:12-->
{{BoxInfo|note|Some window manager (kwin, openbox, etc.) specific shortcuts are not configurable by LXQt (e.g. "Alt+Tab" for the task switcher). Those are configured by the window manager.}}


yaourt -S mediterraneannight-theme


=Theming= <!--T:13-->


Alternatively, follow this guide to install a more modern window manager with higher hardware resources: [[LXQt with kwin]]
<!--T:14-->
In can take a few steps to get everything matching on LXQt since it is a collection of things.  There are a few different things that are separately themed:
* GTK2/GTK3
* QT
* Openbox
* LXQt panels


=Window Content Theming=


This section is about theming the content of you windows. Especially the background and font colors, but also the form of menus and buttons.
==Kvantum== <!--T:15-->


<!--T:16-->
Using Kvantum is a good way to get a matching qt5 and openbox theme with a modern look


Instructions to have a unified theme for all your GTK2/3/Openbox and Qt4/5 applications and be able to customize them:


===1.===
<!--T:17-->
Choose <code>GTK+</code> in <code>lxqt-config</code> (LXQt Configuration Center --> LXQt Appearance)
To install Kvantum and set a theme that matches your preferences follow the instructions [[Kvantum|here]].


===2.===
Install the LXDE theme switcher:
sudo pacman -S lxappearance
Open it by clicking on: Start Menu --> Settings --> Appearance.


Unfortunately, this functionality is not implemented in LXQt yet. Therefore, the LXDE theme switcher is still needed.
<!--T:18-->
After saving the settings in Kvantum Manager, open the "LXQt Configuration Center" and select "Appearance". Set the "Qt Style" on the "Widgets Style" tab to Kvantum.


===3.===
Install well maintained themes supporting [http://gnome-look.org/index.php?xcontentmode=167 GTK2/3] and [http://box-look.org/index.php?xcontentmode=7402 Openbox]


<!--T:19-->
{{tip|Using a Kvantum theme that has a matching GTK theme will give everything a uniform look}}


Examples:


sudo pacman -S menda-themes-dark
==Window Theming== <!--T:20-->


sudo pacman -S menda-themes
<!--T:21-->
 
The window title bars are drawn onto your screen by the window manager you use. The default window manager of LXQt is Openbox.
yaourt -S vertex-themes
 
Edit manually the theme files to further customise if you like.
 
===4.===
 
For customising a pure Qt4/5 system you can use the preinstalled qtconfig-qt4 and its qt5 version, [http://qt-apps.org/content/show.php/Qt5+Configuration+Tool?content=168066 qt5ct] which you can easily compile, (as of this writing) if you have qt5 version 5.4.0 or higher.
 
 
After installation you need to put this in your <code>~/.bashrc</code> file:
 
export QT_QPA_PLATFORMTHEME=qt5ct
 
And after a qt5 upgrade you may need to re-install/compile <code>qt5ct</code>.
 
 
Your customisation by this tool will not be honoured immediately (only) by <code>pcmanfm-qt</code> which runs in your LXQt system in daemon mode. In order for it to honour your customisation you need to re-login.




In addition to the preinstalled qt theme engines you can install <code>qtcurve-qt4</code> and <code>qtcurve-qt5</code> from the repo by:
<!--T:22-->
To configure OpenBox, open the "LXQt Configuration Center" and select "Openbox Settings".  Then select the same theme you choose in Kvantum.


sudo pacman -S qtcurve-qt4 qtcurve-qt5


==GTK Theming== <!--T:23-->


And you can install <code>virtuality</code> AUR packages by:
<!--T:24-->
LXQt now provides an easy way to set the themes for GTK2 and GTK3 applications.


yaourt -S virtuality-qt4-git virtuality-qt5-git


<!--T:25-->
Open the "LXQt Configuration Center" and select "Appearance".  On the "Widget Style" there are dropdowns to select the GTK styles.


Those two theming engines by themselves have some customisability too. With <code>qtcurve</code> you need to manually edit the <code>~/.config/qtcurve/stylerc</code> file.




Another theme engine is <code>kvantum</code>:
==Panel Theming== <!--T:26-->
 
yaourt -S kdestyle-kvantum-kde4-git
 
 
It doesn't have KDE dependencies, but its said customisation utility seemingly only works in KDE (at this time) as I couldn't see any such utility in my system after installing it. <code>kvantum</code> can be installed as a qt5 app as well, but since there's no separate qt5 AUR package, you need to install it once more as a qt5 app. To do that you should edit the package content when <code>yaourt</code> ask you to; just replace the "qt4" entries with "qt5".

Additionally there are more themes available for download in the [https://forum.manjaro.org/index.php?board=20.0 Manjaro LXQt subforum].
All Theme folders need to be unpacked into the following directory:
/usr/share/lxqt/themes/
Attention: Some themes do not fully work. Please read the comments about the recommended usage.
===Example:===
Please look at this [https://forum.manjaro.org/index.php?topic=18058.msg165462#msg165462 Chrome theme].
The downloaded folder needs to be unpacked and moved into the right location mentioned above. The final path to the "chrome" folder has to be

All of these example do '''not''' provide '''complete''' icon themes. Especially in the LXQt Configuration Center are icons missing. Some application icons can be missing, too. You can easily identify applications and settings with missing icons by opening the start menu and looking at all the icons in it.
 
Please read the next chapter (chapter 5) for a tutorial on how to assign new/other icons.

=Change Order of Icons on Panel=
 
You can click the right mouse button on top of a panel element in order to move it. Alternatively, you can move panel elements by holding <code>CTRL+Left Mouse</code> and draging the element. These methods work for all panel elements, except Quick Launch / Starter elements.
 




If you want to move Quick Launch / Starter elements on your panel, you need to manually edit a file. Open the following file in a text editor:
==Create Custom Icon in Start Menu / Mainmenu== <!--T:52-->
~/.config/lxqt/panel.conf
Note that all folder names beginning with a dot are hidden folders. You need to make them visible by clicking View --> Show Hidden in your PcManFM-Qt File Browser. The <code>~</code> directory is your home folder.


<!--T:53-->
Read the [https://wiki.manjaro.org/index.php?title=LXQt_Theming#Create_Custom_Icon_on_Panel previous chapter] of this Wiki tutorial in order to get familiar with the content of <code>.desktop</code> files.


Please note the order of whole paragraphs beginning with <code>[square brackets]</code>. Changing the order of whole paragraphs beginning with <code>[square brackets]</code> does '''not''' move items on your panel. All paragraphs are sorted alphabetically. Pay attention to the paragraphs with the title <code>[quicklaunch]</code>. This is the panel element, which contains multiple Quick Launch / Starter items.
<!--T:54-->
Now, a custom <code>.desktop</code> files needs to get created (as root) in this location:


The order of every Quick Launch / Starter item can be adjusted separately within the <code>[quicklaunch]</code>. Simply changing the order of whole paragraphs beginning with <code>[quicklaunch]</code> does '''not''' move Quick Launch / Starter items on your panel, you also need to rename them.
<!--T:55-->
/usr/share/applications/


===Example:===
<!--T:56-->
You have the following Quick Launch / Starter items:
Please look at other <code>.desktop</code> files as examples for the <code>.desktop</code> file content: All have a category specified, e.g.


  [quicklaunch2]
  <!--T:57-->
alignment=Left
Categories=Qt;KDE;Settings;
apps\1\desktop=/usr/share/applications/pcmanfm-qt.desktop
apps\size=1
type=quicklaunch
[quicklaunch3]
alignment=Left
apps\1\desktop=/usr/share/applications/qterminal.desktop
apps\size=1
type=quicklaunch
[quicklaunch4]
alignment=Left
apps\1\desktop=/usr/share/applications/firefox.desktop
apps\size=1
type=quicklaunch


and you want to have the Mozilla Firefox icon on the left (of all these 3 icons). Please edit the file to look like this:
<!--T:58-->
This setting is important for the Start Menu / Mainmenu category this custom icons appears in. Use it.


[quicklaunch2]
<!--T:59-->
alignment=Left
Another important line in the <code>.desktop</code> file is:
apps\1\desktop=/usr/share/applications/firefox.desktop
apps\size=1
type=quicklaunch
[quicklaunch3]
alignment=Left
apps\1\desktop=/usr/share/applications/pcmanfm-qt.desktop
apps\size=1
type=quicklaunch
[quicklaunch4]
alignment=Left
apps\1\desktop=/usr/share/applications/qterminal.desktop
apps\size=1
type=quicklaunch


Please restart your panel (see below) to see the changes. This method usually works, but not very precisely. Sometimes the order of Quick Launch / Starter icons is different than specified in the file. Deleting a Quick Launch / Starter item can help, but not always.
<!--T:60-->
OnlyShowIn=LXQt;


<!--T:61-->
If this is set to another desktop environment, set it to LXQt or delete this line entirely in order to see this custom icon in your Start Menu / Mainmenu.




If you want to move Quick Launch / Starter item to the far left or right of the panel, please edit the paragraph belonging to the Quick Launch / Starter item and use one of the following lines:
==Change Order of Icons on Panel== <!--T:62-->


alignment=Left
<!--T:63-->
alignment=Right
You can click the right mouse button on top of a panel element in order to move it. Alternatively, you can move panel elements by holding <code>CTRL+Left Mouse</code> and draging the element. These methods work for all panel elements, except Quick Launch / Starter elements with added icons.


This Method works for all panel elements, but please keep in mind that all other panel elements, except Quick Launch / Starter elements can be moved by clicking the right mouse button on top of a panel element in order to move it.
<!--T:64-->
 
Quick Launch / Starter elements have "Move Left" and "Move Right" as right click options, which do enable you to freely move it. Just click the "Remove from quicklaunch" in order to remove the icon from the Quick Launch Widget.
 
 
In order to see the changes logout and log in again. If you want to see the changes immediately run the following commands:
 
killall lxqt-panel
lxqt-panel


Sometimes, executing <code>lxqt-panel</code> is enough to reload the panel.
<!--T:65-->
Now, you can move the Quick Launch Widget like all other panel elements. After you have moved the Quick Launch Widget to the desired position on your panel, follow [https://wiki.manjaro.org/index.php?title=LXQt_Theming&action=edit#Create_Custom_Icon_on_Panel this tutorial] to add your icon again.

Overview

LXQt is a free and open source lightweight Qt desktop environment that was formed from the merger of the LXDE and Razor-qt projects. It is focused on being a classic desktop with a modern look and feel. The official website for LXQt can be accessed here.


Lxqt-de-18.png


Installation

Instructions for installing LXQt can be found on the Install Desktop Environments page.


Window Managers

LXQt is designed to be used with any window manager and does not provide one by its own.


KWin

See article LXQt_with_kwin


Configuration

LXQt provides the lxqt-config (LXQt Settings) application for configuration.

Global Keyboard Shortcuts

Global shortcuts can be configured by the lxqt-config-globalkeyshortcuts application (LXQt settings -> Global Shortcuts): 

   <Screenshot TBD>
warning
Mapping the Super_L/Super_R keys (<Meta> without a second key) can lead to unexpected behaviour and is not recommended!


note
Some window manager (kwin, openbox, etc.) specific shortcuts are not configurable by LXQt (e.g. "Alt+Tab" for the task switcher). Those are configured by the window manager.


Theming

In can take a few steps to get everything matching on LXQt since it is a collection of things. There are a few different things that are separately themed:

  • GTK2/GTK3
  • QT
  • Openbox
  • LXQt panels


Kvantum

Using Kvantum is a good way to get a matching qt5 and openbox theme with a modern look


To install Kvantum and set a theme that matches your preferences follow the instructions here.


After saving the settings in Kvantum Manager, open the "LXQt Configuration Center" and select "Appearance". Set the "Qt Style" on the "Widgets Style" tab to Kvantum.



Tip
Using a Kvantum theme that has a matching GTK theme will give everything a uniform look


Window Theming

The window title bars are drawn onto your screen by the window manager you use. The default window manager of LXQt is Openbox.


To configure OpenBox, open the "LXQt Configuration Center" and select "Openbox Settings". Then select the same theme you choose in Kvantum.


GTK Theming

LXQt now provides an easy way to set the themes for GTK2 and GTK3 applications.


Open the "LXQt Configuration Center" and select "Appearance". On the "Widget Style" there are dropdowns to select the GTK styles.


Panel Theming

Panel theming is available via the LXQt Configuration Center --> LXQt Appearance --> LXQt Theme


Change Mouse Cursor

Mouse cursor theming is available via the LXQt Configuration Center --> LXQt Appearance --> Cursor.

Adwaita is the default mouse cursor theme in LXQt. Other mouse cursor themes can be downloaded. Example of a mouse cursor theme: 

sudo pacman -S xcursor-menda


Change Icon Theme

The icon theme can be changed via LXQt Configuration Center --> LXQt Appearance --> Icon Theme

The default icon theme of LXQt is oxygen-icons. It is a relatively large download, but pretty complete.


Change Icons of Applications and System Settings

The path of icons is saved in .desktop files. For each application you can find their corresponding .desktop files in one of these two locations: 

/usr/share/applications/

~/.local/share/applications/

Note that all folder names beginning with a dot are hidden folders. You need to make them visible by clicking View --> Show Hidden in your PcManFM-Qt File Browser. The ~ directory is your home folder.


Open a .desktop file with a text editor with root privileges and look for the following line: 

Icon=

Insert the path to the icon you want to use after the = symbol. A lot of system icons can be found in this location: 

/usr/share/icons/


Example:

If you want to use a flag icon, use this line in the .desktop file: 

Icon=/usr/share/icons/gnome/48x48/apps/locale.png


Create Custom Icon on Panel

Right click on your panel and choose "Add panel widget". Then add a Quick Launch / Starter widget. A text will appear on your panel.

You can drag and drop any icon (from your start menu / mainmenu or your custom icon file) there in order to create a Quick Launch / Starter icon in your panel. You can even drop multiple icons / icon files on one Quick Launch / Starter widget.

But if you want your custom icon in your panel, you must first create your own .desktop file (please keep reading).

Example:

For demonstration purposes, let's create a custom icon, which will shut down our computer when clicked:

First, let's create a new file (e.g. in your home directory or any other directory you want): Right click and choose "Create New" --> "Blank File". Name the file ShutDown.desktop. You can choose any name you want, but the .desktop in the end is important.

Next, edit this file with a text editor. It's file content is supposed to look like: 

[Desktop Entry]
Type=Application
Name=ShutDown
Comment=Shut down my computer
Exec=poweroff
Icon=/usr/share/icons/Menda-Circle/actions/scalable/bottom.svg
  • Name= is the name of the icon
  • Comment= gets shown when you hover with your mouse cursor over the icon
  • Exec= defines the terminal command, which is executed when the icon is clicked
  • Icon= specifies the path to the icon


Finally, you can drag and drop your custom icon file onto a Quick Launch / Starter widget in your panel (as described in the beginning of this chapter) to create your custom panel icon.


Create Custom Icon in Start Menu / Mainmenu

Read the previous chapter of this Wiki tutorial in order to get familiar with the content of .desktop files.

Now, a custom .desktop files needs to get created (as root) in this location: 

/usr/share/applications/

Please look at other .desktop files as examples for the .desktop file content: All have a category specified, e.g. 

Categories=Qt;KDE;Settings;

This setting is important for the Start Menu / Mainmenu category this custom icons appears in. Use it.

Another important line in the .desktop file is: 

OnlyShowIn=LXQt;

If this is set to another desktop environment, set it to LXQt or delete this line entirely in order to see this custom icon in your Start Menu / Mainmenu.


Change Order of Icons on Panel

You can click the right mouse button on top of a panel element in order to move it. Alternatively, you can move panel elements by holding CTRL+Left Mouse and draging the element. These methods work for all panel elements, except Quick Launch / Starter elements with added icons.

Quick Launch / Starter elements have "Move Left" and "Move Right" as right click options, which do enable you to freely move it. Just click the "Remove from quicklaunch" in order to remove the icon from the Quick Launch Widget.

Now, you can move the Quick Launch Widget like all other panel elements. After you have moved the Quick Launch Widget to the desired position on your panel, follow this tutorial to add your icon again.


Change Icon of Start Menu / Mainmenu

This Icon can be changed by opening the following folder with root privileges: 

/usr/share/lxqt/themes/<theme name>/

Replace <theme name> with the name of the theme you are currently using. The name of your current theme can be found in System Settings>LXQT Configuration Center>LXQtAppearance>LXQt Theme. The Start Menu icon will only get changed for <theme name>. All other themes still use the default icon!

In this folder, you find a mainmenu.png file. It is the icon of your Start Menu (called "Mainmenu" in LXQt). Replace this file with the icon file you want to use. Rename your icon file to the same name.


Great icons can be found in this thread: https://forum.manjaro.org/index.php?topic=15613.0


In order to see the changes logout and log in again. If you want to see the changes immediately run the following commands: 

killall lxqt-panel
lxqt-panel
