Installing the "Sweet GTK theme" possible in Lubuntu 20.04?

[Rosika2]

Hi all,

I´ve got a question regarding the possible installation of the “Sweet GTK theme” in Lubuntu 20.04.

On https://www.addictivetips.com/ubuntu-linux-tips/install-sweet-gtk-theme/ there´s some detailed info regarding the installation of that theme.
I have to admit the theme seems very interesting and I´d like to try it out.

It should be possible by doing the following:

git clone https://github.com/EliverLara/Sweet.git
cd Sweet
mkdir -p ~/.themes
cd ~/
mv Sweet ~/.themes

Then - to get the matching icon theme:

download from https://www.gnome-look.org/p/1253385#files-panel the Aqua Dark TarXZ archive (although I couldn´t find it there) and then:

tar -xvf Aqua-Dark.tar.xz
mkdir -p ~/.icons
mv Aqua-Dark ~/.icons/

After that: enabling Sweet (“settings” …)

All this seems pretty straight-forward but at the end of the page they say:

Note: Sweet is a GTK-based theme, so it will not work on desktop environments like KDE Plasma 5, LXQt, or other non-GTK environments.

Hmm, that got me wondering:

Despite the fact that Lubunutu 20.04 makes use of the LXQt DE I still seem to be able to utilize GTK themes…?

See screenshot.

What do you think?

Many thanks in advance and many greetings.

The GTK2/3 components only impact the programs that are GTK2/GTK3 with regards theming; ie. the GTK2 & GTK3 themes have no impact on any Qt5 application or the desktop itself.

I use hexchat still as my IRC client, it’s a really old GTK2 program that eventually I’ll get around to switching away from… it’s on my todo list but I never get there… but it’s useful right now so when I make a change to the GTK2 theme setting in my LXQt Appearance Configuration setting you highlight; I see the effect in that program, but nowhere else on my desktop.

My desktop isn’t impacted (it’s LXQt & thus Qt5 themed), no other windows I have open use GTK2 theming.

Yes the theme can have effect on your system, but not in the way you are hoping for I suspect, thus the warning on the site it came from - as your system won’t use it except for pointing applications that are looking for what GTK theme to use to it (eg. hexchat is GTK2 & gets told to use the GTK2 theme I selected; no other window is impacted)

In my opinion; you want GTK2/3 themes that match the LXQt theme you’re using; otherwise the effect is blinding or distracting in my opinion; but I don’t have great aesthetics I’ll admit, so what works for you, you’ll have to decide. LXQt themes impact your real desktop.

Hi Chris,

thank you so much for the clarification.

I have to admit I didn´t know that. So everything´s clear now.

So I guess for having to install a new set of themes regarding the LXQt DE I´d have to look for dedictaed LXQt themes.

I looked around a bit and found some on pling (https://www.pling.com/ )
There I used “LXQt” as search filter and got the following site as a result:
Search: theme .

There are 7 sub-pages but sadly the “sweet theme” isn´t included.

Well, for what ist´s worth I still learned something new.

Many thanks again for your kind help, Chris.

Have a nice weekend and many greetings.
