Config to make Eclipse Juno icons and tabs look small and nice in Linux

.gtkrc-eclipse

# Create a new file in your home directory called .gtkrc-eclipse

# call eclipse with this command:
# Gtk2 forced:
# export SWT_GTK3=0
# env GTK2_RC_FILES=/usr/share/themes/<YourTheme>/gtk-2.0/gtkrc:/home/<YourUser>/.gtkrc-eclipse '/path_to_eclipse/eclipse'

# In your Eclipse directory find the file 'e4_default_gtk.css'
# In this file there's a CSS class:

# .MPartStack {
#     font-size: 11;
#     swt-simple: false;
#     swt-mru-visible: false;
# }

# And you have two possible solutions:

# 1. Change font-size to something smaller
# 2. Just comment out or remove font-size from this class (works well for me)

I can't express how thankful I am for this, THANKS MAN!

Great job!! Which parameter should be modified to get menu items ("File", "Edit", etc) a little bit more separated? All of them are too close to one another, it looks like a long phrase and not individual words...

Love your changes, tested on Kepler version and it looks so much better, had previous rc file just to change default fonts:

style "eclipse" {
font_name = "Sans Condensed 8"
}
class "GtkWidget" style "eclipse"

And with yours together is so pleasant to look at :) now if I work on 1920x1200 or 1280x720 it feels very usable and non-claustrophobic. Before I felt under pressure when moving with work from desktop to laptop.

Using this on Luna (4.4.1), works great, thanks so much. I wish this was the default.

@leslau Thanks, I'm back to Ubuntu today and looking how force GTK2 found your fork 👍

Thank you so much! Work on Eclipse Mars as well

Thanks a Lot !! :) Just tested it on Mars and Mint 17.3. Works perfectly

Hi, Is there a way to make small toolbar icon to standard size. I am running Eclipse on Windows 10 laptop having 3200 * 1800 resolution.

Thanks a Lot !!

Awesome ! Still an issue these days under Eclipse 4.5.2 / Archlinux + Cinnamon.

Thanks a lot! (my setup: Eclipse 4.5.2 / Archlinux + Cinnamon). Is this bug already reported?

Good work. Thanks a lot. Tested on Debian Jessie

Thanks!
You make my monkey developer day better.

Very nice! Worked on ubuntu 14.04

Truly appreciated..
I'm using the Eclipse Neon 4.6 (Ubuntu 16.04) and that script made my day 👍

Cool! Tried out on Eclipse Oxygen on Ubuntu Mate 16.10 beta2.
Thanks for the tip.

THX!!!
Linux Mint 18/Cinnamon with Eclipse neon.1

THX!!!

It works even on Oxygen GTK+ 2!
Just ignore the MPartStack bits (There aren't on .css file for Oxygen).
Thank you very much!!!

If you do wish to modify font-size under Eclipse Oxygen, this style has been refactored into e4_basestyle.css in this release.

Actually, for Oxygen we just need to force GTK 2 on Ubuntu 17.10.

Works for DBeaver (it is eclipse-based) on Debian Stretch
(css file can be found in /usr/share/dbeaver/plugins/org.eclipse.ui.themes_1.2.1.v20170809-1435/css/e4_default_gtk.css)
