Every Linux GTK (and not only) them present horrible Eclipse IDE
I'm working with:
CentOs 7 GUI
Eclipse Mars 4.5
You can customize file in this path:
$YOURHOMEDIR/.p2/pool/plugins/org.eclipse.ui.themes_x.x.x.x.V.xxxxxx/e4_default_gtk.css
Modify css class as:
.MPartStack {
font-size: 9;
font-family: Liberation Sans;
swt-tab-renderer: null;
swt-tab-height: 22px;
swt-selected-tabs-background: #FFFFFF #ECE9D8 100%;
swt-simple: false;
swt-mru-visible: false;
}
to obtain decent tab style
Alternative to yuo can install Eclipse plugin :
Go to menu Help > Install new software, then install
E4 CSS editor (Incubation) plug-in using update site (add this link: http://download.eclipse.org/e4/updates/0.12). After restart, go to Window > Preferences, General > Appearance and now you can edit styles here for any selected theme
