Can I make Eclipse on Ubuntu look more compact? [duplicate]

Gigantic Tabs in Eclipse on Ubuntu

Back when I was using Eclipse on Ubuntu 10.04 LTS, I found that the tabs and bars used a bit too much vertical spacing, which made the interface a bit too spacey for my taste.

However, I didn't find a good way to make this right, and I learned to work with it.

But now, after installing Ubuntu 12.10 (or actually Linux Mint 14 Cinnamon), it has gotten even bigger, the vertical spacing.

If you have three tabbed windows with two toolbars in your normal vertical workspace, this easily hides 6 lines of code with useless UI spacing, which I personally find quite annoying.

Before screenshot (a bit too spacey) | After screenshot (annoyingly spacey):

I personally don't like this and I would prefer to get rid of it. I have tried some GTK3 themes and they left stuff almost equally spacey, adding or removing maybe an extra pixel.

I have traveled deep into the preferences of Eclipse itself and I have seen many things. I am not sure if I was distracted or there is just no way of changing this from within Eclipse itself, but I didn't find any.

How do I turn this oversized touch interface for people with 4K screens back into a compact interface for programmers who want to see lots of code?

or

How do I brutally do this myself in /usr/share/themes/*/gtk-3.0/*css?

I have been looking everywhere for a GTK3 solution, because I was sure the switch to a GTK3 system caused this. However, after two hours of wasting my time, I found out that the 'old GTK2 trick' just works.

Add a new file called .gtkrc-2.0 to your home directory with the following content:

style "gtkcompact" {   GtkButton::default_border={0,0,0,0}   GtkButton::default_outside_border={0,0,0,0}   GtkButtonBox::child_min_width=0   GtkButtonBox::child_min_heigth=0   GtkButtonBox::child_internal_pad_x=0   GtkButtonBox::child_internal_pad_y=0   GtkMenu::vertical-padding=1   GtkMenuBar::internal_padding=0   GtkMenuItem::horizontal_padding=4   GtkToolbar::internal-padding=0   GtkToolbar::space-size=0   GtkOptionMenu::indicator_size=0   GtkOptionMenu::indicator_spacing=0   GtkPaned::handle_size=4   GtkRange::trough_border=0   GtkRange::stepper_spacing=0   GtkScale::value_spacing=0   GtkScrolledWindow::scrollbar_spacing=0   GtkTreeView::vertical-separator=0   GtkTreeView::horizontal-separator=0   GtkTreeView::fixed-height-mode=TRUE   GtkWidget::focus_padding=0 } class "GtkWidget" style "gtkcompact" 

Restart Eclipse.

Wasted space back to efficient use!

Now that I myself have (finally) moved to Kepler, I found that the little minimize-maximize widgets wouldn't go below 28 pixels anymore. These .gtkrc-2.0 seem to have better results for Kepler.

style "gtkcompact" {    GtkButton::defaultborder={0,0,0,0}    GtkButton::defaultoutsideborder={0,0,0,0}    GtkButtonBox::childminwidth=0    GtkButtonBox::childminheigth=0    GtkButtonBox::childinternalpadx=0    GtkButtonBox::childinternalpady=0    GtkMenu::vertical-padding=1    GtkMenuBar::internalpadding=0    GtkMenuItem::horizontalpadding=4   GtkToolbar::internal-padding=0    GtkToolbar::space-size=0    GtkOptionMenu::indicatorsize=0    GtkOptionMenu::indicatorspacing=2    GtkPaned::handlesize=4    GtkRange::troughborder=0    GtkRange::stepperspacing=0    GtkScale::valuespacing=0    GtkScrolledWindow::scrollbarspacing=0    GtkExpander::expandersize=10    GtkExpander::expanderspacing=0    GtkTreeView::vertical-separator=0    GtkTreeView::horizontal-separator=0    GtkTreeView::expander-size=8    GtkTreeView::fixed-height-mode=TRUE    GtkWidget::focuspadding=1  }  class "GtkWidget" style "gtkcompact"  style "gtkcompactextra" {    xthickness=2 ythickness=2  }  class "GtkButton" style "gtkcompactextra" class "GtkToolbar" style "gtkcompactextra" class "GtkPaned" style "gtkcompactextra" 

If you add the xthickness and ythickness to the whole GtkWidget class, your menu bar will be all tight and squeezed together. That's too much in my opinion, but just so you know.

You can edit the file and save it, open up something simple like Geany, tweak save, re-open Geany etc. to quickly tweak this. For details you can open Eclipse every time, but it takes longer to load, depending on how much plugins you have to load.

About Luna and Mars

@eocanha said at jan 15:

If you have Gtk3 installed, Eclipse Luna will use the Gtk3 CSS based styling system and will ignore .gtkrc-2.0. However, you can force Eclipse to use Gtk2 again (if you have it installed) via shell environment variables: "export SWT_GTK3=0" in your .bashrc or in some wrapper script calling Eclipse.
