Tabs are huge in Eclipse on Ubuntu

You might have noticed the tabs are a bit bigger in Eclipse than what you’re used to when running Eclipse in Windows.
(This is a minor annoyance, but more screen real estate is always welcome..!)
This is what it would look like before:

You can solve this by creating a custom gtkrc-2.0 file, which should be in your home folder.
Start up your terminal and execute the bold text:

joris@dipshit:~$ nano ~/.gtkrc-2.0

You’re in nano right now, insert the following text in .gtkrc-2.0:

style "compact-toolbar"
{
        GtkToolbar::internal-padding = 0
        xthickness = 1
        ythickness = 1
}
style "compact-button"
{
        xthickness = 0
        ythickness = 0
}
class "GtkToolbar"                              style "compact-toolbar"
widget_class "*<GtkToolbar>*<GtkButton>"        style "compact-button"

Press “CTRL+x” to close the file and press “Y” to save the edited contents.
Next time you’ll open eclipse, the tabs will look like this:
