Make Eclipse look better on Ubuntu

• Compact the look and fix unreadable selected entry in content assist in some themes (e.g. Ambience) by creating a new text file called "gtkrc" (a stylesheet file for GTK apps) with the following content:- 

gtk-color-scheme = "selected_text_color:#000000"
style "compact"
{
  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=1
  GtkMenuItem::horizontal_padding=4
  GtkToolbar::internal-padding=1
  GtkToolbar::space-size=1
  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
  GtkExpander::expander_size=10
  GtkExpander::expander_spacing=0
  GtkTreeView::vertical-separator=0
  GtkTreeView::horizontal-separator=0
  GtkTreeView::expander-size=12
  GtkTreeView::fixed-height-mode=TRUE
  GtkWidget::focus_padding=0

  font_name="Liberation Sans,Sans Regular 8"
  text[SELECTED] = @selected_text_color
}
class "GtkWidget" style "compact"
style "compact2"
{
  xthickness=1
  ythickness=1
}
class "GtkButton" style "compact2"
class "GtkToolbar" style "compact2"
class "GtkPaned" style "compact2" 

• To use the above stylesheet with Eclipse (my version is Indigo - 3.7.1), run Eclipse like this:-

GTK2_RC_FILES=$GTK2_RC_FILES:/somewhere_1/gtkrc /somewhere_2/eclipse

• Make tooltip readable by using #000000 as its foreground colour (tooltip_fg_color) and #f5f5b5 as background (tooltip_bg_color) in the following files:- 

/usr/share/themes/<your-current-theme>/gtk-3.0/settings.ini
/usr/share/themes/<your-current-theme>/gtk-3.0/gtk.css
/usr/share/themes/<your-current-theme>/gtk-2.0/gtkrc

• Install Eclipse theme colour plugin and may want to try my TumCode theme which keeps the number of colours to the minimum.
   
• Replace the default "Monospace" font with "Liberation Mono" and optionally reduce the font size to 8 or 9.

Windows -> Preferences -> General -> Appearance -> Colors and Fonts

(for Java Editor Text Font, Javadoc display font, Properties File Editor Text Font, etc.)

Here is how it looks after the above changes:-
