Linux Huge Toolbar Problem
Eclipse 4 on Linux GTK looks terrible. Main reason is to Huge widget size. You can fix it by defining gtk 2.0 layout. And What if you are using Linux Mint, You will see horrible background of Toolbars.
After installation of Jeeeyul's Eclipse Themes, You can find Launch GTK 2.0 RC Wizard from toolbar menu.
This menu will shows a wizard that will download GTK 2.0 Runtime Configuration and ask restart eclipse.
What if you want to revert GTK configuration, Just remove ~/gtkrc-2.0 file.
$ rm ~/.gtkrc-2.0I am not good at linux and GTK. If you have better example or explanation. Please update this document. What if you defined better .gtkrc-2.0 then please make a pull request.
