gtkTtk is a ttk theme that gives to your Tk applications a native GTK look and feel. So applications made using TCL/Tk, Perl/TK or Python/Tkinter can now look as good as if they were written in C/GTK and integrate perfectly in Gnome or XFCE desktops.

gitk, git gui and other popular TK applications will no more looks like comming from the 90's !

gtkTtk is a fork of tile-gtk. Since according to the author tilegtk as well as tileqt is undermaintained, I created this fork to integrate my improvements and bugfixes and finishing the work to have a complete GTK look on ttk applications.

cmake -DCMAKE_INSTALL_PREFIX=`tclsh <<< 'puts [lindex $auto_path end]'`
make
make install

(sudo make install if you're not root)

The easiest way is to install ttk-theme-chooser And select gtkTtk as your ttk theme :
