UxThemeGTK is a wrapper around the GTK+ rendering engine implementing the standart Windows Visual Styles API. This can help you to make your Wine applications looking really native in GNU/Linux (see the screenshots below).

(Tested in Ubuntu 14.10)

1. Make sure you have the following packages installed:

   $ sudo apt-get install git libgtk-3-dev wine1.6-dev

2. Get the sources:

   $ git clone https://github.com/akulinchev/uxthemegtk.git

3. Now you need to compile it.

   $ cd uxhtemegtk
   $ make

4. Find uxtheme.dll.so. There may be more than one!

   $ find /usr/lib -name "uxtheme.dll.so"
   /usr/lib/i386-linux-gnu/wine/uxtheme.dll.so
   /usr/lib/x86_64-linux-gnu/wine/uxtheme.dll.so

5. Don't forget to make a backup!

   $ sudo cp /usr/lib/x86_64-linux-gnu/wine/uxtheme.dll.so /usr/lib/x86_64-linux-gnu/wine/uxtheme.dll.so.old

6. Copy the binary you have compiled at the step 3 in the directory you have found at the step 5.

   $ sudo cp uxtheme.dll.so /usr/lib/x86_64-linux-gnu/wine/uxtheme.dll.so

7. Enjoy it!

   $ wine64 winecfg

UxThemeGTK is an experimental software. If you found a bug, let me know.
