Hi kde's users.I 'm a new user of kde I discover few years ago but I give it up because theming it very difficult is.
But I wanted to change of GTK and discover Qt and Freecad and I'm already on Fédora so I installed CentOs 7.2 with KDE4.14.8
After many problems to establish a connection (manually and remove NetworkManager) I attempt to changing window decoration.
I prefer making it manually because my little experience showed me automatic's config program doesn't work always.
And it's still the case.

I read Kde Techbase,Userbase,wiki etc and many informations around forum's and web but I don't achieve in installing one and I don't understand why.So I desperate a so easy thing to do by other workspace is so difficult in Kde.And I think you will be surprise too as far me.

First I got new stuff in downloading some of theme with window settings (2 only because connection doesn't work but icon,mouse etc works )
I repeat it but no connection is establish with kde-look for window decoration.I downloaded it but no button to install a theme from locally.
I seek for the web where theme are stored.I find /usr/share/kde4/apps/kwin/ and especially aurorae for Aurorae theme.

Code: Select all

[biscotte@cracotte ~]$ cd /usr/share/kde4/apps/kwin/
[biscotte@cracotte kwin]$ ls -al

Where are stored the .png of the theme because I can't extract my theme here?
For example Keramik I read keramik.desktop of the theme there is only name and X-KDE-Library=kwin3_keramik.
I install kthememanager but no change.And I found no solution on the web.And I install Smaragd with instructions on install files after extract it but it don't appear in windows list so it means it isn't installed correctly altough compilation process is good

Someone can help me to understand kwin theming configuration files because I understand nothing.
Does I create a mytheme.desktop in /usr/share/kde4/apps/kwin/ after extract it in my user's theme folder.And point it to my image or something else.
I'm dissapointed.I though it was easier than other workspace.But i continue to seek for a solution to theming my workspace.
Sorry for my english.I don't practice a lot of.
