Hello everyone,

I've been doing a lot of searching for the answer to this and surprisingly, I can't seem to find it anywhere.

Simply, how do I make the background of the window transparent?

It's easy enough to choose a window decoration with a transparent title bar and borders, but the actual window content background is always an opaque block. I'm trying for an effect like below.

Cheers.

stock oxygen cannot do this.
oxygen-transparent, qtcurve and bespin are the only gui styles capable of this.

Sorry ... I'm not quite sure what you're talking about.

Where and how can I change this?

Thankyou.

You can't.

You need to install one of the styles I mentioned - your distro is likely gonna provide qtcurve, no idea about the other two. They're binary libraries, you cannot "just" install them via kde-look or so.

"kcmshell4 style" opens the KDE style config dialog, there you need to select the style of your choice and for QtCurve and Bespin will also have to configure them to make use of translucent windows.

Thankyou very much for your help.

It's surprisingly difficult to find that information on the web! I Googled for about two hours and only found people asking the same question and getting the wrong response.

For any of those that find this post through a web search, the answer is, as luebking says, this isn't a theme you can download anywhere or adjust with the default settings out of the box. It's fairly easy to install though. Do a Google search for "installing oxygen-transparent" and you should find instructions for downloading and compiling. It's not hard.

Then when you go into System Settings -> Application Appearance, under the "Applications" tab there's a drop down box labelled "Widget Style". For the default styles, the configure-button to the right of that is disabled. But once you install one of these styles that supports transparency (oxygen-transparent, qtcurve, etc.) you can adjust the settings via the configure button.
