From a46d4baad8a7cf0ecb2bb6e62bd7e33fbcdf8238 Mon Sep 17 00:00:00 2001 From: Laszlo Agocs Date: Tue, 17 Jan 2012 15:32:32 +0200 Subject: [PATCH] Implement selection offers from compositor to clients. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is a hack but works beautifully. It allows the compositor to participate in copy-paste which becomes mandatory when there is UI running in the compositor process.
