With highlighting for Gedit, I was happy to give you the convenience of a nice editor to work on OpenCL-files. But it seems that one of the most popular IDEs for C++-programming is Qt Creator. So you receive another free syntax highlighter. You need at least Qt Creator 2.1.0.
The people of Qt have written everything you need to know about their Syntax highlighting, which was enough help to create this file. You see that they use the system of Kate, so logically this file works with this editor too.
In this article there is all you need to know to use Qt Creator with OpenCL.
Installing
First download the file to your computer.
Under Windows and OSX you need to copy this file to the directory shareqtcreatorgeneric-highlighter in the Qt installation dir (i.e. c:Qtqtcreator-2.2.1shareqtcreatorgeneric-highlighter). Under Linux copy this file to ~/.kde/share/apps/katepart/syntax or to /usr/share/kde4/apps/katepart/syntax (all users). That’s all, have fun!
