[[!meta title="QT4 user interface prototype added to ceofhack"]] In the last weeks there has been a lot of stuff done in the **user_interface** branch of [[ceofhack|software/ceofhack]]. The communication between a user interface (UI) and ceofhack is described (read as in: finished!). Thus, if you are a (G)UI programmer and like the idea of ceofhack, you can now begin to implement your user interface. This is what someone already did and thus there is now a prototype of a QT4 gui in the **user_interface** branch available! This new UI does indeed look much better than the included command line user interface (**ui-cmd**), but it's your decision what to use with [[ceofhack|software/ceofhack]].
