What is it?

• The GANGA GUI is a dynamically generated Graphical User Interface with:– useful information displays (e.g. monitoring)– ease of use (e.g. job building)– additional tools (e.g. scriptor)

• It is designed to be an alternative user interface to the GANGA Command Line Interface (CLI).


What’s in it?

• PyQt (Python bindings to C++ Qt graphics toolkit)

• Pure Python

• Based on the GANGA Public Interface (GPI).The GANGA Command Line Interface is also based on the GPI.


Who is it for?

• The user who is more comfortable in the GUI environment but does not want to compromise on the flexibility and power provided by the GANGA CLI.

• The GANGA plug-in developer gets for free the graphical display, interaction and manipulation of his/her plug-in WITHOUT a single line of GUI code.


How does it look?

• The GANGA GUI consists of a set of dockable windows and a central job monitoring panel.
