Last week, we released the Enthought Tool Suite 3.6. John Wiggins made many improvements and bug fixes to Kiva, Enable, and Chaco. And thanks to Evan Patterson, the TraitsBackendQt now supports PySide (as well as PyQt4).
We are also happy to announce that immediately after the release, the ETS repository was moved from subversion to git, and is now hosted on github.
This new ETS will be included in EPD 7.0, which is Python 2.7-based and is scheduled to be released on February 8.
Occasionally I want a slider to control 2 values, such as defining a date range or clipping parameters. In the past, I would just create 2 sliders using the RangeEditor. It worked fine, but took up 20 or so pixels and didn’t really visually show the relationship between the 2 variables.

Qt and PyQt made it ridiculously easy to create the control I wanted. I started off transcoding the Qt QSlider C++ code into python, then added the second slider. In all, its about 180 lines of Python, less than 50 of it specific to the seconds slider.
I also wrapped this into a Traits editor, which can be found at enthought.traits.ui.qt.extra.bounds_editor.BoundsEditor
