Enthought Tool Suite (ETS) v3.3.0 released

I’m pleased to announce that Enthought Tool Suite (ETS) version 3.3.0 has been tagged and released! Please see below for a partial list of changes for this release.

PyPi has been updated with the release, including the availability of both Windows binaries (.egg) and source distributions (.tar.gz). A full install of ETS can be done using a command like: easy_install -U “ETS[nonets] == 3.3.0”

HOWEVER, it is important to note that there are still package dependencies that are outside the scope of easy_install. Therefore, we recommend that you have the following installed prior to installing ETS:

  • setuptools: minimum version 0.6c9
  • VTK: minimum version 5.0, recommended 5.2 or later

And at least one of:

  • wxPython: minimum version
  • PyQt: minimum version 4.4

For additional installation information, see: https://svn.enthought.com/enthought/wiki/Install

What Is ETS?

The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and the open-source community, which we use every day to construct scientific applications. It includes a wide variety of components, including:

  • an extensible application framework
  • application building blocks
  • 2-D and 3-D graphics libraries
  • scientific and math libraries
  • developer tools

The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes.

More information on ETS is available from the development home page: http://code.enthought.com/projects/index.php

ETS 3.3.0 is a feature-added update to ETS 3.2.0, including numerous bug-fixes. Some of the notable changes include (sub-projects listed in alphabetical order):

Chaco 3.2.0 (July 15, 2009)


* Bounded grids – Horizontal and Vertical grid line start and end points can now be set to a fixed value in data space, or to be the return value of an arbitrary callable. The start and end tick can also be configured via the data_min and data_max traits.

* Added dictionary interface to ArrayPlotData

* Added a Traits UI view to the ScalesAxis

* Added a new chaco.overlays subpackage and a new overlay, the DataBox.

* Improved appearance of PlotToolbar

* Changed add_default_axis() in the plot_factory module to take an axis class as a keyword argument.

* Refactored contour plots into a common base class and implemented proper event handling when their colormaps or data ranges change.

* Changed default colormap on img_plot() and contour_plot() method of Plot to be Spectral instead of Jet.

* Added two more color palettes to the auto color palette, and created a default_colors module.

* Added CandlePlot renderer

* Changed Plot Labels to able to display inside the plot area, instead of only on the outside

* Added optional title attribute to plot legends

* Updated all containers to respect and use the new fixed_preferred_size trait on enable.Component

* New Examples:
* Interval trait editor as a Chaco example (from Stefan van der Walt)
* embedding an interactive Chaco plot inside a VTK RenderWindow using the new Enable VTK backend
* lasso tool on an image plot
* bounded grid
* candle plot


* Fixed call signature of ShowAllTickGenerator.get_ticks()

* Plot.title_font is now a delegate to the underlying PlotLabel object (from Chris Colbert)

* Fixed mouse event handling bug in RangeSelection (from Stefan van der Walt)

* ImagePlots now redraw when their input data changes.

* Fixed cached image invalidation in colormapped image plots

* Optimized ScatterPlot.map_index() when index_only is True and the index data is sorted

* Changed ColormappedScatterPlot to no longer incorrectly apply the fill_alpha to the outline color

* Improved date ticking heuristics in chaco.scales subpackage, specifically eliminating the bug where all times between, midnight and 1am would be formatted at too course of a time resolution.

* Cleanup of various examples (titles, appearance)

* The spectrum.py (audio spectrograph) example now properly closes the audio stream.

Enable 3.2.0 (July 15th, 2009)

enthought.enable Enhancements

* Added Slider and Compass widgets

* Added an OverlayContainer (almost identical to the one in Chaco)

* Added ImageGraphicsContextEnable class so that one can always import a Kiva Image backend-based GraphicsContextEnable

* renaming marker_trait to MarkerTrait (the old name is still permitted for backwards compatibility, but should be avoided)

* Moved the scatter_markers module from Chaco to Enable, so that Enable components can use MarkerTrait

* Added an experimental VTK backend for Enable, along with an example

* Changed SVGButtonEditor toggle to draw a SVG under the button SVG instead of drawing a plain box

* Added labels for SVGButton

* Improving backbuffering performance on the Mac by creating the layer context from the window context instead of from a bitmap.

* Adding a “fixed_preferred_size” trait to Components, so that relative size preferences can be expressed amongst different components in a container

enthought.enable Fixes

* Improved the backend selection to match the Traits UI backend unless ETSConfig.enable_toolkit is explicitly set

* Fixed demo_main() in example_support.py so that it doesn’t crash IPython

* Windows with smaller parent are no longer opened at invalid positions with negative y values

* Implemented editable_labels attribute in the TabularEditor for enabling editing of the labels (i.e. the first column) * Fix bug in ListEditor where a trait change listener would be fired when intermediate traits changed (when extended_name was of the type item1.item2.item3..) leading to a traceback. * Saving/restoring windows now works with multiple displays of different sizes

* New ProgressDialog
