TraitsUI 7.1.0 is a minor feature release which introduces a new testing library and a number of significant fixes. Demo examples are also distributed as package data such that they are visible via the "etsdemo" GUI application (to be installed separately).

Highlights of this release

  • A new traitsui.testing.api module has been introduced for testing GUI applications built using TraitsUI. See Testing TraitsUI Applications for an introduction. Builtin support has been added for testing several TraitsUI editors. More support will be added in the future.
  • On OSX and Qt, there have been reports of missing UI view updates after a push button is clicked. While this is suspected to be a Qt issue, changes have been made to ButtonEditor, SetEditor and ImageEnumEditor to mitigate the situation.
  • The internal logic for disposing an instance traitsui.ui.UI is changed as an attempt to resolve AttributeError that occurs while a nested UI is removed.

Notes on upgrading

  • On the issue about Qt button not causing views to update on OSX, projects that have been working around the issue by adding GUI().process_events() (or similar) in their applications may now try to remove those workarounds. However, the change that mitigates the issue in a production environment has implications for tests: The button's click slot is no longer invoked immediately but always invoked by the Qt GUI event loop. Tests that used to call the Qt button click method directly and rely on the event to happen
    immediately will now need to update their tests to ensure that the click slot is processed by the Qt GUI event loop in the same order as before. Consider using the new testing library which automatically runs the GUI event loop after each interaction (e.g. mouse click).

Future removals

  • traitsui.image has been moved to pyface.image more than 3 years ago and has since been deprecated. Previously it was scheduled to be removed in TraitsUI 6.0. This planned removal is now deferred to TraitsUI 7.2.
