pyface - Pyface 8.0.0 Latest Release

Published by corranwebster over 1 year ago

Highlights of this release

This is a major release which removes a number of things which have been deprecated for a number of years. The most significant change in this release is that the Qt toolkit backend has been moved from the pyface.ui.qt4 package to the pyface.ui.qt package. The "qt4" namespace had been an ongoing source of confusion as Qt5 and Qt6 became the most popular versions of Qt in use. Because this change has the potential to cause significant backwards compatibility issues, this release includes import hooks to continue to support imports from pyface.ui.qt4... which can be enabled by:

using "qt4" for the ETS_TOOLKIT or ETSConfig.toolkit values.
setting the ETS_QT4_IMPORT environment variable to a non-empty value
explicitly adding the import hooks to sys.meta_path

In particular the environment variables allow users of ETS-based applications such as Mayavi to continue to use those applications with newer versions of Pyface until there is time to update their code to the new import locations.

Additionally this release uses the module-level __getattr__ system introduced in Python 3.7 to delay imports from the api modules which have side-effects, particularly toolkit selection. This means that you can, for example, import pyface.api and toolkit selection will be deferred until you actually request a class or object which is toolkit-dependent. Part of this included adding formal interfaces for ActionManager and its subclasses

In addition this release:

adds support for Python 3.11 and drops support for Python 3.6
adds support for PySide 6.4+ and the new enum system
removes code supporting PyQt4, and supports more modern imports from
pyface.qt, such as pyface.qt.QtWidgets.
removes many things flagged as deprecated in Pyface 7
consistently add interface classes to api modules.
adds new Field subclasses, including an ImageField and LabelField
moves to a pyproject.toml-based packaging solution, removing setup.py

pyface - Pyface 7.4.0

Published by corranwebster over 2 years ago

Highlights of this release

This release features some significant refactoring and reorganisation of the
Pyface API aimed at making it generally more coherent. Specific changes
include:

adding intermediate interfaces and classes to collect common roles and
behaviours.
adding hooks to control widget sizing behaviour within layouts/sizers.
deprecating behavior where a class creates the underlying toolkit widget in
the __init__ method. This was done by a small minority of Widget classes,
now all widgets are able to use two-step creation (first the
instance, then the toolkit object via the create() method).
creating Qt versions of some widgets, and filling in some gaps in widget
types (particularly for Fields)
providing image classes that wrap PIL images and NumPy arrays that allow
dynamic images and icons in addition to the resource-based versions.
providing a toolkit-independent Font class and corresponding trait that
supports similar use-cases to the existing TraitsUI Font trait.
extracting the menu and toolbar Schema system from Tasks and making it more
generally useable.

All changes should be backwards compatible, and deprecated APIs have a clear
path forward.

Additionally, this release adds experimental support for Qt 6 in the pyface.qt
API. Downstream packages can use the "pyqt6" and "pyside6" values for
QT_API and CI is being run and passing with PySide6. We generally plan to
move the default development environment to Python 3.8 and PySide6 over the
next few months.

Corresponding to this, PyQt4 support is deprecated, CI is no longer being run
for PyQt4 (which has been at end-of-life since 2015) and remaining support for
PyQt4 will be removed in the next major release.

pyface - Pyface 7.0.0

Published by corranwebster over 4 years ago

Pyface 7.0.0 is a major release which focuses on modernization of the
codebase. This release includes updating the WxPython backend to support
WxPython 4, an effort led by Rob McMullen's first cut at support, with
help from a number of other people. It also updates the code to use new
features of Traits 6, and just like Traits 6, this release drops support
for Python 2.

The release includes many bugfixes and a number of smaller incremental
enhancements. Other than the changed dependencies, Pyface 6 code should
largely work unmodified under Pyface 7.

pyface - Pyface 6.1.0

Published by corranwebster over 5 years ago

This release introduces a number of new features and bugfixes. The most prominent of these is a set of Application classes designed to smooth the transition between Tasks applications which use only Pyface, and those that take advantage of the Envisage plug-in framework. Developers can now write a Pyface TasksApplication and then easily transition to an Envisage TasksApplication as the needs of their codebase grows. This feature has been a few years in development, and thanks is due to Jonathan Rocher for helping push this through to completion.

This release also includes a complete re-write of the Pyface timer code to make it easier to use and to provide a consistent and more Pythonic API shared by the different back-ends. A backwards compatible API is still available, but users of the Pyface timer code are encouraged to update to the new API.

ToolBars can now embed simple widgets, such as text fields, integer spinners, and comboboxes, as well as simple TraitsUI views. This is provided via a new "widget" style for Actions as well as the utility subclasses FieldAction and TraitsUIWidgetAction.

Although not visible to most users of Pyface, this release removes the use of 2to3 and now uses a unified codebase supported by the six library. Thanks to Rahul Poruri for performing this transformation. This should help significantly with ongoing development work in the coming years.

We also include experimental support for PySide2 (also called "Qt for Python"). We are running CI tests using the 5.11 release of PySide2 with success on OS X and Linux for Python 3, but are experiencing failures with the 5.12 release.

Finally, this release includes a number of bugfixes and minor enhancements which should improve the reliability and utility of the codebase.
