TraitsUI: Traits-capable windowing framework
The TraitsUI project contains a toolkit-independent GUI abstraction layer, which is used to support the "visualization" features of the Traits package. Thus, you can write model in terms of the Traits API and specify a GUI in terms of the primitives supplied by TraitsUI (views, items, editors, etc.), and let TraitsUI and your selected toolkit and back-end take care of the details of displaying them.
The following GUI backends are supported:
Warning: In TraitsUI version 5.0 the default GUI backend was changed from
Given a Traits model like the following:
from traits.api import HasTraits, Str, Range, Enum class Person(HasTraits): name = Str('Jane Doe') age = Range(low=0) gender = Enum('female', 'male') person = Person(age=30)
we can use TraitsUI to specify a and display a GUI view:
from traitsui.api import Item, RangeEditor, View person_view = View( Item('name'), Item('gender'), Item('age', editor=RangeEditor(mode='spinner')), buttons=['OK', 'Cancel'], resizable=True, ) person.configure_traits(view=person_view)
which creates a GUI which looks like this:
If you want to run traitsui, you must also install:
along with one of the GUI backends.
