chaco.examples.demo.chaco_trait_editor module¶
An example of how to use Chaco to render a visual TraitsUI editor. This particular editor allows the user to set two endpoints of an interval.

traits.trait_type.TraitTypeTrait that represents an interval.
-
create_editor()¶ Returns the default traits UI editor to use for a trait.
-
info_text= 'an interval (x,y) where x < y'¶
-
validate(object, name, value)¶
-
-
chaco.examples.demo.chaco_trait_editor.IntervalEditor¶ alias of
chaco.examples.demo.chaco_trait_editor.IntervalEditorFactory
-
class
chaco.examples.demo.chaco_trait_editor.IntervalEditorFactory(*args, **traits)¶ Bases:
traitsui.editor_factory.EditorFactory-
simple_editor(ui, object, name, description, parent)¶ Generates an editor using the “simple” style.
-
-
class

-
update_editor()¶ Updates the editor when the object trait changes externally to the editor.
-
update_interval(event)¶
-
-
class
chaco.examples.demo.chaco_trait_editor.IntervalTest¶ Bases:
traits.has_traits.HasTraits
-
class
chaco.examples.demo.chaco_trait_editor.RangeKnobsOverlay(component=None, *args, **kw)¶ Bases:
