- class shyft.dashboard.base.selector_model.SelectorModelBase(presenter: SelectorPresenter, logger=None)[source]
Bases:
object
Abstract base class for a composable selector.
The selector needs a presenter (the view controller) as input argument. In __init__ will be automatically connected to the on_change port.
The on change port is the only abstract method which is required to set. This function receives a List of str, which are the selected values in the view of the presenter. Even for a single select this will be a list, then containing a single value.
To populate the presenter with options, use the public methods of the presenter: E.g.:
>>> self.presenter.set_selector_options(['a', 'b', 'c'], callback=False, sort=True, >>> sort_reverse=False, selector_values=None)
In this manner it is also possible to set a value in the view from the backend: E.g.:
>>> self.presenter.set_selector_value(value='a', callback=False)
Note that when a value is already selected, and one sets the selection again, bokeh won’t trigger a callback

Bases:
object
Abstract base class for a text input.
The text input needs a presenter (the view controller) as input argument. In __init__ will be automatically connected to the on_change port.
The on change port is the only abstract method which is required to set. This function receives a string, which is typed in by the user in the view of the presenter.

logger – a logger
