with_spinner

jdaviz.core.template_mixin.with_spinner(spinner_traitlet='spinner')

decorator on a plugin method to set a traitlet to True at the beginning and False either on failure or successful completion. This traitlet can then be used in the UI to disable elements or display a spinner during operation. Each plugin gets a ‘spinner’ traitlet by default, but some plugins may want different controls for different sections/actions within the plugin.
