collective.progressbar

This product provides a basic html and javascript progress bar for Plone that are useful for long running server side processes like imports or exports.

To use it, you simply have to fire two events. The first event initialises the progress bar view:

from collective.progressbar.events import InitialiseProgressBar
from collective.progressbar.events import ProgressBar

title = 'Importing file'
bar = ProgressBar(self.context, self.request, title)
notify(InitialiseProgressBar(bar))

The ProgressBar class above can take an optional view parameter if you want to customise the view that renders the progress bar further. You only have to include the progressbar macro in your custom view.

To update progress, you simply have to fire the appropriate event:

from collective.progressbar.events import UpdateProgressEvent
from collective.progressbar.events import ProgressState

for index in range(101):
    progress = ProgressState(self.request, index)
    notify(UpdateProgressEvent(progress))

To see how the progress bar works, install the package and browse to the demo view eg.: http://localhost:8080/plone/@@collective.progressbar-demo
