Bokeh open file diaB

Hi all,

i cant find a way to open a simple select file dialog. I would like to have a button called “load”, if pressed shows a open file dialog and returns after the file selection the full file path to a callback function.

my files are stored on the same machine as the bokeh server runs.

Thanks for your help

Ivo

Hi Ivo,

As of Bokeh 0.11.1 there is no built-in file chooser dialog, so this would represent new development. I did not see an existing feature request issue on our tracker, so I'd encourage you to go there and add a feature request for this feature:

  https://github.com/bokeh/bokeh/issues

In the mean time, it is possible to extend Bokeh with your own custom models, e.g. to wrap some JavaScript library you like, and integrate it with Bokeh. Unfortunately this is a little bit involved, and writing more docs about this specific capability is still a work in progress. However I can point you to an example:

  https://github.com/bokeh/bokeh/blob/master/examples/models/custom.py

And if you want to try and make a custom model for some JS file chooser dialog, we would definitely try to answer any questions.

Barring that, the best immediate suggestion I can offer is to leverage the existing DataTable widget somehow, by populating it with paths and responding to selection events on it.

Thanks,

Bryan

Hi Bryan

Thank you very much for your detailed answer. I appreciate it a lot.

I was thinking about writing a widget but could not find any information. Thank you very much for the example.

For now I will go for the DataTable - Thank you for that particular hint.

Greetings

Ivo
