Slider update using arrow keys stopped working

i’ve been using the keyboard arrow keys to update a slider but it seems to have stopped working after upgrading to 0.12.9. is this a known issue?

brian

Hi,

If it worked before then it was an unknown and unintended incidental and accidental behavior. However the underlying JS library for sliders changed in 0.12.9 so that probably explains any differences in undocumented behaviors. I'd suggest a GH issue to make a new feature request.

Thanks,

Bryan

that’s unfortunate. the ability to use the mouse for coarse updates and arrow keys for fine updates was very useful and it’s become a requirement for my application. is there a way i can replicate that behavior in my customJS callback? i can’t find in the documentation where i can read keyboard events in the callback.

Hi,

There are no keyboard events. I am a strong -1 on adding general keyboard events, because I am not interested in making it trivial for people to use Bokeh to build silent key loggers.

I am definitely not opposed to adding keyboard control back to sliders, as a specific feature, with a limited, constrained implementation that does not leak user data. I am only saying that it was an "accidental" feature previously (I didn't know it existed, for example) so that adding it now will mean new feature development, in a way that maintains the documented capability under test. Which I am happy to discuss (but GitHub is the appropriate place).

Otherwise the only suggestion I can make for an immediate option is to create your own custom extension:

Thanks,

Bryan
