Comment:
There's a patch at
*
http://sage.math.washington.edu/home/mpatel/trac/7267/trac_7267_color_choosers.patch
The patch
* Adds both [http://www.eyecon.ro/colorpicker/ ColorPicker] and
[http://www.digitalmagicpro.com/jPicker/ jPicker].
* Adds a dedicated `color_selector()` `interact` control. The keyword
option
* `widget` selects the widget to render. The choices are
`'farbtastic'` (the default), `'jpicker'`, and `'colorpicker'`.
* `hide_box` (default: `False`) sets whether the input box is visible.
Here's a compact example:
{{{
#!python
@interact
def _(color=color_selector((1,0,1), label='', widget='jpicker',
hide_box=True)):
show(plot(x / (8/7 + sin(x)), (x, -50, 50), fill=True,
fillcolor=color))
}}}
Remarks:
* jPicker adds itself as a (grand)^n^-child of the output cell, so it's
confined to that area. This is a problem, e.g., when `auto_update=False`
and a plot disappears. The smarter !ColorPicker appends itself to
`document.body`, similarly to jQuery UI's dialogs.
* Continuously or rapidly changing ''any'' of the widgets sends so many
requests to the server that a rendered `interact`'s final color may not
match the final selected color. The server does receive the final color,
according to a print statement in `twist.Worksheet_eval`. I'm not sure
what happens to the corresponding output. Anyway, I think this is an
important but separate problem.
* In a future ticket, I'll set up one of the new choosers for user,
worksheet, and notebook settings pages. See
`sagenb.notebook.conf.Configuration.html_table()` and `server_conf` for
details.
