Make editable sliders name parameter editable (from python)

[TheoMathurin]

Editable sliders are a very nice addition to panel components and can advantageously replace conventional sliders in most cases in my opinion. However there is a difference currently with respect to the name parameter, which is constant in editable sliders while it is not in conventional sliders.

As in my app I use sliders which have their name changed programmatically, I would like to know if editable sliders could be modified so that the name parameter is no longer constant? In general I think it's best to make editable sliders behave identically to their non-editable counterparts as far as practicable.

Hi @TheoMathurin. Could you provide a small, reproducible code example? That would make it easier to reproduce, explore, fix and release. Thanks.

And for me to probably show you a temporary workaround :-)

Hi @MarcSkovMadsen

Sure

import panel.widgets as pnw

slider = pnw.EditableFloatSlider(name='name1')
slider.param.set_param(name='name2')

Thanks in advance

I tried to find a workaround but it errors

import param
import panel.widgets as pnw
import panel as pn

pn.extension()

slider = pnw.EditableFloatSlider(name='name1')

with param.edit_constant(slider):
    slider.name='name3'

slider

TypeError: Constant parameter 'name' cannot be modified

[TheoMathurin]

That is the same error you get when trying to modify it directly.

The work around is :
slider._label.param.set_param(**{'margin': (0,10,0,0), 'value': "name3"})

[TheoMathurin]

It works, thanks @xavArtley!

try:
    slider.name =  "name3"
except TypeError:
    pass

also works. This is because the name of the widget is actually being correctly set in the first place (under the hood the value of a StaticText widget is set). However, the code currently sets the name of the Column param that wraps the StaticText and the slider. The name of any param can be set but not edited, which is what raises the error.
