Adding Panels dynamically to Tabs widget

I am trying to add Panels dynamically to a Tabs object:

So I first initialize a Tabs object with no panels

Add empty list of tags

DOC = bokeh.io.curdoc()
TABS = bokeh.models.widgets.Tabs(name=‘memory_tabs’, tabs=)
DOC.add_root(TABS)

I have tried to add panels to the TABS object, but they do not render, what is the best way to do this on-the-fly?

Thanks!

There seem to stil be some issues specifically around updating layouts to resolve with the server. So you may have run into a but. But it is impossible to speculate without being able to see and run real code. Can you provide a complete, minimal, runnable test case to reproduce the issue you are seeing?

Thanks,

Bryan

The following app is in essence what I am trying to do. Every 5 seconds it creates a new Panel and updates the tabs object.

Running your code I see an error in the browser JS console:

  [bokeh] – "Error handling message: TypeError: undefined is not an object (evaluating 'n.id'), [object MessageEvent]"

But your code looks reasonable at a glance, so this definitely seems like a bug. I'm not sure whether or not there's an existing issue to cover this (it's worth a quick search probably). But I'd suggest making a GH bug report or adding a comment to an existing one, with this test case.

Thanks,

I am able to dynamically add tabs. Script is below. I am not sure how to delete tabs though.

import numpy as np

from bokeh.io import curdoc

from bokeh.layouts import row, widgetbox,column

from bokeh.models import ColumnDataSource

from bokeh.models.widgets import Slider, TextInput, Button

from bokeh.plotting import figure

from bokeh.models.widgets import Tabs

from bokeh.models.widgets import Panel

TABS_LIST =

TABS = Tabs(tabs=TABS_LIST)

def create_slider_tab():

N = 200

x = np.linspace(0, 4*np.pi, N)

y = np.sin(x)

source = ColumnDataSource(data=dict(x=x, y=y))

Set up plot

plot = figure(plot_height=400, plot_width=400, title=“my sine wave”,

tools=“crosshair,pan,reset,save,wheel_zoom”,

x_range=[0, 4*np.pi], y_range=[-2.5, 2.5])

plot.line(‘x’, ‘y’, source=source, line_width=3, line_alpha=0.6)

Set up widgets

text = TextInput(title=“title”, value=‘my sine wave’)

offset = Slider(title=“offset”, value=0.0, start=-5.0, end=5.0, step=0.1)

amplitude = Slider(title=“amplitude”, value=1.0, start=-5.0, end=5.0)

phase = Slider(title=“phase”, value=0.0, start=0.0, end=2*np.pi)

freq = Slider(title=“frequency”, value=1.0, start=0.1, end=5.1)

Set up callbacks

def update_title(attrname, old, new):

plot.title.text = text.value

text.on_change(‘value’, update_title)

def update_data(attrname, old, new):

Get the current slider values

a = amplitude.value

b = offset.value

w = phase.value

k = freq.value

Generate the new curve

x = np.linspace(0, 4*np.pi, N)

y = anp.sin(kx + w) + b

source.data = dict(x=x, y=y)

for w in [offset, amplitude, phase, freq]:

w.on_change(‘value’, update_data)

Set up layouts and add to document

inputs = widgetbox(text, offset, amplitude, phase, freq)

tab_layout = column(row(inputs, plot, width=800))

tab = Panel(child=tab_layout, title=“Sliders”)

TABS_LIST.append(tab)

TABS.update(tabs=TABS_LIST)

def select_click():

create_slider_tab()

button = Button(label=“Select”)

button.on_click(select_click)

main_tab_layout = column(row(button))

tab = Panel(child=main_tab_layout, title=“Main”)

TABS_LIST.append(tab)

TABS.update(tabs=TABS_LIST)

curdoc().add_root(TABS)

curdoc().title = “Sliders”

How you find out which methods are available for “tabs” object? For example, I couldn’t Tabs.update() anywhere in the document or in the source code.
