[docs]def urlOpen(url, output, target='_blank'):
"""
Opean a web page in another tab of the browser
Parameters
----------
url : str
URL of the page to open
output : instance of ipywidgets.Output() class
Output widget where the javascript code to open the new page is executed
target : str, optional
Target of the open operation (default is '_blank' which means that the page will be opened in a new browser's tab)
Example
-------
Open Google page in another tab of the browser::
from vois import urlOpen
from ipywidgets import widgets, Layout
from IPython.display import display
output = widgets.Output(layout=Layout(width='0px', height='0px'))
display(output)
urlOpen.urlOpen('https://www.google.com', output, target='_blank')
Note
----
If the dashboard is created using the :class:`app.app` class, it is preferable to use the function :func:`app.app.urlOpen` that doesn't need the output parameter and uses the Output widget created inside the app instance itself (and invisible to the users)
