IPywidget optional hide close button - Suggestion

[oscar6echo]

Hi,

I see ipywidgets as a means to turn a notebook (almost) into a webappfrom the user's perspective, when the code cells are hidden.

But then the remaining 'close button' enables the user to delete the interactive widget...

So I think it would be good to be able to optionally hide this button upon creation of an ipywidget.

It is easy enough to hide all such buttons in a notebook with something like (1)

So maybe that's enough ?

It is more convoluted to do it for a particular cell with (2)

Actually it works only from the console, after selecting the target cell.

What do you think ?

Please quickly discard if there are good reasons against.

Thx

(1)

%%javascript

$('.widget-area .prompt .close').hide()

(2)

%%javascript

var jupyter= require('base/js/namespace');

var sc = jupyter.notebook.get_selected_cell();

var db = sc.widgetarea.widget_area.children()[0];

var b = db.firstChild;

$(b).css('visibility', 'hidden');

(There is probably a more direct way)

It probably makes sense to do something like this in the dashboards view. In the regular notebook view, I'm not sure we would want users to not have access to closing things, though.

I did not know that extension: I'll read carefully.
