A Popover is closed automatically if you click outside of it. Esc and outside click is basically the same thing. In any other circumstances it is the developer who closes it, for instance when an action is selected. So there shouldn't be any difference between handling Esc or outside click. Any other closing case can be captured by the actions assigned to close the Popover.
I see the Browser's bookmarking popover has a Cancel action on the bottom. This is pretty confusing as Popovers are not Dialogs, which would need an explicit action on their layout to be able to close - Esc or outside click does the job. But really, what si the use case you need to know the Popover was dismissed? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1546677 Title: Popovers doesn’t allow overriding onEscapePressed Status in ubuntu-ui-toolkit package in Ubuntu: New Bug description: With the fix for bug #1523828, popovers are automatically closed when ESC is pressed. This is a good default behaviour, however the implementation is unfortunate: because the escapePressed handler is defined on the foreground (a child item of the root popover), app developers don’t get a chance to override it. Here’s a concrete use case: in the browser, when bookmarking a page with Ctrl+D, a popover with bookmark options is shown. We want the Enter key to validate the options and save the bookmark, and the ESC key to remove the bookmark.
