User Documentation

Documentation on using URL Dispatcher as an application developer is now available on the developer website:

URLs with multiple handlers

(bug 1378350)

Whenever the URL dispatcher is called on to open an address that multiple apps have registered for, it should open a “Use App” dialog, with a centered grid of labelled buttons with the icon for each applicable app, followed by a “Cancel” button.

Unsupported URLs

(bug 1370008)

Whenever the URL dispatcher is called on to open an address of a protocol that it does not understand (url-dispatcher-bad-url), it should open an alert with the title “Unrecognized Address”, text of the form ‘Ubuntu can’t open addresses of type “{protocol:}”.’, and an “OK” button. To prevent denial of UI service, however, the alert should not open if it has already opened more than three times in the past minute.
