org.freedesktop.portal.Request:
|
|
@short_description: Shared request interface
|
|
|
|
The Request interface is shared by all portal interfaces. When a
|
|
portal method is called, the reply includes a handle (i.e. object path)
|
|
for a Request object, which will stay alive for the duration of the
|
|
user interaction related to the method call.
|
|
|
|
The portal indicates that a portal request interaction is over by
|
|
emitting the #org.freedesktop.portal.Request::Response signal on the
|
|
Request object.
|
|
|
|
The application can abort the interaction calling
|
|
org.freedesktop.portal.Request.Close() on the Request object.
|
|
|
|
Since version 0.9 of xdg-desktop-portal, the handle will be of the form
|
|
|
|
::
|
|
|
|
/org/freedesktop/portal/desktop/request/SENDER/TOKEN
|
|
|
|
|
|
where ``SENDER`` is the callers unique name, with the initial ``':'`` removed and
|
|
all ``'.'`` replaced by ``'_'``, and ``TOKEN`` is a unique token that the caller provided
|
|
with the handle_token key in the options vardict.
|
|
|
|
This change was made to let applications subscribe to the Response signal before
|
|
making the initial portal call, thereby avoiding a race condition. It is recommended
|
|
that the caller should verify that the returned handle is what it expected, and update
|
|
its signal subscription if it isn't. This ensures that applications will work with both
|
|
old and new versions of xdg-desktop-portal.
|
|
|
|
The token that the caller provides should be unique and not guessable. To avoid clashes
|
|
with calls made from unrelated libraries, it is a good idea to use a per-library prefix
|
|
combined with a random number.
