Portal#

class Portal(**properties: Any)#

Superclasses: Object

Implemented Interfaces: Initable

Context for portal calls.

The XdpPortal object provides the main context object for the portal operations of libportal.

Typically, an application will create a single XdpPortal object with new and use it throughout its lifetime.

Constructors#

class Portal

classmethod initable_new() → Portal | None#: Creates a new Portal object.

Added in version 0.7.

classmethod new() → Portal#: Creates a new Portal object. If D-Bus is unavailable this API will abort. We recommend using initable_new() to safely handle this failure.

Methods#

class Portal

access_camera(parent: Parent | None, flags: CameraFlags, cancellable: Cancellable | None = None, callback: Callable[[Object | None, AsyncResult, Any], None] | None = None, data: Any = None) → None#

Request access to a camera.

When the request is done, callback will be called. You can then call access_camera_finish to get the results.

Parameters:

parent – parent window information
flags – options for this call
cancellable – optional Cancellable
callback – a callback to call when the request is done
data – data to pass to callback

access_camera_finish(result: AsyncResult) → bool#

Finishes a camera acess request.

Returns the result as a boolean.

If the access was granted, you can then call open_pipewire_remote_for_camera to obtain a pipewire remote.

Parameters:: result – a AsyncResult

add_notification(id: str, notification: Variant, flags: NotificationFlags, cancellable: Cancellable | None = None, callback: Callable[[Object | None, AsyncResult, Any], None] | None = None, data: Any = None) → None#

Sends a desktop notification.

The following keys may be present in notification:

title s: a user-visible string to display as title
body s: a user-visible string to display as body
icon v: a serialized icon (in the format produced by serialize)
priority s: “low”, “normal”, “high” or “urgent”
default-action s: name of an action that
will be activated when the user clicks on the notification
default-action-target v: target parameter to send along when
activating the default action.
buttons aa{sv}: array of serialized buttons

Each serialized button is a dictionary with the following supported keys:

label s: user-visible lable for the button. Mandatory
action s: name of an action that will be activated when
the user clicks on the button. Mandatory
target v: target parameter to send along when activating
the button

Actions with a prefix of “app.” are assumed to be exported by the application and will be activated via the org.freedesktop.Application interface, others are activated by emitting the notification_action_invoked signal.

It is the callers responsibility to ensure that the ID is unique among all notifications.

To withdraw a notification, use remove_notification.

Parameters:

id – unique ID for the notification
notification – a Variant dictionary with the content of the notification
flags – options for this call

Parameters:: result – a AsyncResult

Asks the user to open one or more files.

The format for the filters argument is a(sa(us)). Each item in the array specifies a single filter to offer to the user. The first string is a user-visible name for the filter. The a(us) specifies a list of filter strings, which can be either a glob pattern (indicated by 0) or a mimetype (indicated by 1).

Example: [('Images', [(0, '*.ico'), (1, 'image/png')]), ('Text', [(0, '*.txt')])]

The format for the choices argument is a(ssa(ss)s). For each element, the first string is an ID that will be returned with the response, te second string is a user-visible label. The a(ss) is the list of choices, each being a is an ID and a user-visible label. The final string is the initial selection, or "", to let the portal decide which choice will be initially selected. None of the strings, except for the initial selection, should be empty.

As a special case, passing an empty array for the list of choices indicates a boolean choice that is typically displayed as a check button, using "true" and "false" as the choices.

Example: [('encoding', 'Encoding', [('utf8', 'Unicode (UTF-8)'), ('latin15', 'Western')], 'latin15'), ('reencode', 'Reencode', [], 'false')]
