Description:
desktop integration portal for Flatpak
xdg-desktop-portal provides a portal frontend service for Flatpak, and possibly other desktop containment/sandboxing frameworks. This service is made available to the sandboxed application, and provides mediated D-Bus interfaces for file access, URI opening, printing and similar desktop integration features. . The implementation of these interfaces is expected to require user confirmation before responding to the sandboxed application's requests. For example, when the sandboxed application ask to open a file, the portal implementation will open an "Open" dialog outside the sandbox, and will only make the selected file available to the sandboxed app if that dialog is confirmed. . xdg-desktop-portal is designed to be desktop-agnostic, and uses a desktop-environment-specific GUI backend such as xdg-desktop-portal-gtk to provide its functionality.
