Hi, I would like to request/discuss inclusion of xdg-desktop-portal-kde [1] into Plasma to have it released with Plasma 5.10 and so on.
What is xdg-desktop-portal-kde: It's a KDE implementation of Flatpak portals backend [2], currently with support of AppChooser, FileChooser, Notification and Print portals. How it works: An app running in sandbox communicates with outside world using org.freedesktop.portal.Foo interfaces (each of them is one portal). These interfaces are registered by xdg-desktop-portal (on DBus as org.freedesktop.portal.Desktop service). This requires support in library to make widgets etc. do calls to o.f.p.Foo interfaces instead of doing what they usually do. This is already implemented in KNotifications and for Qt part we have flatpak platform plugin. Then xdg-desktop-portal calls desktop specific implementations to present native dialogs and have proper integration. That's where xdg-desktop-portal-kde takes place. It exposes it's implementation on DBus as org.freedesktop.impl.portal.desktop.kde service. Then in case of KDE when user requests a file dialog from a sandboxed application, Qt platform plugin does a dbus call to xdg-desktop-portal instead of showing a dialog and xdg-desktop-portal forwards this to our backend implementation and we show a native dialog to the user, this time this dialog is not running in sandbox and user can open a file which is outside the sandboxed application. Same way it works with opening URLs, notifications etc. What do you think?
