Hi Johan, Robot will be a challenge.
For mouse and keyboard simulation this could work: https://www.kernel.org/doc/html/v4.12/input/uinput.html of maybe: https://docs.flatpak.org/pt-br/latest/portal-api-reference.html#gdbus-org.freedesktop.portal.RemoteDesktop For screenshot: https://docs.flatpak.org/pt-br/latest/portal-api-reference.html#gdbus-org.freedesktop.portal.Screenshot Haven't tested anything yet. I did some experiments on the jfx-sandbox (it displays the window on wayland with software rendering), but the conclusion so far is that it's better to ditch gtk and use wayland-client directly, except for system dialogs such as file open. -- Thiago.
