Andy, Looking at Gtk code on: https://gitlab.gnome.org/GNOME/gtk/-/blob/main/gtk/gtktextview.c -> gtk_text_view_retrieve_surrounding_handler
It seems to concat 3 words backwards + selection + 3 words forward (there are more complicated cases). I was looking around on JavaFX code and it does not seem to support this feature (surrounding). I don't know if Windows and/or Mac supports it. If implemented it should work for all text input controls. Gtk seems to have been adopting relative window positioning for everything as opposed to Screen positioning and InputMethodRequests.getTextLocation is absolute. Would be nice to have the relative value. -- Thiago Em sex., 9 de jun. de 2023 às 12:49, Andy Goryachev < andy.goryac...@oracle.com> escreveu: > Thiago: > > > > The IME support is in the plans, so thank you for the info.
