Hi, I'm writing a GTK3 dictionary app in Vala. It has a GtkEntry with a GtkEntryCompletion, that it uses to provide word suggestions based on what you've typed. Think Google's search box. The way I've implemented this is by connection to the "changed" signal, and dispatching a new async libsoup request to grab the word suggestions with a callback that parses them and inserts them into the GtkListStore that is the model of the GtkEntryCompletion.
I understand it, the GtkEntryCompletion was designed on the assumption that it would have access to the entire pool of possible suggestions. Obviously, this is not the case with my application as it only knows about the few suggestions it returns from the net. Because of this I believe the API is slightly awkward (or at least, the way I'm using it, hence my writing this). My implementation works fine when typing "forward" (i.e going from "fo" to "foo" -- adding letters, not deleting them), but seems to flash and stutter when pressing backspace. Whereas in forward typing the pop-up box suggestions instantly visually change to their updated forms based on the new letters being typed, when hitting backspace the entire pop-up box goes blank, then repopulates entirely, making the experience look jittery and somewhat annoying. I actually cache old results in RAM, so it's not even going over the wire when typing backwards -- just reading from a datatype in RAM, so I know there isn't some issue with it being slow because of the internet connection. Is this behavior normal? Why should it only happen when hitting backspace, but not when typing? What, if anything, can I do to fix it? *tl;dr* GtkEntryCompletion popup visually clears and repopulates when hitting backspace.
