OK, thank you.

Please, let me know if you'd like me to file a bug for this?
Thanks

I'm working on it. But yes, this really seems a bug in Gtk.

Hi,

Any update? Does anyone think this is a bug that should be filed against Gtk?

Thanks

Hi, I can't promise I will find a solution but I'll certainly take a look at this

You are right, and I withdraw my remarks. As noted, I didn't read it carefully enough.

But yes, g_idle_add_full() runs in the worker thread, however that's one thing that is always OK.

But that's not how the code is written:

g_task_run_in_thread(obj->task, custom_object_work) ->
  custom_object_worker() ->
     signal_emit() ->
        g_idle_add_full(..., signal_emitter, ...);

signal_emitter() is the function that *actually* emits the signal.
signal_emitter() is supposed to be running in the main context thread
by the virtue of being the g_idle_add_full() callback.

Are you saying that the g_idle_add_full() callback also runs in the
worker thread?

How is that? The update is happening from a callback executed by the
main context thread?


g_task_run_in_thread(obj->task, custom_object_worker);

custom_object_worker() emits the "updated" signal. the handler modifies the model.
