Hi,
I just updated to Ubuntu 13.10 and I have no support for
gdk_threads_enter();
gdk_threads_leave();
So, my app is crashing with signal errors. I use a GtkTextView to enter midi data from a midi keyboard. The midi keyboard sends and event to a jack callback process, which then sends a message to a GtkTextView. And there is a thread issue because the midi jack callback is entering into the gtk_main(). So, in the past gdk_threads_enter(); gdk_threads_leave(); worked wonders for me. But, now no support.
Why would a JACK callback call gtk_main()? Something sounds wrong here.
Is there a work around for this depreciation?
The correct way to do this is to use gdk_threads_idle_add to schedule a method to be run on the UI thread. You can pass any data you want in here, e.g. the message to send ot the GtkTextView.
