c++ - Are GTK Callbacks called from the main thread when using gtk_main_iteration? -


normally when using gtk3 callbacks gtk_main() function, expected callbacks maybe running in seperate thread programs main thread, , therefore thread safety measures need taken ensure callbacks thread safe.

however, if main thread deals gtk main events manually using gtk_main_iteration?

// processing here while (gtk_events_pending()) {     gtk_main_iteration(); } // more processing here

in situation, callbacks still run in separate thread? or launched main thread?

my program has lot going on , if turns out callbacks called main thread in setup, save me quite bit of thread safety work.

note: i'm working gtk3, believe applies both gtk2 , gtk3
