Right. My statement was overly strong: gtk.main_iteration() alllows you to single-step the gtk main loop at (programmatically defined) intervals, i.e. you needn't be in gtk_main() to process idle callbacks. I don't know enough about your program to know whether that's useful to you or not. > > [..] >>> But >>> I don't understand the other situation: why I cannot catch the >>> NSApplicationOpenFile signal if I call gtkosx_application_ready() when >>> gtk_main is already running. >> >> [snip explanation of OpenFile handling] > > But why does it not work if I connect the signal and start gtk_main() > and *after that* call gtkosx_application_ready()...? Yes, I just noticed I was answering a slightly different question to the one you asked. The gtk-osx integration code defines a GtkApplicationDelegate, which processes OpenFile file events for the NSApp and emits the NSApplicationOpenFile signal. So my guess is that this delegate isn't registered until gtkosx_application_ready() is called. However, checking this by the code I get muddled, as this object is only created in static void gtkosx_application_init, which is never called in the file in which it is defined (gtk-mac-integration-2.0.1/src/gtkosxapplication_quartz.c), as far as I can tell. best, Richard. _______________________________________________ Gtk-osx-users-list mailing list Gtk-osx-users-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-osx-users-list
