Hello all,
I am playing around with interfacing some custom hardware that I've built for my PhD to the GIMP. I spent some time yesterday learning how to add popup menus to the UI, so that I could right-click a slider (such as the Cyan / Magenta / Yellow ones in the Color Balance dialog), and bind the slider to data from my input device on-the-fly. I got the popup menu to pop and show the menu entries that I have identified, but after popping the menus a few times, GIMP always crashes with this message:
(gimp-2.4:23363): Gtk-CRITICAL **: gtk_window_set_accept_focus: assertion `GTK_IS_WINDOW (window)' failed
Bus error
Does anyone know how my popup menus caused that, and how I can fix it?
The more general question that I have is the following: If I want to route control messages to and from a Python interpreter that I instantiate in the GIMP, what would be the most elegant way to run this interpreter and to route messages? (this is for dynamically controlling the UI - for instance, to make my hardware control the aforementioned sliders, so I don't think I can use the same Python architecture that does plugins). Is there a general message-passing system that I could hook into? Where should I look, to get started?
thanks in advance!
