I need some help regarding Glade. I am new to glade programming.

I am using glade to display one simple image. What I need to do is, If I
will change the system resolution the image resolution should also
change accordingly. How can I relate system resolution with my glade code.

Can anyone please help me in this regard. I am not able to find good glade
tutorials to go through.

I am using Ubuntu and glade-3.2.0 and coding in gtk.

Please help me.

Awaiting for a quick reply.

Thanks & Regards,
