Re: How to make a GtkButton respond to a key press
When using Glade to design a UI, I've noticed that the Button dialog has an Activatable/Actionable section which includes an on/off Use Action Appearance selection. This suggests that you might look into GtkActionable and kin...

For example, if I made a simple calculator like the one that comes with Gnome, how can I make it so when I press '1' on my keyboard, the 1 button presses. I know how to make shortcuts with a control key by just putting in an in the label. But not just a bare key press. Also is it possible to programmatically depress and then release a GtkButton, simulating a click? I'd like to do this to generate some user feedback when the keyboard is used, while allowing one to still click with a mouse (or finger or whatever) on the GtkButton.
