Drawing
The focus is drawn with a detail of checkbutton. The check is drawin with the gtk_paint_check function, detail is checkbutton. The shadow for the check depends on whether the checkbox is checked, etc.

ETCHED_IN |
inconsistent state, if it is neither on nor off |
When the checkbox prelights, it additionally draws a flat box with detail checkbutton and shadow ETCHED_IN. (XXX: It looks to me like you can only draw solid colors in here, because it only draws the reexposed area, so if you get a partial expose then things might break.)
Button Look
Note that an application may disable the check and get a widget that looks like a toggle button. This is rather annoying for themes if they want to change the text colour for buttons, but not for check buttons. (I have yet to see an application that uses this though.)
