UPDATE: After further testing on a recent project, I’ve found that this method still wasn’t a full solution, as the events list view still fetched the default content/sidebar layout.
There’s a more suitable filter to hook into to force the layout

The challenge: display the main events page with the full width template, and the single events with the default Genesis layout.

It took me a while to figure this out, so I want to write it down while it’s fresh in my mind and hopefully it can save someone else some time and grief.

I first played around with the Tribe custom templates, explained in detail here:
http://tri.be/support/documentation/events-calendar-themers-guide/#templates

This does not work with Genesis.

Then I found this lengthy tutorial from Tribe themselves and thought I was saved.
http://tri.be/tutorial-integrating-the-events-calendar-w-genesis/

This solution does not work anymore. Well, it has part of the solution which is the genesis_pre_get_option_site_layout

The strange thing is that the filter wasn’t getting fired on the Events pages. I did a search for that filter in the Genesis code, but couldn’t find it, even stranger. Turns out the last part of the filter name is actually a variable, so that’s why I couldn’t find it!
What it does is allow you to filter any Genesis option dynamically, you just need to know the option key – in this case ‘site_layout’.
Ok, so with this knowledge, why isn’t the filter firing for this particular option? Well, I figured that the plugin didn’t know about it, and that made me remember a code snippet from wpsmith that enables Genesis layouts on custom post types. By the way, bookmark that site, it’s awesome. Thanks Travis!
This is what I ended up with

Ok, now the next step was to set the option for the ‘tribe_events’ custom post type. Just go to a single event, and select the layout you want, then save. This will set the ‘site_layout’ option for this post type enabling the genesis_pre_get_option_site_layout filter to fire.
Now just use this snippet to force a layout for the calendar view:

EDIT: if you’re forcing the layout to full width content, you may need to disable the sidebars as an extra step. I don’t know why they are being displayed though.

That’s it. An essential part of being a good WordPress developer is the ability to remember solutions you used in the past and adapt them to solve new problems
