The display target called (name) is now ready and available to show slides. This event is useful with display widgets where you want to add a display to an existing slide which shows some content, but you need to make sure the display exists before showing a slide. So if you have a display called “overlay”, then you can add it to a slide however you want, and when it’s added, the event “display_overlay_ready” will be posted, and then you can use that event in your slide_player to trigger the first slide you want to show. Note that this event is posted by MPF-MC and will not exist on the MPF side. So you can use this event for slide_player, widget_player, etc., but not to start shows or other things controlled by MPF.
This event does not have any keyword arguments
