widgets and setting to enable play when play button is pressed (ie is playable??)

I have recently been making some modifications to my preferred skin (titan bingie) and have managed to fix some things, move some things and generally do what i have been trying to do (eg only show the new episode overlay or the tag overlay but not both, or to use tmdbhelper instead of openmeta to open the next episode, to not show a bunch of overlays which darken the fanart etc)

However I am unable to figure out how to enable the widgets so that when you click play on the remote they open the episode or movie, currently I click play and nothing happens. When i click ok on the items it will open tmdbhelper (from my library widgets or whatever other widget) or the info screen and openinfo, that all works fine. Or it does now anyway.

But the widget items are just not playable with the "HandleKey: homepage (0xea) pressed, action is PlayPause".  Ive tried searching for stuff but its hard to search for stuff like "click play","playable" etc because so much non specific stuff comes back.

Ive tried looking at some other skins to see if I can see anything obvious, the widgets are totally presenting playable items, eg an XSP episodes playlist, or an addon trakt list. So im figuring its the actual widget setup.

Ive seen some stuff in unfussy:

<!-- Widget -->
<include name="widget_mainmenu">
<param name="id"></param>
<param name="visible">true</param>
<param name="header"></param>
<param name="type">movies</param>
<param name="height">250</param>
<param name="itemwidth">260</param>
<param name="path"></param>
<param name="static_content">false</param>
<param name="target">video</param>
<param name="sortby"></param>
<param name="sortorder">ascending</param>
<param name="onclick"></param>
<param name="useonclick">false</param>
<param name="limit"></param>
<param name="showplaystatus">false</param>

So stuff like type,target,showplaystatus and potentially onclick seem like they might have some relevance but ive added these to the widget includes for the types of widgets i have setup and it didnt make any difference, click play and nothing happens.
I had added static content false and the widgets reloaded when they normally wouldn't, so i'm pretty certain my additions to the widgets includes were having some effect.


So can anyone tell me how you setup a widget so when you click play on the remote it plays the widget item, in addition to being able to click on the item and play it or play it from the context menu (which works fine)?
