Body
I have a chat application on Node.js and Socket.io, user can connect and disconnect with a button... I am having a list of online users which is perfectly managed with the help of my defined events that user trigger. But the problem is I am unable to detect if the user has lost his connection or closed the browser window without disconnecting himself manually(by the disconnect button)... This socket.io event is fired only when user disconnects himself not when he lost his connection. <pre><code>socket.on('disconnect',function(){ console.log('user disconnected'); }); </code></pre> I want some really good mechanism to keep an eye on users in order to update my Online users list.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
