Behavior: how to get selected elements from 'ViewPanelWdg'/'TableLayoutWdg'?

[stefanovilla]

Hello there,
I've been working on a custom widget, extended from class 'BaseRefreshWdg'.
It has two areas: on the left there's a list of existing entities. On the right there'll be details and stuff related to selected items.
Items are selected by checking the checkbox on the left of the ViewPanel/TableLayout.

I've created the left div using 'ViewPanelWdg' (or 'TableLayoutWdg') and I've tried to add a new behavior which should get the list of selected items and pass them, within kwargs, to the right div.

And that is where I got stuck, as I know basically nothing of JS and I couldn't find any example on how to get a list of all search_keys whose checkbox is set.
Any suggestions?
Many thanks, regards,
Stefano
