Still fairly new to WAB, and dojo on the whole, so perhaps this has a simple answer.
Take, for example, the out-of-the-box version 1.2 Search widget. Inside its .js file is the following few lines:
this.own(
on(this.searchDijit, 'select-result', lang.hitch(this, '_onSelectResult'))
);
I'm wondering if there's away to hitch on to this exact same event from another custom non-panel widget. The desired behavior is that whenever the out-of-the-box Search widget's searchDigit fires its 'select-result' event, this other custom widget can perform an action as well, using the same argument object that is passed to the local Search's event handler.
