I would like to add a double click handler to the "Insert New Component" dialog in CQ.
The code that generates this dialog is in EditBase.js : /libs/cq/ui/widgets/source/widgets/wcm/EditBase.js. "getEditConfig()" at line 582 seems to return the dialog that I want, and it was a render listener declared. I can add a console log here and see it when I display an "Insert New Component" dialog. What would be the steps to adding a double-click listener? Is there one currently that I can modify?
Create an overlay for it?
I doubt you are at right place. What is your exact use case? On doubleclick on components inside New component dialog you want to fire something?
