| /*
 | |
|     Look for confirm_dialog in settings_user_groups
 | |
|     to see an example of how to use this widget.  It's
 | |
|     pretty simple to use!
 | |
| 
 | |
|     Some things to note:
 | |
| 
 | |
|         1) We create DOM on the fly, and we remove
 | |
|            the DOM once it's closed.
 | |
| 
 | |
|         2) We attach the DOM for the modal to conf.parent,
 | |
|            and this temporary DOM location will influence
 | |
|            how styles work.
 | |
| 
 | |
|         3) The cancel button is driven by bootstrap.js.
 | |
| 
 | |
|         4) For settings, we have a click handler in settings.js
 | |
|            that will close the dialog via overlays.close_active_modal.
 | |
| 
 | |
|         5) We assume that since this is a modal, you will
 | |
|            only ever have one confirm dialog active at any
 | |
|            time.
