HI - OK so I now have a custom button working on the 4.x version of Tiny MCE with one exception: I can't get any icon to show up on the button itself.
I think I understand this to be a matter of referencing an existing icon, but I don't know how to determine what the options are.
Also, would I apply the icon value directly in the plgin.min.js I've created for the button in the plugins directory?
Anyone familiar with this?
Here's the page:
The last button on the bar does exactly what it's supposed to, but I can't get an icon to show...
