Learning, need help

[_Max_Cavalera_]

Been full of work lately.
I'm gonna try to add some more functionality to the addon, click to open the artifactUI, slash commands, unlock/lock to move the frame, maybe a right click menu to change the info shown on the main frame.
I'm gonna do these over time and post the code here as I do for review and notes from you guys, if you can obviously

I do have a question about something that I've been trying.

One thing C_ArtifactUI.GetEquippedArtifactInfo() returns is (I think) the icon from the artifact, I've tried returning it and it gives me a number and not the usual string with the icon path, I'm assuming that's the icon id?!?!
How can I get the actual icon from that? Can't find how to do it anywhere.

I'm also wondering your opinion on the way I did the tooltip, is directly making a function for OnEnter not as good or efficient as doing it on a SetScript like SDPhantom did on his example solution?

Thank you guys for all your help, when I first came here I actually wasn't expecting so much help, this is a great community.
